What makes a government legitimate? Arthur Isak Applbaum rigorously argues that the greatest threat to democracies today is not loss of basic rights or despotism. It is the tyranny of unreason: domination of citizens by incoherent, inconstant, incontinent rulers. A government that cannot govern itself cannot legitimately govern others.

Few philosophers have left a legacy like that of Gottfried Wilhelm Leibniz. He has been credited not only with inventing the differential calculus, but also with anticipating the basic ideas of modern logic, information science, and fractal geometry. He made important contributions to such diverse fields as jurisprudence, geology and etymology, while sketching designs for calculating machines, wind pumps, and submarines. But the common presentation of his philosophy as a kind of unworldly idealism is at odds with all this bustling (...) practical activity. In this book Richard. T. W. Arthur offers a fresh reading of Leibniz’s philosophy, clearly situating it in its scientific, political and theological contexts. He argues that Leibniz aimed to provide an improved foundation for the mechanical philosophy based on a new kind of universal language. His contributions to natural philosophy are an integral part of this programme, which his metaphysics, dynamics and organic philosophy were designed to support. Rather than denying that substances really exist in space and time, as the idealist reading proposes, Leibniz sought to provide a deeper understanding of substance and body, and a correct understanding of space as an order of situations and time as an order of successive things. This lively and approachable book will appeal to students of philosophy, as well as anyone seeking a stimulating introduction to Leibniz's thought and its continuing relevance. (shrink)

It is commonly held that there is no place for the 'now’ in physics, and also that the passing of time is something subjective, having to do with the way reality is experienced but not with the way reality is. Indeed, the majority of modern theoretical physicists and philosophers of physics contend that the passing of time is incompatible with modern physical theory, and excluded in a fundamental description of physical reality. This book provides a forceful rebuttal of such claims. (...) In successive chapters the author explains the historical precedents of the modern opposition to time flow, giving careful expositions of matters relevant to becoming in classical physics, the special and general theories of relativity, and quantum theory, without presupposing prior expertise in these subjects. Analysing the arguments of thinkers ranging from Aristotle, Russell, and Bergson to the proponents of quantum gravity, he contends that the passage of time, understood as a local becoming of events out of those in their past at varying rates, is not only compatible with the theories of modern physics, but implicit in them.

In this new work, Richard T. W. Arthur offers a fresh interpretation of Leibniz's theory of substance. He goes against a long trend of idealistic interpretations of Leibniz's thought by instead taking seriously Leibniz's claim of introducing monads to solve the problem of the composition of matter and motion.

Fundamental Theory has been called an "unfinished symphony" and "a challenge to the musicians among natural philosophers of the future". This book, written in 1944 but left unfinished because Eddington died too soon, proved to be his final effort at a vision for harmonization of quantum physics and relativity. The work is less connected and internally integrated than 'Protons and Electrons' while representing a later point in the author's thought arc. The really interested student should read both books together.The physical (...) and mathematical reasoning are very deep, but it is possible to enjoy much of the flavor of the book even without following everything. The tidbits given below illustrate Eddington's beautiful and mellifluous English style. This edition contains a clickable table of contents and some interesting illustrations.WARNING: Due to the complexity of the mathematical typesetting, the only way to reproduce this book has been as a series of scanned page images. We believe this work is scientifically and culturally important, and despite a few imperfections and the inevitably small print, have brought it back into print as part of our continuing commitment to the preservation of Eddington's work. On a portable electronic reader the pages come out pretty small, but they are legible. On a desktop computer running the Amazon app, they are perfectly fine. We appreciate your understanding, and hope you enjoy this valuable book.TIDBITS:The number of protons and electrons in the universe would, in itself, be merely a matter of idle curiosity. But N has a more general significance as a fundamental constant which enters into many physical formulae. Its special interpretation as the number of particles in the universe arises in the following way. If we consider a distribution of hydrogen in equilibrium at zero temperature, the presence of the matter produces a curvature of space, and the curvature causes the space to close when the number of particles contained in it reaches a certain total; that number is N. The present investigation seeks to determine N directly from the principles of measurement. We have to show, not that there are N particles in the universe, but that anyone who accepts certain elementary principles of measurement must, if he is consistent, think there are. We have to express in mathematical symbolism what we think we are doing when we measure things; for if we had no conception of what we were doing, the results of the measurements would not persuade us to believe anything in particular. All our results are derived from the condition that the conceptual interpretation which we place on the results of measurement must be consistent with our conceptual interpretation of the process of measurement.If we play about with a pin and a meter standard, we do not become aware of any number in particular unless the standard has been graduated, or unless we use a process of displacement which we interpret as adding pin-extensions. The fact is that, although measurement is primarily a process involving four entities, the conceptual interpretation of measurement postulates in addition the existence (in the structure contemplated) as something referred to as Z. The existence of Z is the condition that makes graduation an exact concept. In the actual universe there exists a basis which is uniform to a very high approximation, and this serves for almost all purposes; but to the much higher approximation required in the calculation of N the ideal exact basis of uniformity does not exist. The finitude of N is, in fact, the cause of the failure of the approximation.It must be remembered that we are now working to what would ordinarily be considered a fantastically high approximation. For ordinary purposes a measurable has 16 eigenvalues; but under the super-magnification here employed (which is not content to overlook 1 part in 10E39) there is a fine structure which splits each of them into 16 components.

It is well known that Leibniz advocated the actual infinite, but that he did not admit infinite collections or infinite numbers. But his assimilation of this account to the scholastic notion of the syncategorematic infinite has given rise to controversy. A common interpretation is that in mathematics Leibniz’s syncategorematic infinite is identical with the Aristotelian potential infinite, so that it applies only to ideal entities, and is therefore distinct from the actual infinite that applies to the actual world. Against this, (...) I argue in this paper that Leibniz’s actual infinite, understood syncategorematically, applies to any entities that are actually infinite in multitude, whether numbers, actual parts of matter, or monads. It signifies that there are more of them than can be assigned a number, but that there is no infinite number or collection of them, which notion involves a contradiction. Similarly, to say that a magnitude is actually infinitely small in the syncategorematic sense is to say that no matter how small a magnitude one takes, there is a smaller, but there are no actual infinitesimals. In geometry one may calculate with expressions apparently denoting such entities, on the understanding that they are fictions, standing for variable magnitudes that can be made arbitrarily small, so as to produce demonstrations that there is no error in the resulting expressions.

Originally published in 1940, this book by famous Plotinus scholar Arthur Hilary Armstrong assesses how the philosopher's hierarchy of reality fits into the wider universal order, and how the historical and philosophical tradition gave rise to Plotinus' own philosophies. Armstrong also supplies a bibliography broken down by topic for those who wish to pursue any aspect of the text in greater depth. This book will be of value to anyone with an interest in Plotinus, Neoplatonism and in the pagan (...) roots of Christian philosophy. (shrink)

Romanticism fabricated a poet of vast oracular powers largely from superstitious notions and suspicious philosophies which the Renaissance had gathered up somewhat by chance with the rational part of the Graeco-Roman legacy. The model was surely an imposture and, historically considered, a scandal. Seer, sage, prophet, mage—the pretensions varied, but all were titles to transcendent disclosure in times increasingly committed, at least officially, to a unified scientific view. That the poet could be confirmed to any degree in this anachronistic role (...) was probably owing to the circumstance that the general cultural reflex following the Enlightenment reawakened widespread interest in those dark and excluded passages of the human spirit which mystics and seers were thought to frequent. Poets who pretended to voyance benefited from the muffled but persistent rumor of profound mysteries accessible to the high priests of Kabbala and the Corpus Hermeticum, to Illuminists, Rosicrucians, and Neopythagoreans. Western Europe had never ceased to acknowledge, even in such unlikely periods as the later Middle Ages, the aboriginal priestly and prophetic functions of the poet; but romanticism contrived—out of occultism and neoplatonism, antirationalism and anticlassicism—such a warrant for unabashed oracular saying as Antiquity had scarcely imagined. While perhaps none of the romantic was actually prepared to grant the poet his ancient powers in full measure, few seemed inclined to diminish the stature of the heroic abstraction, who symbolically contested the claims of naturalism and positivism.

Neste artigo apresentamos uma tradução e discussão de uma carta do filósofo Leibniz (1646-1716), na qual ele discute ações para o aperfeiçoamento da medicina. A importância e atualidade desta carta consiste em propor ações públicas de controle de epidemias pelo estado, como também, discute o uso de medicação pela medicina para controle das epidemias. No primeiro momento, explicamos a importância da publicação desta carta, destinada a Germain Brice, no Journal des Savants. No segundo momento apresentamos a tradução do texto, onde (...) ele sugere a coleta de informações para ajudar na contenção da disseminação das doenças epidemiológicas. Essa é uma sugestão da qual alguns governos modernos poderiam se beneficiar. No mesmo texto, Leibniz também faz referência ao tratamento de uma pandemia com uma substância considerada estranha.

Dieses Neue liegt fur das vorliegende Buch nicht sosehr in seiner grundsatzlichen Einstellung, die sich von der J 0 r dan s kaum unterscheidet, als im Versuch, die fur die neue Physik entscheidcn­ den Ideen unter Verzicht auf jede Mathematik so Zu entwickeln, daB auch der Nichtfachmann sich uber sie ein klares Urteil zu bilden vermag und sie nicht einfach auf guten Glauben hinnehmen muB.

We show that the theories “ZFC \ There is a supercompact cardinal” and “ZFC \ There is a supercompact cardinal \ Level by level inequivalence between strong compactness and supercompactness holds” are equiconsistent.

Cannabis use in some individuals can meaningfully introduce de novo risk for the initiation of opioid use and development of opioid use disorder. These risks may be particularly high during adolescence when cannabis use may disrupt critical periods of neurodevelopment. Current research studying the combination of genetic and environmental factors involved in substance use disorders is poorly understood. More research is needed, particularly to identify which adolescents are most at risk and to develop effective interventions addressing contributing factors such as (...) trauma and psychiatric comorbidity.

In this essay, I trace the motif of abandonment that runs through the ethics of Simone Weil. In doing so, as a conceptual lens, I make use of Giorgio Agamben’s concept of abandonment. Taking my cue from Weil’s hesitations concerning baptism, I examine her stance as a case of either sacrifice or exception, of ambiguity or indifference. Subsequently, I use Weil’s hesitations to examine an interconnected sequence of soteriology and metaphysics, following Church and potentiality, World and actuality, and The Kingdom (...) and contingency. This allows me to explore the themes of writing and life. A crucial role is reserved for the Parable of the Sower, and how it discriminates between the saved and the damned. (shrink)
