This paper empirically investigates one aspect of the folk concept of time by testing how the presence or absence of directedness impacts judgements about whether there is time in a world. Experiment 1 found that dynamists, showed significantly higher levels of agreement that there is time in dynamically directed worlds than in non-dynamical non-directed worlds. Comparing our results to those we describe in Latham et al., we report that while ~ 70% of dynamists say there is time in B-theory worlds, (...) only ~ 45% say there is time in C-theory worlds. Thus, while the presence of directedness makes dynamists more inclined to say there is time in a world, a substantial subpopulation of dynamists judge that there is time in non-directed worlds. By contrast, a majority of non-dynamists judged that there was time in both growing block worlds and C-theory worlds, with no significant differences between the means. Experiment 2 found that when participants are only presented with non-dynamical worlds—namely, a directed world and a non-directed world—they report significantly higher levels of agreement that there is time in B-theory worlds. However, the majority of participants still judge that there is time in C-theory worlds. We conclude that while the presence of directedness bolsters judgements that there is time, most people do not judge it to be necessary for time. (shrink)

Recent research (Latham, Miller and Norton, forthcoming) reveals that a majority of people represent actual time as dynamical. But do they, as suggested by McTaggart and Gödel, represent time as essentially dynamical? This paper distinguishes three interrelated questions. We ask (a) whether the folk representation of time is sensitive or insensitive: i.e., does what satisfies the folk representation of time in counterfactual worlds depend on what satisfies it actually—sensitive—or does is not depend on what satisfies it actually—insensitive, and (b) (...) do those who represent actual time as dynamical, represent time in all possible worlds as dynamical—what we call insensitive dynamism—or do they represent time in all possible worlds as dynamical only conditional on the actual world in fact being dynamical—what we call sensitive dynamism and (c) do dynamists and non-dynamists deploy two different representations of time, or deploy the same representation, but disagree about what actually satisfies that representation? We found no evidence that the folk representation of time is sensitive, or that the folk representation of time is essentially dynamical in either sense, though we did find evidence of a shared representation, on which dynamical features are sufficient, but not necessary, for time.

This paper investigates the connection between temporal attitudes (attitudes characterised by a concern (or lack thereof) about future and past events), beliefs about temporal ontology (beliefs about the existence of future and past events) and temporal preferences (preferences regarding where in time events are located). Our aim is to probe the connection between these preferences, attitudes, and beliefs, in order to better evaluate the normative status of these preferences. We investigate the hypothesis that there is a three-way association between (a) (...) being present-biased (that is, preferring that positive events are located in the present, and negative events are located in the non-present), (b) believing that past and future events do not exist and (c) tending to have present-focused rather than non-present-focused temporal attitudes. We find no such association. This suggests that insofar as temporal preferences and temporal attitudes are connected to the ways we represent time, they are not connected to the ways we represent temporal ontology; rather, they are more likely connected to the ways we represent relative movement in, or of, time. This has important consequences for, first, explaining why we exhibit these preferences and, second, for their normative evaluation. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:More Evidence that Hume Wrote the Abstract David Fate Norton In the preceding paper, David Raynor has offered several reasons for discounting J. O. Nelson's unfounded claim that Adam Smith was the author ofAn Abstract of..."A Treatise ofHuman Nature." Prior to the discovery ofa copy ofthis work, it may have been plausible to suppose that the Abstract was written by someone other than Hume, but the internal evidence (...) ofthe pamphlet is so strongly in favour of Humean authorship that not even Nelson can bring himself to question this evidence—although he now chooses to ignore it. Given that Nelson's argument rests on the far from compelling assumption that in 1740 there were two and onlytwoMr. Smith's ofwhom Humehadknowledge and whomayhave had an interest in writingor publishing philosophy, it is especially useful to have William Smith, publisher of the Bibliothèque raisonnée, brought again to our attention, and especially since it is obvious that a copy of the Abstract had been sent to that journal prior to the pubUcation ofthe review ofthe Treatise published there in the spring of1740.1 In short, Raynor nicely shows why Keynes and Sraffa were wrong to suppose that Hume, Hutcheson and John Noon were all involved in a conspiracy to undercut Noon's interest by publishing an Irish edition ofthe Treatise2 and why Nelson is wrong to suppose that ifthe "Mr Smith" ofHume's letter is not John Smith of Dublin, then he can only be Adam Smith, and that thelatter musthave written the Abstract. I wish to consider further evidence, some of it circumstantial, relevant to this discussion. This evidence adds probability, I submit, to the conclusion that Hume wrote the Abstract. 1. In the autumn of1737 Hume told Henry Home that he could not give him a "general Notion ofthe Plan" or "Abridgement" ofwhat was to be the Treatise. A careless reading ofthe Abstract might lead one to suppose that this is evidence that Hume did not write this short work. But in fact the Abstract is not an abridgement. It is an effort to make clearer, by carefully tracing "one simple argument... from the beginning to the end," a work thathad been "complained of as obscure and difficult." 3 The available evidence confirms one in the belief that Hume could not abridge the Treatise, but on several occasions he did recast parts ofit in more accessible form. The first such recasting was theAbstract. That this briefworkis not merely an abridgement makes Volume XIX Number 1 217 DAVID FATE NORTON itless likely, I suggest, thatit was written by anyone other than Hume himself.4 2.The Abstract, although said to be "Printed for C. [C]orbet,B at Addison's Head, over-against St. Dunstan's Church, in Fleet-street," wasinfactprintedbyWilUam Strahan, fornone otherthanJohnNoon, the publisher of the Treatise.6 This we know from Strahan's ledgers. These are preservedin the British Library.7Moreover, onApril 19 and 20, 1739, Corbett placed the following advertisement in the London Daily Post and GeneralAdvertiser: Gentlemen, As I have very lately undertaken the Business ofa PubUsher, so will I as faithfully execute it, if at any time you please to employ, Your most Obedient, Humble Servant, Charles Corbett, Who will Inviolably keep secret all Names of Authors, Proprietors, &c. whatever. The fact that Corbett indicates his willingness to undertake clandestine, vanity publishing gives all the explanation one needs of his willingness to become front man for a puffproduced by Hume, and financed, as the Abstract was, by Hume's publisher.8 The fact that it was Noon who arranged for the London printing of the Abstract in no way proves that this work was written by Hume, but it is another bit ofevidence supportive ofthatconclusion,foritindicates thatNoon was in on the effort to publicize the poorly selling volumes ofthe Treatise that he had published.9 3.Robert Connon found a copy of volume three of the Treatise containing extensive manuscript amendments in Hume's hand. As he has also reported, a copy of the Abstract is bound together with this copy ofvolume three, and this copy ofthe Abstract is also amended by Hume. These amendments appear to be those of an author, not... (shrink)

Ecosystem health, as James Nelson argues, must be understood as having both descriptive and normative content; it is in this sense a 'morally thick' concept. The health analogy refers (a) at the similarities between conservation ecology and medicine or plant pathology as normative sciences, and (b) to the ability of ecosystems to 'heal' themselves in the face of disturbances. Nelson, however, goes beyond these two aspects and argues that judgements of illness in ecosystems only support moral obligations to protect them (...) if they are attributed a 'good of their own'. But this latter extension of the analogy flies in the face of ecological science, which has been forced to abandon organicism. If one separates the question of the warranted assertibility of environmentalists' goals from the question of where values in nature are located, the search for an objective realm of value realism can be seen to be unnecessary.

This posthumous and unfinished book by the author of The Revolt of the Masses is in the continental tradition of philosophy as literature. The theme of this historical and etymological essay is the justification of that tradition. Ortega's writing is graceful, and includes aphorisms intended to evoke in the reader the philosophical frame of mind, and a sense of wonder. He finds that philosophy so far has provided no system which is adequately true for us; it is dialectical, revealing the (...) past as a defunct world of errors, which are at the same time involuntary instruments of future truth.. In ancient Greece man first felt an excess of possibilities over needs, both in economics and in explanation. The consequent necessity to choose brought about the phenomenon of rationalism. The means of choosing constitutes method. Science and theology thus emerge in Greece as secondary speculations on primary poetic-mythological explanations. In chapters on Parmenides and Heraclitus, Ortega analyzes the style of each, and illustrates his views on the relation between style and the growth of philosophy. His tool here he calls "etymology," although to those trained in the Anglo-American tradition, his word-analysis is more lyrical than analytic. He concludes that Heraclitus used the oracular or sibylline formula for expressing universal wisdom, and that this in fact is philosophy's most suitable vehicle of expression.—M. B. M. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:RECLAIMING LIBERALISM * DOUGLAS B. RASMUSSEN St. John's University Jamaica, New York Through the shift of emphasis from natural duties or obligations to natural rights, the individual, the ego, had become the center and origin of the moral world, since man-as distinguished from man's end-had become that center or origin. -Leo Strauss T:HE CONCEPTION of individuality that lies at the oundation of natural rights classical liberalism has been a (...) arget of criticism for some time. This is not news. What is news and what is becoming more apparent to those who examine the issue is that the alternatives Strauss presents in the above quotation are not mutually exclusive. Indeed, as I and my colleague, Douglas J. Den Uyl, have recently observed: Making the individual the moral center of the universe does not require that one accept nominalism, mechanism, or hedonism, nor does accepting essentialism, teleology, and eudaimonism... require rejecting individualism. It is possible for the fulfillment of the individual to be interpreted in terms of the requirements for human wellbeing. There can be a view of the ego or self that is neither otherwordly nor Hobbesian, but Aristotelian. Further, the achievement of man's natural end need not be interpreted along Platonic lines. There is no such thing as the flourishing of "man." There is only the flourishing of individual men. The human good neither exists apart from the chokes and actions of individual human beings nor independent of the particular " mix " of goods that the individual human being must determine as appropriate for his circumstances. *This essay is based on a paper presented at a meeting of the American Association for the Philosophic Study of Society, American Philosophical Association (Eastern Division) convention, December 29, 1991 in New York City. This meeting was devoted to David L. Norton's book Democracy and Moral Development (Berkeley: University of California Press, 1991). 109 110 DOUGLAS B. RASMUSSEN Strauss's dichotomy betrays a disturbing tendency, often found among proponents of natural right and natural law, to reify the concept " natural end " and make it some good that competes with the good of individual human beings.1 David L. Norton in his recent work, Democracy and Moral Development, has also noted the nonexclusivity of Strauss's alternatives. Conditioned as we are by modernity's conception of the individual, the question of replacing avarice as the thematic motivation in lives of persons is likely to leave us at a loss. What else could possibly serve? The purpose of this book is to propose the eudaimonistic answer, and that answer is love in the meaning of Eros. Thus understood, love is not exclusively or primarily interpersonal; it is first of all the right relationship of each person with himself or herself. The self to which love is in the first instance directed is the ideal self that is aspired to and by which random change is transformed into the directed development we term growth. When the ideal of the individual is rightly chosen, it realizes objective values that subsisted within the individual as innate potentialities, thereby achieving in the individual the self-identity that is termed "integrity" and that constitutes the foundation of other virtues.2 Norton desires to reconceptualize the individualism historically associated with classical liberalism so as both to retain the gains of classical liberalism and to overcome its moral minimalism. According to Norton, the crucial problem with the conception of individuality historically associated with classical liberalism is that it is "non-developmental," or rather, there is only development within a single stage, namely, for self-preservation. There is nothing more. There is no standard of self-perfection by which to distinguish satisfaction of desire from satisfaction of right desire -no way to distinguish Socrates's satisfaction from that of a fool's. Norton thus seeks to replace classical liberalism's non-developmental conception of individuality with a eudaimonistic conception of the individual. 1 Douglas B. Rasmussen and Douglas J.

The question of where, between theory and experiment, computer simulations (CSs) locate on the methodological map is one of the central questions in the epistemology of simulation (cf. Saam Journal for General Philosophy of Science, 48, 293–309, 2017). The two extremes on the map have them either be a kind of experiment in their own right (e.g. Barberousse et al. Synthese, 169, 557–574, 2009; Morgan 2002, 2003, Journal of Economic Methodology, 12(2), 317–329, 2005; Morrison Philosophical Studies, 143, 33–57, 2009; Morrison (...) 2015; Massimi and Bhimji Studies in History and Philosophy of Science Part B: Studies in History and Philosophy of Modern Physics, 51, 71–81, 2015; Parker Synthese, 169, 483–496, 2009) or just an argument executed with the aid of a computer (e.g. Beisbart European Journal for Philosophy of Science, 2, 395–434, 2012; Beisbart and Norton International Studies in the Philosophy of Science, 26, 403–422, 2012). There exist multiple versions of the first kind of position, whereas the latter is rather unified. I will argue that, while many claims about the ‘experimental’ status of CSs seem unjustified, there is a variant of the first position that seems preferable. In particular I will argue that while CSs respect the logic of (deductively valid) arguments, they neither agree with their pragmatics nor their epistemology. I will then lay out in what sense CSs can fruitfully be seen as experiments, and what features set them apart from traditional experiments nonetheless. I conclude that they should be seen as surrogate experiments, i.e. experiments executed consciously on the wrong kind of system, but with an exploitable connection to the system of interest. Finally, I contrast my view with that of Beisbart (European Journal for Philosophy of Science, 8, 171–204, 2018), according to which CSs are surrogates for experiments, arguing that this introduces an arbitrary split between CSs and other kinds of simulations.

Subramanian has produced a new biography of Haldane taking into account archival material that has only become public during the last decade. He has been able to provide a more complete picture of Haldane’s personal life than earlier biographers, such as his difficult schooldays at Eton and the deterioration of his first marriage. He has also highlighted the extent to which Haldane was kept under constant secret surveillance by British intelligence services because of his politics. However, the book is less (...) successful in its account of Haldane’s scientific work including what he contributed to modern evolutionary theory, the Fisher–Haldane relationship, Haldane’s role in the Lysenko controversy, and what he achieved after emigration to India in 1957.

There has recently been a good deal of controversy about Landauer's Principle, which is often stated as follows: The erasure of one bit of information in a computational device is necessarily accompanied by a generation of kTln2 heat. This is often generalised to the claim that any logically irreversible operation cannot be implemented in a thermodynamically reversible way. John Norton (2005) and Owen Maroney (2005) both argue that Landauer's Principle has not been shown to hold in general, and Maroney (...) offers a method that he claims instantiates the operation Reset in a thermodynamically reversible way. In this paper we defend the qualitative form of Landauer's Principle, and clarify its quantitative consequences (assuming the second law of thermodynamics). We analyse in detail what it means for a physical system to implement a logical transformation L, and we make this precise by defining the notion of an L-machine. Then we show that logical irreversibility of L implies thermodynamic irreversibility of every corresponding L-machine. We do this in two ways. First, by assuming the phenomenological validity of the Kelvin statement of the second law, and second, by using information-theoretic reasoning. We illustrate our results with the example of the logical transformation 'Reset', and thereby recover the quantitative form of Landauer's Principle. (shrink)

Woodger's substitution of the "allegedly more precise term 'an environmentally insensitive set of lives'" for the term 'an inborn character' is discussed by haldane. He proposes that "woodger's definitions do not appear to have reached precision." (staff).

The thesis that there can be vague objects is the thesis that there can be identity statements which are indeterminate in truth-value (i.e., neither true nor false) as a result of vagueness (as opposed, e.g., to reference-failure), "the singular terms of which do not have their references fixed by vague descriptive means". (if this is "not" what is meant by the thesis that there can be vague objects, it is not clear what "is" meant by it.) the possibility of vague (...) objects should not be taken, in itself, to imply the more radical thesis that the identity relation can be one of "degree". one can hold that the concept of degrees of identity is absurd (how can one thing be more or less identical to another?) "and" that indeterminacy in identity is possible; hence, any incoherence in the idea of degrees of identity does not thereby undermine the idea of indeterminate identity. (shrink)

The role of microaggressions has gained increasing philosophical attention in recent years. However, microaggressions only tell part of the story. An often-overlooked component of inequality is the uneven and unjust distribution of microaffirmations. In this paper, I give a new definition of microaffirmations as signals that a recipient belongs to some valued or high-status class. Microaffirmations can—but need not—lead individuals to gain a sense of confidence, belonging, and merit. I then explain the harms of microaffirmations, arguing that when microaffirmations are (...) distributed inequitably, they can have larger ramifications for injustice, harming some vulnerable groups more than others. In addition, microaffirmations can lead individual actors to make choices based on who gives them microaffirmations and where they receive them, and thus can have outsized influence over the direction of an individual’s life because individuals tend to migrate to where they feel valued, appreciated, and included. I then turn to solutions to the problems I raise. I argue we should attend to and attempt to rectify inequalities in microaffirmations because doing so can help ensure not just the absence of negative attention, but also that the presence of positive attention is flowing in a just and equitable way.

Il y a un conflit entre les normes surnaturelles qui ne tiennent pas compte des possibilités humaines et les normes naturelles qui conduisent à des règles d’action fondées sur la connaissance positive du milieu où nous vivons ; mais il est impossible que les secondes affranchissent l’homme des premières.

It has been argued that neural networks and other forms of analog computation may transcend the limits of Turing-machine computation; proofs have been offered on both sides, subject to differing assumptions. In this article I argue that the important comparisons between the two models of computation are not so much mathematical as epistemological. The Turing-machine model makes assumptions about information representation and processing that are badly matched to the realities of natural computation (information representation and processing in or inspired by (...) natural systems). This points to the need for new models of computation addressing issues orthogonal to those that have occupied the traditional theory of computation. (shrink)
