Do dissociations imply independent systems? In the memory field, the view that there are independent implicit and explicit memory systems has been predominantly supported by dissociation evidence. Here, we argue that many of these dissociations do not necessarily imply distinct memory systems. We review recent work with a single-system computational model that extends signal-detection theory (SDT) to implicit memory. SDT has had a major influence on research in a variety of domains. The current work shows that it can be broadened (...) even further in its range of application. Indeed, the single-system model that we present does surprisingly well in accounting for some key dissociations that have been taken as evidence for independent implicit and explicit memory systems.

We present a new modeling framework for recognition memory and repetition priming based on signal detection theory. We use this framework to specify and test the predictions of 4 models: (a) a single-system (SS) model, in which one continuous memory signal drives recognition and priming; (b) a multiple-systems-1 (MS1) model, in which completely independent memory signals (such as explicit and implicit memory) drive recognition and priming; (c) a multiple-systems-2 (MS2) model, in which there are also 2 memory signals, but some (...) degree of dependence is allowed between these 2 signals (and this model subsumes the SS and MS1 models as special cases); and (d) a dual-process signal detection (DPSD1) model, 1 possible extension of a dual-process theory of recognition (Yonelinas, 1994) to priming, in which a signal detection model is augmented by an independent recollection process. The predictions of the models are tested in a continuous-identification-with-recognition paradigm in both normal adults (Experiments 1–3) and amnesic individuals (using data from Conroy, Hopkins, & Squire,2005). The SS model predicted numerous results in advance. These were not predicted by the MS1 model, though could be accommodated by the more flexible MS2 model. Importantly, measures of overall model fit favored the SS model over the others. These results illustrate a new, formal approach to testing theories of explicit and implicit memory. (shrink)

It is widely assumed that selection history accounts of function can support a fully reductive naturalization of functional properties. I argue that this assumption is false. A problem with the alternative causal role account of function in this context is that it invokes the teleological notion of a goal in analysing real function. The selection history account, if it is to have reductive status, must not do the same. But attention to certain cases of selection history in biology, specifically those (...) involving meiotic drive, shows that selection historical explanations are available in the case of items without any plausible function. Making contributions to goals, here fitness, must be introduced as an additional constraint in the analysis, either explicitly, or implicitly by appeal to individual functions or the selection-of/selection-for distinction.

Two ideas govern the organisation of this collection. It is suggested that medieval philosophy is best studied as an interactive debate between thinkers of different times, and also the importance of the Ancient Greek philosophers in this field.

This paper argues that Donald Davidson’s infamous denial in “A Nice Derangement of Epitaphs” that there is any such thing as a language, though it may not be fully supported by the arguments given for it in that paper, is nonetheless entailed by his semantic views generally, according to which the literal, linguistic meaning of a speaker’s words on an occasion is determined by how the speaker intended to be understood. In favor of this view, and thus against conventional languages, (...) the paper then argues that this understanding of linguistic meaning promises, in a way the conventional view of meaning does not, to make sense of linguistic normativity.

Donald Davidson infamously claims that belief is in its nature veridical, and that skepticism is for this reason fundamentally incoherent. To those who take the issue of external world skepticism seriously, Davidson's arguments may seem to involve a conjuring trick. In particular, his invocation of an ‘omniscient interpreter’, whose intelligibility supposedly ensures that our beliefs must be largely true, has the air of incense and lantern-rubbing about it. Davidson's claim has received considerable critical response in the literature, almost all of (...) it negative. In my view, some commentators have indeed lit on a critical and controversial lemma in Davidson's argument, but this basic result has been obscured by being presented amidst an array of other criticisms that simply make no sense from a Davidsonian point of view. The aim of this paper is to clear away some of the confusion that stands in the way of a more productive evaluation of Davidson's important claim. (shrink)

I examine the arguments Donald Davidson has offered through the years concerning the ontological bona fides of facts. In “Truth and Meaning”, Davidson uses the so-called “slingshot” argument to the effect that if true sentences refer, then they are all coreferential. Through a detailed examination of the assumptions underlying this argument, I show that, while it is effective as part of a reductio of bottom-up, reference based semantics, it has no tendency to establish the truth of its negative conclusion concerning (...) the existence of facts. Davidson also argues against facts by claiming they are of no help in the explication of truth. I claim that his repeated invocation of the slingshot in this context, as well as of arguments from other authors employing assumptions similar to the slingshot's, is inappropriate, especially in light of his own commitment to a top-down semantics — a committment inspired, ironically, by the reductio offered in “Truth and Meaning”. Davidson's other argument against truth as correspondence, namely that our grasp of facts is no better than our grasp of truths, is sound. But this argument does not show that there are no facts; it shows only that no theory of truth in terms of corre- pondence to facts can genuinely illuminate its explanandum. (shrink)

Kant distinguishes “natural ends” as exhibiting a part-whole reciprocal causal structure in virtue of which we can only conceive them as having been caused through a conception, as if by intelligent design. Here, I put pressure on Kant’s position by arguing that his view of what individuates and makes cognizable material bodies of any kind is inadequate and needs supplementation. Drawing on Spinoza, I further urge that the needed supplement is precisely the whole-part reciprocal causal structure that Kant takes to (...) be distinctive of natural ends alone. (shrink)

Donald Davidson argues that his interpretivist approach to meaning shows that accounting for the intentionality and objectivity of thought does not require an appeal, as John McDowell has urged it does, to a specifically rational relation between mind and world. Moreover, Davidson claims that the idea of such a relation is unintelligible. This paper takes issue with these claims. It shows, first, that interpretivism, contra Davidson's express view, does not depend essentially upon an appeal to a causal relation between events (...) in the world and speakers' beliefs. Second, it shows that interpretivism essentially, if implicitly, depends upon interpreters' appealing to facts taken in in perception, and that such facts are suited to provide a rational connection between mind and world. The paper then argues that none of Davidson's legitimate epistemological arguments tell against the idea that experience, in the form of the propositional contents of perception, can play a role in doxastic economy. Finally, it argues that granting experience such a role is consistent with Davidson's coherentist slogan that nothing can count as a reason for holding a belief except another belief. (shrink)

This paper is a result of remarks delivered at the 2014 conference of the Florida Philosophical Association during a book symposium on Elijah Chudnoff's Intuition.

This book presents selections from the political and social thought of the ancient West from the early sixth century BCE up to the early years of the Roman Empire and includes not only the classic philosophers, Plato, Aristotle, and Cicero, but a number of dramatists and historians as well. The range of topics these writings treat run from class conflict, through the perils of democracy and the horrors of tyranny, to the place of women in politics, while the styles range (...) from the deeply dramatic of Sophocles' Antigone and the bawdy satire of Aristophanes' Assemblywomen to Plato's Socratic dialogue Republic and Aristotle's scientific treatise Politics. The translations have been chosen, and sometimes modified, for clarity and readability, and are accompanied by introductions which set forth the historical context and trace the general lines of thought the readings develop. Frequent notes explain references to ancient lore unfamiliar to many readers. Questions for discussion accompany each reading. (shrink)

In this important collection, the editors argue that medieval philosophy is best studied as an interactive discussion between thinkers working on very much the same problems despite being often widely separated in time or place. Each section opens with at least one selection from a classical philosopher, and there are many points at which the readings chosen refer to other works that the reader will also find in this collection. There is a considerable amount of material from central figures such (...) as Augustine, Abelard, Duns Scotus, and William of Ockham, as well as extensive texts from thinkers in the medieval Islamic world. Each selection is prefaced by a brief introduction by the editors, providing a philosophical and religious background to help make the material more accessible to the reader. This edition, updated throughout, contains a substantial new chapter on medieval psychology and philosophy of mind, with texts from authors not previously represented such as John Buridan and Peter John Olivi.

This is a collection of essays touching on four distinct areas of interest to philosophers, lawyers, and political scientists: the philosophical justification for the adversary system; the problems of truth-finding in an adversarial setting; the issue of justice in relation to social policy-making; the right to privacy.

Argues that the historical concept of agency ultimately fails since such weighing and choosing always require grounds that reach beyond private consciousness. Agency is bound inherently with morality; the modernist understanding of agency removes it from morality. It is suggested that agency is only possible on inherently moral, rather than metaphysical, grounds. An alternative conceptualization of agency as living truthfully is proposed that does not posit the existence of Cartesian ego and does not surrender to moral relativism. This concept of (...) agency is exemplified and distinguished from volition, which is much closer to the more traditional view of agency as the capacity to choose from among alternatives. A grounding for agency in ethics is offered, suggesting that neither traditional notions, which are grounded in traditional metaphysics, nor postmodern notions, which accept ethical relativity, can render satisfactory accounts of human agency. 2012 APA, all rights reserved).

From the neurophysiological perspective, thinking in dreaming and the quality of dream thought have been considered hallucinatory, bizarre, illogical, improbable, or even impossible. This empirical phenomenological research concentrates on testing whether dream thought can be defined as rational in the sense of an intervening mental process between sensory perception and the creation of meaning, leading to a conclusion or to taking action. From 10 individual dream journals of male participants aged 22–59 years and female participants aged 25–49 years, we delimited (...) four dreams per journal and randomly selected five thought units from each dream for scoring. The units provided a base for testing a hypothesis that the thought processes of dream construction are rational. The results support the hypothesis and demonstrate that eight fundamental rational thought processes can be applied to the dreaming process. (shrink)
