Using fMRI, we investigated how right temporal lobe gliomas affecting the posterior superior temporal sulcus alter neural processing observed during speech perception and production tasks. Behavioural language testing showed that three pre-operative neurosurgical patients with grade 2, grade 3 or grade 4 tumours had the same pattern of mild language impairment in the domains of object naming and written word comprehension. When matching heard words for semantic relatedness (a speech perception task), these patients showed under-activation in the tumour infiltrated right (...) superior temporal lobe compared to 61 neurotypical participants and 16 patients with tumours that preserved the right postero-superior temporal lobe, with enhanced activation within the (tumour-free) contralateral left superior temporal lobe. In contrast, when correctly naming objects (a speech production task), the patients with right postero-superior temporal lobe tumours showed higher activation than both control groups in the same right postero-superior temporal lobe region that was under-activated during auditory semantic matching. The task dependent pattern of under-activation during the auditory speech task and over-activation during object naming was also observed in eight stroke patients with right hemisphere infarcts that affected the right postero-superior temporal lobe compared to eight stroke patients with right hemisphere infarcts that spared it. These task-specific and site-specific cross-pathology effects highlight the importance of the right temporal lobe for language processing and motivate further study of how right temporal lobe tumours affect language performance and neural reorganisation. These findings may have important implications for surgical management of these patients, as knowledge of the regions showing functional reorganisation may help to avoid their inadvertent damage during neurosurgery.

We present a one per cent measurement of the cosmic distance scale from the detections of the baryon acoustic oscillations in the clustering of galaxies from the Baryon Oscillation Spectroscopic Survey, which is part of the Sloan Digital Sky Survey III. Our results come from the Data Release 11 sample, containing nearly one million galaxies and covering approximately 8500 square degrees and the redshift range 0.2 < z < 0.7. We also compare these results with those from the publicly released (...) DR9 and DR10 samples. Assuming a concordance Λ cold dark matter cosmological model, the DR11 sample covers a volume of 13 Gpc3 and is the largest region of the Universe ever surveyed at this density. We measure the correlation function and power spectrum, including density-field reconstruction of the BAO feature. The acoustic features are detected at a significance of over 7σ in both the correlation function and power spectrum. Fitting for the position of the acoustic features measures the distance relative to the sound horizon at the drag epoch, rd, which has a value of rd,fid = 149.28 Mpc in our fiducial cosmology. We find DV = at z = 0.32 and DV = at z = 0.57. At 1.0 per cent, this latter measure is the most precise distance constraint ever obtained from a galaxy survey. Separating the clustering along and transverse to the line of sight yields measurements at z = 0.57 of DA = and H =. Our measurements of the distance scale are in good agreement with previous BAO measurements and with the predictions from cosmic microwave background data for a spatially flat CDM model with a cosmological constant. © 2014 The Author Published by Oxford University Press on behalf of the Royal Astronomical Society.

In lieu of an abstract, here is a brief excerpt of the content:Joseph Priestley's Criticisms of David Hume's Philosophy RICHARD H. POPKIN ONE OF HUME'S MOST FAMOUS CRITICS, the great scientist Joseph Priestley (1733-1804), is scarcely mentioned or studied in the Hume literature.' Perhaps because of the course philosophy followed after Hume, the Scottish Common Sense critics and the German ones connected with Kant are given almost all of the attention. In this paper 1 shall try to correct this (...) oversight, and examine the background of Priestley's critique of Hume, both in terms of Priestley's scientific and religious views and in terms of Hume's influence at the time. I shall then evaluate the merits of Priestley's critique and attempt to determine whether it deserves further study or should be returned to the obscurity it has been in for almost two centuries. 2 Joseph Priestley was a nonconforming minister whose progressively radical views caused him to lose various posts. Eventually he became a millenarian, convinced that crucial signs of the end of the world were at hand: the events of the French Revolution; the purported discovery of the Lost Tribes in Afghanistan by Sir William Jones; plans or hopes for the Jews to return to Palestine and join forces with the Christians. After years of religious wanderings Priestley ended up a millenarian Unitarian, much in the tradition of Sir Isaac Newton, whose religious writing he used extensively, and of Newton's successor, William Whiston? Priestley taught science in various schools and was immensely influenced by David Hartley's Observations on Man. He found in Hartley's theory of association of ideas a naturalistic way of explaining human mental life. And in Hartley's millenarian views he located the sort of theology he was seeking. Priestly later reedited Hartley, including introductory essays about some of the more difficult aspects of his mechanistic psychology.' (Coleridge, who was deeply impressed by ' T. E. Jessop, A Bibliography of David Hume and of the Scottish Philosophy from l-)'ancis Hutcheson to Lord Balfour (New York, 1966), lists the titles of Priestley's works relevant to Hume. However, there appear to be no discussions of Priestley on Hume listed in this work or in Roland Hill, A Bibliography of David Hume from 1930 (York, 1971). E. C. Mossner, The Life of David Hume (Edinburgh, 1954), mentions Priestley's criticisms of Hume, but only as these were made in connection with criticisms of Beattie. Joseph Priestley, Memoirs of Dr. Joseph Priestley to the Year 1795, written by Himself, with a Continuation to the time of his decease by his son, Joseph Priestley, ed. T. Cooper (London, 1806). It is also of some interest that Priestley attacked Reid, Beattie, and Oswald a few years before challenging Hume. He seemed to think that he had disposed of the Scottish Philosophy for all time. Thus Priestley was certainly no part of the mainstream of Hume's opponents in Britain. See Memoirs, pp. 78-79n, and n. 16 below. ' On Priestley's career, see his Memoirs. Modern biographies deal principally with his scientific achievements and ignore or play down his theological concerns. For an extended discussion of Priestley's millenarian views, see Clarke Garrett, Respectable Folly (Baltimore, 1975), pp. 126-143. " Priestley, Hartley's Theory of the Human Mind, on the Principle of the Association of Ideas... (London, 1775). [437] 438 HISTORY OF PHILOSOPHY Hartley, probably read Priestley's edition of his works.) For the most part, Priestley wrote long and controversial works on theology. His scientific achievements stem from his friendship with Benjamin Franklin and Richard Price, who encouraged him to write a history of discoveries in electricity. Franklin provided the resources for making the equipment. On the basis of the new material in his work, Priestley was nominated to the Royal Society by Franklin and Price. s Priestley's most famous scientific works came thereafter--his discovery of oxygen and his work on how the human body used oxygen. Later still, he became entangled in a controversy with Lavoisier over the phlogiston theory, Priestley upholding it, the French chemist opposing it. 6 Priestley was also active in politics, supporting radical causes. He supported John Wilkes, of whom Hume thoroughly disapproved, and was an early... (shrink)

Philosophers in the tradition of Berkeley say that the first step in gaining knowledge from perception is to report or describe one's perceptual data, or that which one sees ‘immediately'. Further, perceptual data are existing things of some sort, and always are exactly as they appear to be since, as H. H. Price says, “in the sphere of the given … what seems, is”. However, these two claims about perceptual data are sometimes incompatible, as the following case shows. Suppose (...) a man looking at a speckled hen reports that it has many speckles but is not able to report the exact number of speckles it has. If above is correct, the man's perceptual datum, as opposed to the physical hen itself which he sees—according to Berkeleians—in a merely indirect sense, would have to be indeterminate in character. Yet we assume that everything which exists ) is and has to be completely determinate. A person's knowledge is indeterminate if he knows that the planet Mars has either two or three satellites and doesn't know which. But Mars itself at any moment has to have some definite number of satellites. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:?;5. HUME AND SPINOZA It is strange that there has been so little interest in comparing two great philosophers, Hume and -Spinoza, who were both so important and influential in bringing about the decline of traditional religion. Jessop's bibliography indicates no interest in Hume and Spinoza up to the 1930 's. The Hume conferences of 1976, as far as I have been able to 2 determine, avoided the topic. (...) In one of the better new Hume volumes, Livingston and King, Hume, A Re-evaluation, 3 Spinoza is cited twice, and once incorrectly at that. On the other hand, in the massive new Spinoza volume edited by Siegfried Hessing, Speculum Spinozanun 1677-1977, Hume is mentioned four times, but only one of these has any real relevance to Hume's views vis-a-vis Spinoza's. Some discussion of Hume's comments, usually brief, occurs in the commentators. B. M. Laing, in David Hume, (London 1932), has just three short references to Spinoza. John Laird, in Hume's Philosophy of Human Nature, (London 1932) has a couple of cursory references to Spinoza, plus a bit more extended statement of Pierre Bay le" s critique of him. In H. H. Price, Hume's Theory of the External World, (Oxford 1940), there is one paragraph on Hume and Spinoza. In Norman Kemp Smith, The Philosophy of David Hume (London 1941), there are three references to Spinoza. Rachel Kydd, Reason and Conduct in Hume's Treatise (Oxford 194 6), has the greatest number of references to Spinoza. She was concerned to compare him with Hume on other matters than are dealt with in this paper, namely Spinoza's theory of reason and 9 the passions. In contrast, André Leroy, David Hume, (Paris 1953), has just one paragraph on Spinoza dealing with the immateriality of the soul; and Ernest C. Mossner, in his monumental Life of David Hume, (Austin 1954), has only one reference to Spinoza - James Beattie's denunciation of Hume, Hobbes, Malebranche, Leibniz and Spinoza. Lastly, in a fairly recent commentary by James Noxon, Spinoza is mentioned 66. three times, but not for anything in Hume's text. Noxon does point out (p. 75) that Spinoza is not mentioned in ] 2 Hume's correspondence. John H. Randall has offered an explanation for this neglect of Spinoza by Hume scholars, namely that "Hume stands for all time as the antithesis of Spinoza in his thought". In the England of Hume's day, Spinoza was little known, but still better known at the time than he was in France or England. Spinoza's Tractatus Theologico-Politicus 14 had been twice translated into English anonymously. He had been attacked by Bishop Stillingfleet, by John Evelyn, by Berkeley and several others. But Spinoza was not a major figure, except to the English Deists, and to Hume's early patron, the Chevalier Andrew Michael Ramsay. Most of the information known about Spinoza came from Pierre Bayle' s Historical and Critical Dictionary, where the article "Spinoza" is the longest in the Dictionary, about three hundred pages in length. My suspicion, or hypothesis, is that Hume first became interested in Spinoza through Ramsay, and then learned what he knew about Spinoza from Bayle' s article. When the young David Hume went to France to write his A Treatise of Human Nature in 1734, he went first to see the Chevalier Ramsay, who entertained Hume for about two weeks. Ramsay was a leading Scottish Catholic, was the teacher of Bonnie Prince Charlie, a leading Scottish revolutionary, 18 as well as the Grand Master of the Free Masons. With Ramsay's eclectic views it is not odd that he had a serious interest in Spinoza's theory, and that he was composing answers to it. Ramsay advised Hume about his own book, and Hume felt he had to show Ramsay the Treatise before he 19 brought it back to England. In the Treatise there is a not too well studied section on Spinoza, Of the immateriality of the soul 20 (T240-45). In introducing Spinoza into the discussion of 67. the immateriality of the soul, Hume follows what was common practice in his day, namely to insult Spinoza and his theory... (shrink)

This book offers a definitive and wide-ranging overview of developments in behavioral finance over the past ten years. In 1993, the first volume provided the standard reference to this new approach in finance--an approach that, as editor Richard Thaler put it, "entertains the possibility that some of the agents in the economy behave less than fully rationally some of the time." Much has changed since then. Not least, the bursting of the Internet bubble and the subsequent market decline further demonstrated (...) that financial markets often fail to behave as they would if trading were truly dominated by the fully rational investors who populate financial theories. Behavioral finance has made an indelible mark on areas from asset pricing to individual investor behavior to corporate finance, and continues to see exciting empirical and theoretical advances. Advances in Behavioral Finance, Volume II constitutes the essential new resource in the field. It presents twenty recent papers by leading specialists that illustrate the abiding power of behavioral finance--of how specific departures from fully rational decision making by individual market agents can provide explanations of otherwise puzzling market phenomena. As with the first volume, it reaches beyond the world of finance to suggest, powerfully, the importance of pursuing behavioral approaches to other areas of economic life. The contributors are Brad M.

My primary aim in this paper is to show that the structure of experience must include a subject (or self). I argue that the subjectless (No-Self) views of our experience must be rejected, primarily because without the consciousness-unifying function of a subject they are unable to account for the unities of consciousness present in our experience. In addition, I contend that such views fail in another respect. They emphasize the streaming of experience, the ever-changing flow of conscious events, but have (...) difficulty identifying what must stand unmoving to provide the contrast needed for the experience of motion.

Henry Habberley Price, who published as H. H. Price, was born in 1899. From 1935 to 1959 he was Wykeham Professor of Logic at Oxford University. Price was a major figure in his lifetime well-known especially for the “clarity and elegance of style”, which, according to Martha Kneale (1996: xix), make his works readable in spite of changing fashions in philosophy. Many people’s acquaintance nowadays with Price’s philosophical work derives from his being a target in Austin’s (...) (1962) famous attack on the sense-datum theory. This restricted acquaintance with his output is one reason that Price has been ignored in recent philosophy. -/- Mainstream philosophy neglected him after the Second World War, perhaps partly because, when articulating his ideas, he mainly engaged with philosophers of the past, such as Locke and Hume. His thought was, however, valued by fellow philosophers such as Broad, Moore, Ayer, and generations of his students at Oxford, including Sellars, Armstrong, and Anscombe. -/- Although Price is seen mainly as a philosopher of perception, only two of his six books are about perception and he had a major influence, also publishing many articles, on a variety of topics, including some we cannot focus on here, e.g., our evidence of other minds (1938; 1930b: 195) and psychical research (1940c; 1953b; 1972; 1995; an interest he claims to share with Neo-Platonists [1968a: 447]). We can only provide a sketch of his rich contributions. After briefly sketching his life (§1), we discuss his philosophy’s general features (§2), contributions to the studies of perception (§3), properties (§5.1), recognition (§5), belief (§6), religious belief (§6.8), his revival and serious study of Hume (§4), and some remarkable anticipations (§7).

In the form of inference known as inference to the best explanation there are various ways to characterise what is meant by the best explanation. This paper considers a number of such characterisations including several based on confirmation measures and several based on coherence measures. The goal is to find a measure which adequately captures what is meant by 'best' and which also yields the truth with a high degree of probability. Computer simulations are used to show that the overlap (...) coherence measure achieves this goal, enabling the true explanation to be identified almost as often as an approach which simply selects the most probable explanation. Further advantages to this approach are also considered in the case where there is uncertainty in the prior probability distribution. (shrink)

How good is an explanation and when is one explanation better than another? In this paper, I address these questions by exploring probabilistic measures of explanatory power in order to defend a particular Bayesian account of explanatory goodness. Critical to this discussion is a distinction between weak and strong measures of explanatory power due to Good (Br J Philos Sci 19:123–143, 1968). In particular, I argue that if one is interested in the overall goodness of an explanation, an appropriate balance (...) needs to be struck between the weak explanatory power and the complexity of a hypothesis. In light of this, I provide a new defence of a strong measure proposed by Good by providing new derivations of it, comparing it with other measures and exploring its connection with information, confirmation and explanatory virtues. Furthermore, Good really presented a family of strong measures, whereas I draw on a complexity criterion that favours a specific measure and hence provides a more precise way to quantify explanatory goodness.

This paper presents a new argument for the likelihood ratio measure of confirmation by showing that one of the adequacy criteria used in another argument can be replaced by a more plausible and better supported criterion which is a special case of the weak likelihood principle. This new argument is also used to show that the likelihood ratio measure is to be preferred to a measure that has recently received support in the literature.

This chapter develops and defends a formal epistemology of conjunctive explanation by determining the conditions under which multiple distinct explanations are better than one. The general approach is to identify an appropriate measure of explanatory goodness that can then be applied to conjunctive explanations. If a conjunctive explanation is to be preferred it needs to have greater explanatory virtue (e.g., power or scope) with respect to the evidence, but this explanatory gain is insufficient on its own. Given a conjunctive explanation’s (...) greater complexity, it also has a cost associated with it and so a balance needs to be struck between the gain and the cost. This is achieved by employing a Bayesian measure proposed by I. J. Good. This chapter explores some properties of this measure and its application to the epistemology of conjunctive explanation. In so doing, it addresses the general question of whether it is desirable to have more informative, less probable hypotheses when seeking good explanations. (shrink)

At least since Descartes, philosophers have been interested in the special knowledge or authority that we exhibit when we speak about our own thoughts, attitudes, and feelings. This book contends that even the best work in contemporary philosophy of mind fails to account for this sort of knowledge or authority because it does not pay the right sort of attention to the notion of expression. What's at stake is not only how to understand self-knowledge and first-person authority, but also what (...) it is that distinguishes conscious from unconscious psychological states, what the mental life of a nonlinguistic animal has in common with our sort of mental life, and how to think about Wittgenstein's legacy to the philosophy of mind.

This paper considers an application of work on probabilistic measures of coherence to inference to the best explanation. Rather than considering information reported from different sources, as is usually the case when discussing coherence measures, the approach adopted here is to use a coherence measure to rank competing explanations in terms of their coherence with a piece of evidence. By adopting such an approach IBE can be made more precise and so a major objection to this mode of reasoning can (...) be addressed. Advantages of the coherence - based approach are pointed out by comparing it with several other ways to characterize ‘ best explanation ’ and showing that it takes into account their insights while overcoming some of their problems. The consequences of adopting this approach for IBE are discussed in the context of recent discussions about the relationship between IBE and Bayesianism. (shrink)

This paper provides a new approach to inference to the best explanation based on a new coherence measure for comparing how well hypotheses explain the evidence. It addresses a number of criticisms of the use of probabilistic measures in this context by Clark Glymour, including limitations of earlier work on IBE. Computer experiments are used to show that the new approach finds the truth with a high degree of accuracy in hypothesis selection tasks and that in some cases its accuracy (...) is greater than hypothesis selection based on maximizing posterior probability. Hence, by overcoming some of the problems with the previous approach, this work provides a more adequate defence of IBE and suggests that IBE not only tracks truth but also has practical advantages over the previous approach. Applications of the new approach to parameter estimation and model selection are also explored. (shrink)

I propose a qualitative Bayesian account of explanatory goodness that is analogous to the Bayesian account of incremental confirmation. This is achieved by means of a complexity criterion according to which an explanation h is good if the reduction in the complexity of the explanandum e brought about by h (the explanatory gain) is greater than the additional complexity introduced by h in the context of e (the explanatory cost). To illustrate the account, I apply it in the context of (...) ad hoc hypotheses. (shrink)

Two of the probabilistic measures of coherence discussed in this paper take probabilistic dependence into account and so depend on prior probabilities in a fundamental way. An example is given which suggests that this prior-dependence can lead to potential problems. Another coherence measure is shown to be independent of prior probabilities in a clearly defined sense and consequently is able to avoid such problems. The issue of prior-dependence is linked to the fact that the first two measures can be understood (...) as measures of coherence as striking agreement, while the third measure represents coherence as agreement. Thus, prior (in)dependence can be used to distinguish different conceptions of coherence. (shrink)

We present a conceptual framework on the experience of time and provide a coherent basis on which to base further inquiries into qualitative approaches concerning time experience. We propose two Time-Layers and two Time-Formats forming four Time-Domains. Micro-Flow and Micro-Structure represent the implicit phenomenal basis, from which the explicit experiences of Macro-Flow and Macro-Structure emerge. Complementary to this theoretical proposal, we present empirical results from qualitative content analysis obtained from 25 healthy participants. The data essentially corroborate the theoretical proposal. With (...) respect to Flow, the phenomenally accessible time experience appeared as a continuous passage reaching from the past through the present into the future. With respect to Structure, the individual present was embedded in the individual biography, emerging from past experiences and comprising individual plans and goals. New or changing plans and goals were being integrated into the existing present, thus forming a new present. The future appeared as changeable within the present, by means from the past, and therefore as a space of potential opportunities. Exemplarily, we discuss these results in relation to previous empirical findings on deviant experiences of time in Autism Spectrum Disorder that is presumably characterized by a breakdown of Flow and concomitant compensatory repetition resulting in an overly structured time. Finally, we speculate about possible implications of these findings both for psychopathological and neuroscientific research. (shrink)

Naive mereology studies ordinary, common-sense beliefs about part and whole. Some of the speculations in this article on naive mereology do not bear directly on Peter van Inwagen's "Material Beings". The other topics, (1) and (2), both do. (1) Here is an example of Peter Unger's "Problem of the Many". How can a table be a collection of atoms when many collections of atoms have equally strong claims to be that table? Van Inwagen invokes fuzzy sets to solve this problem. (...) I claim that an alternative treatment of vagueness, supervaluations over many-value valuations, provides a better solution. (2) The Special Composition Question asks how parts compose a whole. One who rejects van Inwagen's answer in terms of constituting a life need not provide some alternative answer. Even if all answers to the Special Question fail, there are a multitude of less general composition questions that are not so difficult. (shrink)

A primary purpose of argument is to increase the degree of reasonable confidence that one has in the truth of the conclusion. A question begging argument fails this purpose because it violates what W. E. Johnson called an epistemic condition of inference. Although an argument of the sort characterized by Robert Hoffman in his response (Analysis 32.2, Dec 71) to Richard Robinson (Analysis 31.4, March 71) begs the question in all circumstances, we usually understand the charge that an argument is (...) question begging with reference to the beliefs of the person, or the sort of person, to whom the argument is directed.

This is the first of two papers that use off-training set (OTS) error to investigate the assumption-free relationship between learning algorithms. This first paper discusses the senses in which there are no a priori distinctions between learning algorithms. (The second paper discusses the senses in which there are such distinctions.) In this first paper it is shown, loosely speaking, that for any two algorithms A and B, there are “as many” targets (or priors over targets) for which A has lower (...) expected OTS error than B as vice versa, for loss functions like zero-one loss. In particular, this is true if A is cross-validation and B is “anti-cross-validation” (choose the learning algorithm with largest cross-validation error). This paper ends with a discussion of the implications of these results for computational learning theory. It is shown that one cannot say: if empirical misclassification rate is low, the Vapnik-Chervonenkis dimension of your generalizer is small, and the training set is large, then with high probability your OTS error is small. Other implications for “membership queries” algorithms and “punting” algorithms are also discussed. (shrink)

Richard Dawkins has a dilemma when it comes to design arguments. On the one hand, he maintains that it was Darwin who killed off design and so implies that his rejection of design depends upon the findings of modern science. On the other hand, he follows Hume when he claims that appealing to a designer does not explain anything and so implies that rejection of design need not be based on the findings of modern science. These contrasting approaches lead to (...) the following dilemma: if he claims that Darwinism is necessary for rejecting design, he has no satisfactory response to design arguments based on the order in the laws of physics or the fine-tuning of the physical constants; alternatively, if Humean arguments are doing most of the work, this would undermine one of his main contentions, that atheism is justified by science and especially by evolution. In any case, his Humean arguments do not provide a more secure basis for his atheism because they are seriously flawed. A particular problem is that his argument for the improbability of theism rests on a highly questionable application of probability theory since, even if it were sound, it would only establish that the prior probability of God’s existence is low, a conclusion which is compatible with the posterior probability of God’s existence being high.

The important recent book by Schurz ( 2019 ) appreciates that the no-free-lunch theorems (NFL) have major implications for the problem of (meta) induction. Here I review the NFL theorems, emphasizing that they do not only concern the case where there is a uniform prior—they prove that there are “as many priors” (loosely speaking) for which any induction algorithm _A_ out-generalizes some induction algorithm _B_ as vice-versa. Importantly though, in addition to the NFL theorems, there are many _free lunch_ theorems. (...) In particular, the NFL theorems can only be used to compare the expected performance of an induction algorithm _A_, considered in isolation, with the expected performance of an induction algorithm _B_, considered in isolation. There is a rich set of free lunches which instead concern the statistical _correlations_ among the generalization errors of induction algorithms. As I describe, the meta-induction algorithms that Schurz advocates as a “solution to Hume’s problem” are simply examples of such a free lunch based on correlations among the generalization errors of induction algorithms. I end by pointing out that the prior that Schurz advocates, which is uniform over bit frequencies rather than bit patterns, is contradicted by thousands of experiments in statistical physics and by the great success of the maximum entropy procedure in inductive inference.

The epistemic arrow of time is the fact that our knowledge of the past seems to be both of a different kind and more detailed than our knowledge of the future. Just like with the other arrows of time, it has often been speculated that the epistemic arrow arises due to the second law of thermodynamics. In this paper, we investigate the epistemic arrow of time using a fully formal framework. We begin by defining a memory system as any physical (...) system whose present state can provide information about the state of the external world at some time other than the present. We then identify two types of memory systems in our universe, along with an important special case of the first type, which we distinguish as a third type of memory system. We show that two of these types of memory systems are time-symmetric, able to provide knowledge about both the past and the future. However, the third type of memory systems exploits the second law of thermodynamics, at least in all of its instances in our universe that we are aware of. The result is that in our universe, this type of memory system only ever provides information about the past. We also argue that human memory is of this third type, completing the argument. We end by scrutinizing the basis of the second law itself. This uncovers a previously unappreciated formal problem for common arguments that try to derive the second law from the “Past Hypothesis”, i.e., from the claim that the very early universe was in a state of extremely low entropy. Our analysis is indebted to prior work by one of us but expands and improves upon this work in several respects. (shrink)
