In the essay possible thematic connections between Copernicus and Lyotard are elaborated. In his late opus Lyotard elaborates the problematic of making the invisible visible, presenting the unpresentable, the emergence of something new. This theme not only throws new light on the very emergence of the Copernican revolution, if there ever was one, but also presents something which is at the very heart of the dispositive of modern science as such: a link between contingency, necessity and impossibility, elaborated by (...) Lyotard through his new yet unfinished conceptions of time, cause and subject. Finally, some paradoxes of Lyotard’s project carried out in the name of the second Copernican turn are shown. (shrink)

Resumen En la década del noventa del último siglo apareció en Alemania el así denominado “giro icónico” (ikonische Wende). Keith Moxey (2009) interpretará este viraje como un nuevo paradigma que, harto del giro lingüístico y la tesis del acceso mediado a la realidad, propone a la imagen como una instancia de acceso inmediato al mundo, eliminando la distinción entre sujeto y objeto. Sin embargo, Boehm sostiene que el giro icónico debe entenderse a partir del giro de todos los giros, el (...) giro trascendental kantiano. La hipótesis que defenderé aquí es que el giro icónico debe entenderse como un pensamiento postkantiano. Abstract The 1990s saw the emergence in Germany of the so-called “iconic turn” (ikonische Wende). Keith Moxey (2009) interprets this turn as a new paradigm that, fed up with the linguistic turn and the thesis of mediated access to reality, proposes the image as an instance of immediate access to the world, eliminating the distinction between subject and object. However, Boehm argues that the iconic turn must be understood on the basis of the turn of all turns, the Kantian transcendental turn. The hypothesis I will defend here is that the iconic turn is to be understood as a post-Kantian thought. (shrink)

Alberto Coffa used the phrase "the Copernican turn in semantics" to denote a revolutionary transformation of philosophical views about the connection between the meanings of words and the acceptability of sentences and arguments containing those words. According to the new conception resulting from the Copernican turn, here called "the Copernican view", rules of use are constitutive of the meanings of words. This view has been linked with two doctrines: (A) the instances of meaning-constitutive rules are (...) analytically and a priori true or valid; (B) to grasp a meaning is to accept its rules. The pros and cons of different versions of the Copernican view, ascribable to Wittgenstein, Carnap, Gentzen, Dummett, Prawitz, Boghossian and other authors, will be weighed. A new version will be proposed, which implies neither (A) nor (B). (shrink)

The article analyzes the metaphor “Copernican revolution,” used by Kant to highlight the core idea of his philosophy. The author argues that Kant uses the analogies with mathematics and natural science for establishing criteria of scientific character of knowledge. These criteria include the hypothetic-deductive or a priorimethod of thinking, which determines the apodictic, i.e. necessary and objective, character of the basic laws of nature, as well as the verification of laws a priorithrough experiments.The author focuses on Kant’s idea of (...) the possibility of scientific metaphysics based on these criteria. She claims that the structure of scientific metaphysics and the epistemological status of its statements depend on what kind of objects it deals with: with phenomena given to us by sensuality, with only conceivable “things in themselves” or with supersensitive “objects of an idea.” In the last part, the author interprets the meaning of the metaphor “Copernican turn” as the upgrading of logic, the idea of “transcendental idealism” and discusses the possibility of using the metaphor “Ptolemaic system” to characterize the practical philosophy of Kant.

The article discusses the role of observers in perception of flow of time. It compares two established logics, Branching Space-times and Branching Continuations to a new logic based on Barbour’s timeless approach to physics. The article shows that the introduction of observer based valuation allows for the same evaluation of statements in both temporal and atemporal logics. We show this on the evaluation of statements about the future. Therefore we reach the conclusion that ontological time is not necessary for the (...) evaluation of temporal statements. (shrink)

In line with proponents of 4E cognition, Gallagher [2019] is concerned that many cognitive phenomena are not amenable to decomposition strategies since their very nature is to be constituted extensively. By contrast the received view on causal explanation—the mechanistic account [Craver 2007]—emphasises the necessity for decomposition in explaining natural phenomena and insists on a sharp distinction between causal versus constitutive relations. I propose that removing the requirement that constitutive relations cannot also be causes helps to ease this tension between explanation (...) and Gallagher’s non-decompositional stance, per Leuridan [2012]. Further, I draw on Froese et al.’s [2013] minimal model of social cognition to argue that constitutive relations can and do act as causal difference-makers in the Woodwardian sense [Woodward 2003].

In this paper we want to show how far the early, pre-critical Kant develops a theory of the constitution of space that not only anticipates insights usually attributed to the phenomenological theory of lived space with its emphasis on the constitutively central role of the human lived-body, but which also establishes the foundation for Kant’s Copernican turn according to which space is understood as ‘form of intuition’, implied in the activity of the transcendental subject. The key to understand (...) this role of the body lies in Kant’s understanding of the asymmetrical nature of a pair of hands, which despite being equal in size and structure, remain incongruent counterparts, and thus evade integration into a homogenous and purely self-referential form of space.

There is a widespread misunderstanding in Kant scholarship, partly due to Kant himself, as to his comparison of transcendental philosophy with Copernican revolution in its standard sense as a shift of scientific paradigms. However, there is a reason to think, that this analogy is not correct: what corresponds to it in his system of transcendental philosophy, makes a necessary and basic, but nevertheless a detail of all system, and that which can truly characterize a detail, will be incorrect in (...) relation to the whole. The fundamental in modern Kant scholarship Allison's book«Kant’s TranscendentalIdealism» is chosen as an example of such incorrect characteristic. In my paper I prove, that acceptance of analogy of transcendental philosophy with Copernican revolution leads us to erroneous representation of the former as a kind of anthropocentrism in its phenomenalistic or subjective-idealistic form. Instead of understanding Kant’s revolution as a replacement of one kind of monismby another to what its comparison with Copernican revolution forces, I propose to understand it as a replacement of different kinds of monism, coexisted in Kant’s days in the form of «war of schools», by dualism.

This short blog article presents a solution to the “Scandal of Deduction,” the counter-intuitive finding that no new information is generated by either deduction or deterministic computation. I argue that, since physical computation necessarily involves communications, we cannot expect computation to reduce our uncertainty until it has been completed and its output received as a “message.” This has a number of implications for how we understand semantic theories of information.

Neuroscience made major progress in unravelling the neural basis of mental features like self, consciousness, affect, etc. However, we nevertheless lack what recently has been described as “missing ingredient” or “common currency” in the relationship between neuronal and mental activity. Rather than putting forward yet another theory of the neural basis of mental features, I here suggest a change in our methodological strategy how to approach the brain, that is, our view or vantage point of the brain. Learning from astronomy (...) (Copernicus) and biology (Darwin), I suggest that we may want to change our currently pre-Copernican vantage point from within brain to a post-Copernican vantage point from beyond brain. Such post-Copernican vantage point from beyond brain allows us taking into view that what happens beyond the brain itself, e.g., the world, and how that shapes the brain and its neural activity, e.g., world-brain relation. We then lend empirical support to the world-brain relation by converging it with Karl Friston’s free energy principle that, as we see it, provides a neuro-ecological and therefore post-Copernican view of the brain. That, in turn, allows us taking into view that mental features are shaped by both world and brain and are therefore truly neuro-ecological rather than merely neuronal. This raises the question for the link, e.g., the “missing ingredient” or “common currency” of world brain relation and mental features. Recent empirical evidence suggests that temporo-spatial dynamics may provide such link as it characterizes both the world-brain relation’s free energy and mental features, e.g., their spatiotemporality as described in philosophy. Taken together, I here advocate a change in our methodological strategy on how to approach the brain, that is, a shift from a pre-Copernican vantage point from within brain to a post-Copernican vantage point from beyond brain. The latter allows us taking into view that what happens beyond the brain in the world and how that shapes the brain in such a way that it can yield mental features. This amounts to nothing less than a Copernican turn or revolution in neuroscience akin to the ones in astronomy (Copernicus) and biology (Darwin). (shrink)

Kant’s transcendental philosophy of Kant is the metaphysics of possible experience related to the solution of the [semantic] problem set in his famous letter to M. Hertz (02.21.1772): “What is the ground of the relation of that in us which we call 'representation' to the object?” There are two possible ways to solve it: empiricism and apriorism, – and Kant chooses the second of them, thus making his “Copernican Revolution”. In the Preface to the 2nd ed. Critique Kant correlates (...) his Copernican turn/revolution with "altered method of our way of thinking [in metaphysics]" [BXVIII] and considers it as an analogue of the hypothetico-deductive scientific method of Copernicus – Galileo – Newton. The analysis of structure of the Copernican Revolution shows that it is possible to pick out two vectors: the empirical (from the thing-in-itself to representations) and the noumenal ones (from the transcendental unity of apperception [or transcendental object] to objects of experience). The introduction of an a priori vector (resp. a priori forms) means that Kant's conception is not empirical, but Kant’s keeping empirical vector says that it is compatible with empirical realism [A370–1]. Thus, Kantian transcendentalism is a synthesis of realism (basic level) and transcendental idealism (as a meta-level superstructure above it), whose task is to find out and analyze the transcendental conditions [possibility] of our knowledge of objects.

Against those commentators who consider Kant’s explicit reference to Copernicus’s heliocentric reversal either grossly misleading or simply irrelevant to the revolution in philosophy carried out in the Critique of Pure Reason, it is argued in this paper that Kant’s transcendental idealist inversion of the familiar standpoint of realism and sound common sense fully justifies the talk of a ‘Copernican revolution,’ even if Kant himself never used the expression. It is not just the dominant ‘moving spectator’ motif (or transcendental (...) class='Hi'>turn) of the Preface that has to do with Copernicus; both the immediately following ‘crucial experiment’ motif (on the distinction between appearances and things in themselves) and the ‘critical’ motif (regarding self-knowledge and the possibility of synthetic a priori judgments) confirm the aptness of the Copernican analogy. Still, some commentators have stretched the analogy too far; the final section of the paper attempts to determine just how far it may reasonably be said to go. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Ideas 62.1 (2001) 99-119 [Access article in PDF] Animism and Empiricism: Copernican Physics and the Origins of William Gilbert's Experimental Method John Henry In the second year of this journal's run, way back in 1941, appeared Edgar Zilsel's classic and still widely cited paper on The Origins of William Gilbert's Experimental Method. 1 Focusing on Gilbert's De magnete of 1600, undoubtedly a seminal (...) text in the history of the experimental method, 2 Zilsel argued that Gilbert borrowed his methodology from elite craftsmen, artisans, and other manual workers involved in mining, smelting, smithing, compass making, navigation, sailing, and other activities which involved working with iron or with magnets. 3 On its appearance the paper contributed to a growing and still continuing debate in the history of science about the relative importance of scholars and craftsmen in the origins of modern science. Although Zilsel's general thesis has been critically evaluated in terms of that wider debate, 4 his very specific claims about the [End Page 99] role of elite craftsmen in providing Gilbert with a ready-made experimental method, have never been properly considered. This paper attempts to reassess Zilsel's claims about the origin of Gilbert's experimental method and, in so doing, to arrive at a richer understanding of what Gilbert was trying to do in De magnete and to suggest an alternative source for his experimentalism.The first thing to note about Zilsel's argument is that it had two strands. 5 One of these pointed to actual experimental techniques used by Gilbert and showed that they can all be found in earlier writings on magnets. To be more specific, the techniques in question are to be found either in the thirteenth-century "Letter on the Magnet" written by Petrus Pergrinus or Pierre de Maricourt, first published in 1558, or in The Newe Attractive, a work on the magnetic compass written by a retired mariner, Robert Norman, first published in 1581 but reprinted three times before 1600. 6 The second strand did not involve experiments at all, with one notable exception, but simply implied or suggested that Gilbert's experimental techniques must have been inspired by miners and foundrymen, or navigators and instrument makers. The problem here, as others have objected, 7 is that it is by no means clear that elite craftsmen were engaged in performing experiments in anything like the sense of the word required for the argument to cut any ice. For Zilsel, however, "we cannot doubt that many of [the miners and foundrymen of the period], stimulated to improvements by economic competition, were wont to try new techniques and to observe natural processes." 8 A few sentences later we are told that it is "obvious" that "among such manual labourers there were experimentalists, though experimentalists with practical aims only and without theoretical knowledge." 9 [End Page 100]The philosopher of science at this point might legitimately want to suggest that an experiment is not an experiment unless it is testing a theory, but we do not have to enter into such arguable niceties. 10 We can see that there is something profoundly tendentious in Zilsel's claims simply by reading on. At this point Zilsel mentioned the only experiment specifically referred to in this strand of his argumentation. Quoting Gilbert, Zilsel showed that Gilbert himself must have descended into a mine in order, as Zilsel says, "to verify the hypothesis" that the polarity of a magnet derives from the polarity of the earth: We had a twenty pounds' heavy loadstone dug and hauled out after having first observed and marked its ends in its vein. Then we put the stone in a wooden tub on water, so that it could turn freely. Immediately the surface which had looked to the North in the mine turned itself to the North on the water. 11Zilsel did not make the absurd claim that Gilbert must have seen miners doing this kind of experiment, but he did all he could to...

This paper begins by asking a simple question: can a farmer own and fully utilise precisely five tractors and precisely six tractors at the same time? Of course not. He can own five or he can own six but he cannot own five and six at the same. The answer to this simple question eventually led this author to Alfred Marshall's historically-ignored, linguistically-depicted 'cardboard model' where my goal was to construct a picture based on his written words. More precisely, in (...) this paper the overall goal is to convert Marshall's ('three-dimensional') words into a three-dimensional picture so that the full import of his insight can be appreciated by all readers. After a brief digression necessary to introduce Euclidean three-dimensional space, plus a brief digression to illustrate the pictorial problem with extant theory, the paper turns to Marshall's historically- ignored words. Specifically, it slowly constructs a visual depiction of Marshall's 'cardboard model'. Unfortunately (for all purveyors of extant economic theory), this visual depiction suddenly opens the door to all manner of Copernican heresy. For example, it suddenly becomes obvious that we can join the lowest points on a firm's series of SRAC curves and thereby form its LRAC curve; it suddenly becomes obvious that the firm's series of SRAC curves only appear to intersect because mainstream theory has naively forced our three-dimensional economic reality into a two-dimensional economic sketch; and it suddenly becomes obvious that a two-dimensional sketch is analytically useless because the 'short run' (SR) never turns into the 'long run' (LR) no matter how long we wait.

Although one would not wish to classify Copernicus’ own intentions as belonging to the late-medieval and Renaissance tradition of nominalist philosophy, if we are to turn our consideration to what was responsible for the eventual success of the Copernican Revolution, we must also attend to other features of the dialectical context in relation to which the views of Copernicus and his followers were articulated, interpreted, and evaluated. Accordingly, this paper discusses the significance of the erosion of the Aristotelian (...) prohibition against metabasis to the eventual success of the Copernican Revolution. (shrink)

I raise three objections for Gava’s thesis that the primary task of the Critique of Pure Reason is to develop a doctrine of method for metaphysics, understood as an account of the special kind of unity that a body of cognitions must exhibit to count as a science. First, I argue that this thesis has difficulty accommodating Kant’s concern with explaining the possibility of synthetic a priori judgements. This concern is motivated by a question that is prior to the issue (...) of scientific unity. Second, I argue that the context of the passage in which Kant calls the Critique a treatise on method makes clear that the remark concerns the Copernican Turn. This suggests that the method treated in the book is the procedure required by the Copernican Turn. Third, I dispute Gava’s claim that the idea that confers unity on metaphysics is the cosmopolitan concept of philosophy. (shrink)

Kant's particular philosophical position of transcendental idealism has been a less popular target for recovery than other broadly “Kantian” or “Critical” aspects of his thinking. This chapter outlines Kant's so‐called “Copernican Turn,” which is key to the methodological shift that makes transcendental idealism possible. It discusses the key terminologies of the Kantian project in the First Critique. The chapter then details how these concepts are put to positive use in validating certain traditional metaphysical concepts. It then explores the (...) negative task of Kant's project, which shows that certain other traditional metaphysical concepts are in his view incapable of either vindication or refutation. Finally, it examines how these negative restrictions of Kant's project are themselves geared towards a return to a positive register. Kant introduces or re‐introduces various pairs of notions to explain such achievements: a priori/a posteriori, concept/intuition, cognition/thought, receptive/spontaneous, synthetic/analytic, appearances/things in themselves.

Considerable historiographical controversy surrounds the question of why and how Copernicus decided to overturn the prevailing Earth-centered representation of the heavens. This essay summarizes some key elements of an explanation first laid out in The Copernican Question: Prognostication, Skepticism, and Celestial Order (2011) and subsequently expanded with further evidence in Copernicus and the Astrologers (2016). Copernicus’s defining problem situation is to be found in his involvement in a culture of astrological prognostication during his student days in Bologna (1496–1500). Just (...) before Copernicus’s arrival in the fall of 1496, Giovanni Pico della Mirandola’s attack on the foundations of astrology appeared from a prominent Bologna publisher. This publisher also produced several of the prognostications authored by Domenico Maria di Novara, in whose house Copernicus lodged. Among Pico’s many charges was a claim that astrologers do not agree on the order of the planets. Although the word “astrology” appears only once in Copernicus’s extant writings, it is certain that he was aware of Pico’s account of the astrologers’ disagreements on the matter of planetary order. The Copernican Question sets forth an inference about how and why Copernicus turned to heliocentrism that claims to be not only plausible but also the likeliest to correspond to what actually happened.

This essay examines the significance of Kant's transcendental philosophy by focusing on the central metaphors used in his works. The four metaphors singled out here are those of the Copernican turn, the land of truth and the ocean of illusion, the starry heavens and the moral law, and of perpetual peace. The author emphasizes the strong and the weak points of Kant's philosophy that these metaphors reveals, and argues that these central metaphors work together and point toward the (...) two essential concerns of Kant's entire philosophical opus: an active role of the creative subject in all forms of human experience, and the boundaries of the subject's creativity. Further reflection should not only reveal some other metaphors and their role in Kant's philosophy, but also clarify how he himself understand the nature of metaphors: Are metaphors the expression of our creativity, or of the limitations of our creativity?. Ovaj rad ispituje znacaj Kantove transcendentalne filozofije time sto se usmerava na centralne metafore koriscene u njegovim delima. Cetiri metafore su ovde izdvojene kao najvaznije: kopernikanski obrt, postojbina istine i okean iluzije, zvezdano nebo i moralni zakon, i vecni mir. Autor naglasava jake i slabe stane Kantove filozofije koje razotkrivaju te metafore i argumentise da, uzete zajedno, one ukazuju na dve centralne preokupacije citavog Kantovog filozofskog opusa: aktivna uloga kreativnog subjekta u svim formama ljudskog iskustva, i granice ljudske kreativnosti. Dalja refleksija bi trebalo ne samo da ukaze na neke druge metafore i njihovu ulogu u Kantovoj filozofiji, nego takodje i da razjasni kako je on shvatao samu prirodu metafora: Da H su metafore izraz nase kreativnosti, ili pak izraz granica te kreativnosti?.

THIS PAPER is not a piece of "research"; it simply offers a series of reflections on the transcendental method. It is occasioned by the realization that, while this method is interesting and important in the opinion of some, it can count on little familiarity in the United States. And where philosophers and students of philosophy make the effort, they have great difficulty appreciating transcendental philosophy or understanding its proposals. This difficulty is, as I say, largely circumstantial and due to a (...) lack of familiarity with the relevant works, but, viewed less superficially, it is motivated by a positive affiliation to another philosophical tradition. In fact, the positions of this other tradition are, if largely in a modern guise, the very ones against which transcendental philosophy reacted. This historical relationship has also systematic relevance. In many ways, pre-transcendental positions seem to have priority: we need only think of formal logic, certain basic stances in empiricist epistemology, common sense. Accordingly, the subjective difficulty of philosophers and students of such persuasions can be treated "objectively," as the difficulty of ever establishing arguments for the transcendental turn or for what Kant calls the "Copernican revolution." Transcendental philosophy must provide arguments, so it seems, on the pre-transcendental level to establish the transcendental position. Further, supposing this problem can be overcome, there is the genuine difficulty of understanding what the transcendental theory actually says and in what way it does its job. And lastly, supposing we find that it lives up to its program, there may still be difficulty with certain implications such that philosophers and students take refuge in non-transcendental positions rather than calling for improvements of transcendental philosophy. In this paper we cannot, of course, fully discuss to what extent the transcendental position can take care of its critics. The paper is mainly concerned with the difficulty of access or introductory argument to transcendental philosophy. (shrink)

The Anthropocene is heralded as a new epoch distinguishing itself from all foregoing eons in the history of the Earth. It is characterized by the overarching importance of the human species in a number of respects, but also by the recognition of human dependence and precariousness. A critical human turn affecting the human condition is still in the process of arriving in the wake of an initial Copernican Revolution and Kant's ensuing second Copernican Counter-revolution. Within this landscape, (...) issues concerning the human - its finitude, responsiveness, responsibility, maturity, auto-affection and relationship to itself - appear rephrased and re-accentuated as decisive probing questions. In this book Sverre Raffnsøe explores how the change has ramifications for the kinds of knowledge that can be acquired concerning human beings and for the human sciences as a study of human existential beings in the world.

Kant's influence on the history of philosophy is vast and protean. The transcendental turn denotes one of its most important forms, defined by the notion that Kant's deepest insight should not be identified with any specific epistemological or metaphysical doctrine, but rather concerns the fundamental standpoint and terms of reference of philosophical enquiry. To take the transcendental turn is not to endorse any of Kant's specific teachings, but to accept that the Copernican revolution announced in the Preface (...) of the Critique of Pure Reason sets philosophy on a new footing and constitutes the proper starting point of philosophical reflection.In this volume a team of leading philosophers explore the concept of the transcendental as it developed through history, focusing on approaches to the transcendental project by Kant, Fichte, Hegel, Nietzsche, Husserl, Heidegger, Merleau-Ponty, and Bernard Williams. By giving systematic shape to historical material, the volume provides a unique resource for systematic reflection on transcendental philosophy. (shrink)

Reading List Essay Questions.

KANT USED the metaphor of a Copernican revolution for that inversion according to which our philosophic principles are to be drawn from the character of the knower—from the faculties of the human mind—rather than from the object to be known. We might say that there may be a further such inversion, a second Copernican Revolution in philosophy, so to speak. By this turn, both the things to be known and the determinations of the knower might be thought (...) to revolve around language. From this stance, we may be led to seek our philosophic principles in our habitual or our necessary modes of expression. Linguistic capacities would thus become the sieve—or the veil, or the limiting distortion—through which, or by means of which, all else is determined. Among them will be found reality and such objects of knowledge as may be formulated in scientific fashion. And also such psychic powers and conceptual patterns as are susceptible to human communication. Were we to undertake such a succeeding revolution, language itself would become the center around which must turn both our real world and our minds themselves. (shrink)

This paper examines Slavoj Zizek’s reading of Immanuel Kant. Its undergirding argument is that Zizek’s work as a whole- up to and including his politically radical statements, which have become more and more prominent since 1997- is conceivable as a project in the rereading of the Kantian ‘Copernican Revolution’ via Lacanian psychoanalysis. Critics now agree that Zizek’s orienting aim is to write a philosophy of politics, as more recent texts, like The Ticklish Subject make clear. (Kay, 2003; Sharpe, 2004; (...) Dean 2006) If Zizek’s philosophy is ultimately a philosophy of politics, however, Zizek’s political philosophy is grounded in a wider post or ‘neo’-Kantian philosophy of subjectivity.
The essay has three major parts. Part I gives Zizek’s reading of Kant on the subject of apperception. Part II recounts Zizek’s pivotal reading of Kant on the sublime, which he ties closely to the problematics of the ‘Transcendental Dialectic’ of the first Critique. Part III then examines Zizek’s conception of subjectivity in terms of the faculties (and especially the faculty of imagination) that Kant argues are involved in the transcendental constitution of objects in the first half of The Critique of Pure Reason.
In the Conclusion, the force of the paper’s subtitle—‘Politicising the Transcendental Turn’—will become manifest. I lay out three principles of Zizek’s ‘neoKantian/Hegelian’ ontology. These also make clear how his philosophy of political agency is grounded in this apparently suprapolitical or solely philosophical reading of Kant.

A genuine Copernican turn in Kantian and Marxist theory and practice.

Kant’s Copernican turn has been the subject of intense philosophical debate because of the central role it plays in his transcendental philosophy. The analogy that Kant depicts between his own proposal and Copernicus’s has received many and varied interpretations that focus either on Copernicus’s heliocentrism and scientific procedure or on the experimental character of Kant’s endeavor. In this paper, I gather and review some of these interpretations, especially those that have ap­peared since the beginning of the twentieth century, (...) to show the many disparate and often contradictory stances that the Copernican turn has elicited. Despite the controversies between the different interpretations, they all are follow ups and reinventions of the single philosophical event named the Copernican turn. This common origin allows me to advance a narrative that portrays that event as an experiment, following Hans-Jörg Rheinberger’s philosophy of experimentation. My position does not entail that an experiment such as Kant’s conforms to what a scientific experiment is, although their histories could be narrated using a similar conceptual framework. In the end, my argument advances an experimental reading of the history of philosophy. (shrink)

Open peer commentary on the article “Cybernetics, Reflexivity and Second-Order Science” by Louis H. Kauffman. Upshot: The commentary focuses on some similarities between Kauffman’s remarks on reflective, self-referential science, Kant’s “Copernican turn” and the historicization of knowledge within “continental philosophy.”.

This volume, developing research on a theme that has been addressed very little, deals with the relation between the discovery of a priori feelings and emotions in Kant’s Critique of Practical Reason and the «Preface» to the second edition of Kant’s Critique of Pure Reason in which he announces a revolution in the way of thinking. In Chapter One, I treat some aspects of the relation between the role of feel-ings and the Newtonian model in some of Kant’s pre-critical writings. (...) Chapter II will analyze the moral theory of the Critique of Pure Reason in order to show that in this work moral feeling is always conceived of as an a posteriori and em-pirical element. Chapter Three is devoted to the examination of the concept of a revolution in Kant’s way of thinking and of its relationship to the Newtonian model in the first Critique. Although the term ‘Copernican turn’ [kopernikanische Wende] is usually used, it will be shown that this expression emphasizes only one aspect of the change that Kant achieves. While both Kepler and Newton have given apo-dictic certainty to the hypothetical thoughts of Copernicus, Kant will transform the hypothesis proposed in the first Critique into apodictic certainty. The only possibility for demonstrating the transcendental and hypothetical ideals of free-dom, God and immortality rests, for Kant, with the objective reality of moral consciousness. Hence, Kant will become the Newton of the thing in themselves. In Chapter Four, I address the theme of feelings and emotions in the «Dia-lectic» and the «Doctrine of Method» sections of the Critique of Practical Rea-son. This will prove that the passage from hypothesis to apodictic certainty, from Copernicus to Newton, both in speculative and in moral philosophy is strictly connected to the discovery of a priori emotions and feelings. Respect, contentment, interest, effort, need, and propensity of reason are the grounds of the proof of the objective reality of moral consciousness, of the primacy of prac-tical reason, of moral faith, and of education to the moral sublime. In some cases this will be illustrated by highlighting the relation between Kant’s theory and the doctrines of his sources, such as Hume, Milton, Montaigne, Rousseau, Sweden-borg, and Virgil.

The consensus view in the literature is that, according to Kant, definitions in philosophy are impossible. While this is true prior to the advent of transcendental philosophy, I argue that with Kant's Copernican Turn definitions of some philosophical concepts, the categories, become possible. Along the way I discuss issues like why Kant introduces the ‘Analytic of Concepts’ as an analysis of the understanding, how this faculty, as the faculty for judging, provides the principle for the complete exhibition of (...) the categories, how the pure categories relate to the schematized categories, and how the latter can be used on empirical objects.

In the Club of Rome report Come on! Capitalism, Short-Termism, Population and the Destruction of the Planet (2018) Kant, along with other “old” Enlighteners, is presented as the father of a world-view which led to the destabilisation of the environment in which humanity exists. The authors of the report argue that the “old Enlightenment” with its individualism, faith in the market and a consumerist attitude to nature should be scrapped. I maintain that this assessment of Kant’s philosophy is groundless and (...) that his ideas allow us both to conduct a more profound diagnosis of the crisis and to propose a more solidly founded strategy of overcoming it. First, I sum up the position of the authors concerning the loss of sustainability of development which they attribute to the philosophy of Enlightenment. Next, I outline the history and content of the notion of “sustainable development” and offer an analysis of the sources of progressivist commitment to the conquest of nature which lie outside Modern Times in the idea of the “cultural mandate”. Then I present the Kantian diagnosis of the causes of the crisis which attributes it to humankind’s failure to “mature”. I compare the idea of “the full world” formulated by the authors of the report with the idea of the “the world come of age” and their diagnosis of “capitalism — short-termism — depletion of resources” with the Kantian assessment of the attempts to escape from the predicaments of the present into the past or the future. I draw attention to Kant’s solutions to some of the specific problems indicated in the report. Instead of the strategy of “return of the cultural mandate”, proposed at this time by the authors of the report, the Kant­ian answer to the crisis is a “Copernican turn” and re-direction of the cultivating effort to the inner moral development of the human being.

This essay follows the strategy of Kant’s »Copernican Turn« bearing pragmatic features. It tries to show that this strategy is unjustified, that it forms theses about the character of reality and that it cannot provide the basis for »antirealism« developed – following Kant – by Richard Rorty. These problems indicate deficiencies of nominalist empiricism which Kant hasn’t managed to refute, and which today calls for further critical analyses of experience. Phenomenology in this context proves to be of particular (...) importance. (shrink)

Arguably, the most promising and compelling route to demonstrating the significance of Hegel’s thought to contemporary philosophy has been the series of recent readings that construe Hegel as continuing and completing Kant’s Copernican turn. Paul Redding explicitly locates his interpretation within this program, seeing the hermeneutic dimension of Hegel’s thought as providing for the possibility of continuing the Kantian project. Kant’s Copernican turn can be loosely stated as the procedure of reflectively uncovering unexperienced conditions of experience (...) that contribute to the nature of experience in ways that require its further re-determination and re-description. What a hemeneutic take on this reflective procedure adds is that foremost among those conditions are contexts of intersubjective or dialogical relations—structures of recognition. While perhaps disappointing to anyone interested in the problem of textual interpretation, there is finally nothing more to Redding’s account of Hegel’s “hermeneutics” than the establishing of recognitive structures as forming the ultimate horizon of human experience. I take Redding’s relentless tracking of the problem of recognition to be one of his book’s virtues. (shrink)

This paper takes a fresh look at a classical theme in philosophical scholarship, the meaning of transcendental idealism, by contrasting Kant's and Husserl's versions thereof. I present Kant's transcendental idealism as a theory distinguishing between the world as in-itself and as given to the experiencing human being. This reconstruction provides the backdrop for Husserl's transcendental phenomenology as a brand of transcendental idealism expanding on Kant: Through the phenomenological reduction Husserl universalizes Kant's transcendental philosophy to an eidetic science of subjectivity. He (...) thereby furnishes a new sense of transcendental philosophy, rephrases the 'quid iuris?,' and provides a new conception of the thing-in-itself. What needs to be clarified is not exclusively the possibility of a priori cognition, but instead, starting much lower, the validity of objects that give themselves in experience. The thing-in-itself is not an unknowable object, but the idea of the object in all possible appearances experienced at once. In all these innovations Husserl remains committed to the basic sense of Kant’s Copernican Turn. I end with some comments on how both Kant and Husserl view the relation between theoretical and moral philosophy. (shrink)

In der Medizin vollzieht sich im 19. Jahrhundert eine kopernikanische Wende: Die Zellulartheorie wird entwickelt. Heute ist uns vollig selbstverstandlich, dass der menschliche Korper aus Zellen besteht, die seine Struktur und Funktion bestimmen. Doch diese Lehre bestimmt seit gerade einmal 150 Jahren das medizinische Denken und hat Theorien abgelost, welche unvorstellbare 2.000 Jahre Geltung besassen. Diesen Wandel interpretiert die Autorin als Paradigmawechsel und verfolgt ihn in den Werken deutscher, englischer und franzosischer Arzte des 18. und 19. Jahrhunderts. Sie beleuchtet den (...) Einfluss der Philosophie, insbesondere die Auswirkungen der Ideen Kants und Schellings. Die Studie zu den philosophischen Grundlagen der modernen Medizin richtet sich an Philosophen, Wissenschaftshistoriker und Arzte. In the 19th century, a Copernican turn took place in medicine with the development of the cell theory. We take it completely for granted today that the human body is made up of cells which determine its structure and its function. But this doctrine has only been defining medical thinking for 150 years and it replaced theories which had been valid for an inconceivable 2000 years. The author interprets this transition as a paradigm shift, and she explores it in the works of German, English and French doctors in the 18th and 19th century. She sheds light on the influence of philosophy, in particular the impact of Kans and Schellings ideas. This study of the philosophical foundations of modern medicine is addressed to philosophers, science historians and medical physicians. (shrink)

The article is a short presentation and critical evaluation of the main aspects of Kant’s theoretical and practical philosophy. It focuses on ontological consequences of the so-called Copernican turn that places man in a self-created, phenomenal world, cutting off any hope for his contact with the transcendent reality, independent of man’s cognition. The only escape from this danger of the subjectification of reality is, unjustly criticized, Kant’s acknowledgment of Ding an sich. In the area of practical philosophy, Kant’s (...) ethics of categorical imperative, of good will and the fact of freedom, is an interesting but indefensible project of formal and autonomic ethics that, unfortunately, due to its elitist conclusions cannot fulfil the task of teaching morality. In the light of development in cultural anthropology and hermeneutical philosophy of life, Kant’s position needs to be significantly updated. (shrink)

My aim is to demonstrate the specificities and differences between transcendental deduction of concepts and deduction of the fundamental principles of pure practical reason in Kant’s metaphysics. First of all it is necessary to examine Kant’s attitude to the metaphysics of his time and the problem of its new justification. Kant in his philosophy explicated not only the theoretical world of cognition, but also the practical world of freedom. Accordingly, the fundamental means of proving metaphysics’ claims are the deduction of (...) pure concepts of understanding and the deduction of the principles of pure practical reason. The underlying premises of the Kantian project of reviving metaphysics, “the Copernican Turn”, the critical methods and basic principles of transcendental idealism also provide the methodological basis of transcendental deduction, a new method of proving the claims of metaphysics in various spheres of human being. Proceeding from the above, I analyse the essence, structure and the peculiarities as well as the differences between the deduction of experience and the deduction of freedom. I single out the following features of the two types of deduction. First, theoretical use of reason is aimed at objects while practical reason is aimed at noumena, the foundations of will and freedom. Second, the transcendental deduction of space and time, as well as the deduction of categories, is preceded by transcendental reduction, which is absent in the deduction of freedom. Third, Kant orients the methodological movement of deductions in opposite directions. Theoretical deduction proceeds from pure forms of sensible intuition to concepts of understanding and thence to fundamental principles. Practical deduction proceeds from a priori principles to the concepts of the metaphysics of morals and thence to moral feelings. Fourth, deduction in the theoretical sphere forbids speculative reason to go beyond experience. Practical deduction has pointed to the intelligible world and has proved its “legitimacy”. (shrink)

This journey shall provide the reader with a simple, though complete, guide to Leibniz’s metaphysics, incidentally preventing him or her from common errors. I will start with unfolding Leibniz’s definition of a simple substance as a free acting individual substance, which, in doing so, constitutes its complete concept. This latter contains everything that happens to the individual substance, a process taking place in God’s mind by forming the possibilities as combinations of his attributes before his decision to create the best (...) world. The totality of possibilities is divided through the compatibility relation into possible worlds. A world is a collection of all compatible individual substances. God creates the best among all possible worlds. The journey will enlighten the reader on Leibniz’s technical distinction between “possible” and “contingent”. In short, “possible” is defined by Leibniz in logical terms, as what is contradiction-free. “Contingent” is something that is, but might have been not. Just the fact that the non-being of contingent things remains possible saves Leibniz from Descartes’ and Spinoza’s determinism. (shrink)

We argue that Kant advocates existence dualism in a largely Cartesian vein. In such a dualism, there are two basic kinds of existence or ways of being: I-existence and categorial existence. I-existence denotes my existence, while categorial existence denotes, basically, the existence of ordinary things. First, we show how the route to existence is fundamentally different in the two cases. Then we ask whether they also indicate two ontologically distinct kinds and argue that I-existence should be regarded as the fundamental (...) kind of existence in any case. One important consequence of this is that I-existence stands outside the Kantian conditions of experience, being the one un-Copernican element left intact after Kant’s Copernican turn. (shrink)

Husserl’s lifelong interest in Kant eventually becomes a preoccupation in his later years when he finds his phenomenology in competition with Neokantianism for the title of transcendental philosophy. Some issues that Husserl is concerned with in Kant are bound up with the works of Lambert. Kant believed that the role played by principles of sensibility in metaphysics should be determined by a “general phenomenology” on which Lambert had written. Kant initially believed that man is capable only of symbolic cognition, not (...) intellectual intuition. Lambert saw an increasing need in mathematics for symbolic cognition as exemplified in his proofs of the irrationality of π and e. Kant takes from Leibniz and Lambert an unrestricted notion of construction, allowing him to view mathematics as constructing its concepts in intuition, while Lambert’s proofs convince him that all mathematical problems are eventually solvable. Husserl criticizes Kant’s intuitionism for its inadequate accommodation of meaning to intuition, which he redresses with his theory of categorial intuition. This may improve on Kant’s intuition of the axiom of parallels but not so clearly on his spatial intuition. Husserl opposes Kant’s view of space as the form of outer intuition with his own view of it as the form of things. Husserl’s exploration of the geometry of visual space, which involves his earliest uses of epoché and reduction, converges however with Hilbert’s logical analysis of Kantian spatial intuition in leading to Euclidean spatial judgments. Hilbert’s analysis leads him to affirm the solvability of all well posed mathematical problems, a thesis complicated by the outbreak of logical paradoxes. Untroubled by such paradoxes, Husserl develops a supramathematics of all possible deductive systems whose completeness implicitly would also provide solutions of all such problems. Husserl’s full transcendental turn coincides with his realization that in effecting his Copernican turn, Kant was really the first to detect the “secret longing” of modern philosophy for a phenomenological clarification of being. Husserl now finds that Kant’s transcendental deductions presuppose a pure ego not adequately analyzed by Kant that survives the phenomenological reduction. Husserl’s idealism leads him to develop his own intuitionism, which adds to Kant’s, a “method of clarification” of mathematical concepts intended to clarify difficult impossibility proofs, but neither Husserl nor Kant base arithmetic on time. Husserl’s critique of the room left in Kant’s idealism, for things in themselves, leads to his own monadological solution of the problem of intersubjectivity. Husserl’s final judgment on Kant is that his form of transcendental idealism did not enable him to achieve absolute subjectivity through a genuine transcendental reduction. (shrink)

After the completion of I. Kant’s “Copernican” turn in metaphysics, all subsequent European philosophy to one degree or another was under his influence. The purpose of the article is to consider the reception and transformation of the Kantian theoretical philosophy by the Marburg school of neo-Kantianism. It is necessary to analyze the reasons for H. Cohen's and P. Natorp’s interpretation of Kant's criticism. To do this, one should consider (i) internalist and (ii) externalist factors in the formation of (...) the Marburg School. Neo-Kantianism, on the one hand, emerged as a response to materialism, naturalism, and post-Kantian German idealism. In addition, the Marburg School was strongly influenced by the change in the scientific paradigm in mathematical natural science at the end of the 19th century. The justification by the Marburgers of Kant’s a priori doctrine presupposed thematization, first of all, of: a) purity of thought; b) systematic unity of thought and experience; c) the orientation of philosophy to the “fact of science”; d) transcendental method. As a result, the Marburg School interpreted the Kantian concept of the unity of consciousness; abandoned the principle of synthetic (real) unity of consciousness in favor of systematic (logical) unity; substantiated the purity of scientific thinking; put forward the requirement of orientation of philosophy to the “fact of science”; developed the concept of the origin of thinking (Ursprung); abandoned the idea of “givenness” of the subject of knowledge and proved its “assignment”; changed the understanding of the essence and functions of the transcendental method; put forward the concept of thinking as “generation” (“production”); formulated a new understanding a priori. The changes that took place in the 19th century in philosophy, mathematical natural science and mathematical sciences led to a sharp activation of constructivism. It can be concluded that Kant’s epistemological paradigm was realistic constructivism. Pure constructivism became the paradigm of the Marburg School. (shrink)

A precursor to the hard problem of consciousness confronts nihilism. Like physicalism, nihilism collides with the first-personal fact of what perception and action are like. Unless this problem is solved, nature’s inclusion of conscious experience will remain, as Chalmers warns the physicalist, an “unanswered question” and, as Jacobi chides the nihilist, “completely inexplicable". One advantage of Kant’s Copernican turn is to dismiss the question that imposes this hard problem. We need not ask how nature is accompanied by the (...) first-person standpoint because “I think” is an apperceptive form of thinking that must be able to accompany any cognition of nature. Kant’s formal conception of apperception worries Fichte in his Nova Methodo lectures. This conception arguably cannot exhaust the ground of experience, for it does not show why we posit objects “at all". For Fichte, it is our agency that first opens a world of objects, viz., as subjects, means, ends, and obstacles. In what follows, I argue that, for Fichte, the I poses no hard problem because it collides exclusively with nihilistic views like Spinozism, which are refuted by a properly transcendental idealist conception of apperception, according to which the first-person standpoint is the absolute ground of our experience of nature. If transcendental idealism refutes nihilism, nature is no more explicable than that there is something it is like for me to perceive and act. In Section 1, I show why Kantian apperception is necessary for possible experience. In Section 2, I reconstruct Fichte’s argument that a modified conception of apperception refutes guises of nihilism, thereby solving the hard problem of consciousness. In Section 3, I suggest that transcendental idealism undermines Chalmers’ proposed solution to and Dennett’s dismissal of this problem. (shrink)
