All recent memory theories of hippocampal function have incorporated the idea that the hippocampus is required to process items only of some qualitatively specifiahle kind, and is not required to process items of some complementary set. In contrast, it is now proposed that the hippocampus is needed to process stimuli of all kinds, but only when there is a need to associate those stimuli with other events that are temporally discontiguous. In order to form or use temporally discontiguous associations, it (...) is essential to maintain some memory of the first component until the second component has occurred. When the temporal gap to he spanned is small, and the number of items to be temporarily retained is low, a limited-capacity, short-term store is sufficient to allow associations to be formed. Such a store is presumed to operate in parallel with the hippocampus in normal animals. Hippocampal damage disrupts a much higher-capacity store that has a slower decay rate, and so leaves animals with only a very limited ability to form temporally discontiguous associations. Hippocampal damage, however, is not held to affect the long-term storage of associations of any kind, if they can be formed. Analyses of both new and existing data are presented to show that by classifying tasks in terms of the need to use a temporary memory store to retain temporally discontiguous information one can cut right across existing classifications as well as achieve a better fit to the data. The hippocampus thus seems best described as a high-capacity, intermediate-term memory store. (shrink)

Professor Lewis and I have some important differences of opinion regarding the identity and distinctness of conscious persons, which it will be well to try to clarify on the present occasion, first of all by enumerating a number of points on which we are, I think, in agreement. Both of us believe in the existence of individual persons, each of whom can be said to live in a ‘world’ of his own intentional objectivity, a world ‘as it is for him’, (...) which differs in a considerable extent, both in content and emphasis, from the world as it is for anyone else. Both of us further believe that all these intentionally objective worlds for a large part coincide in content, and are in fact excerpted from a more comprehensive real world which is common to us all, and which, in addition to in some sense including all such intentionally objective worlds, also includes many real material objects which exist regardless of our intentionality, and which further includes our own material bodies, which appear in so central a manner in each of our intentionally objective worlds. Both of us believe in matter as a transcendent reality, as well as an intentional object, and are content to accept the dicta of science as to the most probable view of its structure. We are in fact quite Cartesian and Lockean in our belief in the primary and secondary qualities of matter. We believe further that our intentional subjectivity is geared causally into our material objectivity, and that the gearing takes place, in some inscrutable manner, in our nervous systems. We both also believe that our intentional subjectivity transcends bodily mechanisms and instrumentalities, and can be liberated from the latter, but that, when thus liberated, our subjectivity may still affect some sort of an intentionally objective material body such as we wear in dreams, a body in which it will manifest itself to itself and to others much as we do in our dreams and fantasies.

This volume is a collection of my essays on philosophy of logic from a phenomenological perspective. They deal with the four kinds of logic I have been concerned with: formal logic, transcendental logic, speculative logic and hermeneutic logic. Of these, only one, the essay on Hegel, touches upon 'speculative logic', and two, those on Heidegger and Konig, are concerned with hermeneutic logic. The rest have to do with Husser! and Kant. I have not tried to show that the four logics (...) are compatible. I believe, they are--once they are given a phenomenological underpinning. The original plan of writing an Introduction in which the issues would have to be formulated, developed and brought together, was abandoned in favor of writing an Introductory Essay on the 'origin'- in the phenomenological sense -of logic. J.N.M. Philadelphia INTRODUCTION: THE ORIGIN OF LOGIC The question of the origin of logic may pertain to historical origin (When did it all begin? Who founded the science of logic?), psychological origin (When, in the course of its mental development, does the child learn logical operations?), cultural origin (What cultural - theological, metaphysical and linguisti- conditions make such a discipline as logic possible?), or transcendental constitutive origin (What sorts of acts and/or practices make logic possible?).

The aim of this paper is to give a characterisation of religion and the Religious Spirit, basing itself on the Platonic assumption that there are Forms, salient jewels of simplicity and affinity, to be dug out from the soil of vague experience and cut clear from the confusedly shifting patterns of usage, which will give us conceptual mastery over the changeable detail in a given sector. It will further be Platonic in that it will not seek to discount the deep (...) gulfs between the species into which religion qua genus divides itself, i.e. its theistic, polytheistic and atheistic subvarieties, taking it to be of the essence of a true genus to extend itself over mutually exclusive species, only being what it is by including in its sense the alternatives which are thus mutually exclusive. And my treatment will be Platonic, thirdly, in that it will endeavour to delimit the Religious Spirit by, on the one hand, setting it over against what it excludes, all purely this-world talk and life which is quite irreligious, and by, on the other hand, opposing it to forms of talk and life which fall short of it in various ways or which deviate from it variously, thereby likewise contributing to our understanding of what it is. The practice of Plato, which could study the deviations from his ideal city in order to confirm his notion of its structure and excellence, and which also paired every ideal pattern with its opposite— piety with impiety, justice with self-interested tyranny, etc.—is plainly one to be followed: Plato, as we know from a citation from his contemporary Hermodorus in one of the Aristotelian commentators, always set beside the ‘in itself’ of the pure Form the deviant and the wholly negative which were nonetheless part of its sense. Religion will therefore stand before us as a target that it is possible to fall short of or miss altogether as well as to hit squarely, and we shall try by a series of glancing darts to end by hitting it squarely.

This is a very valuable study of the relations, as regards affinity and mutual influence, of two major philosophers who are now more and more being assessed at what we may hold to be their immense true worth. Both were philosophers who brought a form of Platonic realism, quite out of fashion at the time, into their interpretation of logical and mathematical concepts and principles, and who moved away from the psychologistic approaches which see such concepts and principles merely as (...) a set of forms and rules which govern our actual human thinking and its linguistic expression, and whose normative or standard-fixing aspects have their roots in the mere way in which our minds work and the mere ways in which the actual world fits in with their workings. But both thinkers, at a higher level, moved on to a view in which something like a transcendental Kantian Reason served as the ultimate foundation both of the forms and guiding principles of referential thought and of the factual empirical world whose structure this thought tries to encompass and to articulate. Both philosophers further seek in the mediating concept of Sinn or sense, as closely connected with the uses of language as with the objective matters with which language deals, the link between thought and other subjective orientations, on the one hand, and the various objective matters with which thought and language are concerned. Both thinkers, however, display great obscurities at certain points in the working out of their thoughts, by which obscurities their relation to one another is also at certain points rendered obscure.

Renowned philosopher J. N. Mohanty examines the range of Indian philosophy from the Sutra period through the 17th century Navya Nyaya. Instead of concentrating on the different systems, he focuses on the major concepts and problems dealt with in Indian philosophy. The book includes discussions of Indian ethics and social philosophy, as well as of Indian law and aesthetics.

Professor Findlay in this book, originally published in 1961, set out to justify, and to some extent carry out, a ‘material value-ethic’, ie. A systematic setting forth of the ends of rational action. The book is in the tradition of Moore, Rashfall, Ross, Scheler and Hartmann though it avoids altogether dogmatic intuitive methods. It argues that an organised framework of ends of action follows from the attitude underlying our moral pronouncements, and that this framework, while allowing personal elaboration, is not (...) a matter for individual decision. The relations connecting our fundamental value-judgements with one another, and the frames of mind behind them, are not rigorously deductive but are sufficiently compelling to be called logical. Something of a ‘transcendental deduction’ of a well-ordered family for our basic heads of valuation is both possible and necessary. The work is further critical of the notion of obligation which has been extended far beyond legal contracts and understandings. The book also contains a chapter on religion. (shrink)

In this revolutionary study of the philosophical problems of language, J.N. Hattiangadi offers a new approach which simultaneously solves several venerable conundrums in the origin and development of language and thought. His argument includes acute criticisms of the later Wittgenstein's theory of language use, Quine's approach to subjunctive conditionals, Kripke's analysis of proper names, and Chomsky's conjecture of an innate universal grammar.

The "historicity" of ideas can be reconciled with their rationality without recourse to relativism if we adopt the following view: The intellectual standards of a scientist are to be found in his intellectual situation, which is a debate underlying problems which discriminate between rival views. There is therefore no circularity between the currently accepted views and the currently accepted standards of judging a theory. debate).

As a graduate student it was with great pleasure that I learned that John Watkins had decided to thank me publicly for helping him with a paper on Kuhn’s view.1 The help, such as I could give, was in Popper’s seminar, twenty-five years ago. Watkins himself, and several others, contributed much more to the seminar than I did. (The seminar was run on the principle — to repeat J.O. Wisdom’s quip — “thou shalt not speak whilst I interrupt”). Watkins was (...) not just kind but generous in thanking me and I appreciated it very much then, as a mere graduate student. But over the years, I find that I appreciate it even more, especially as I compare it with practice common among philosophers. It is ironic that by the time Watkins’ paper appeared (something resembling his view had by then already become the official reading of Kuhn’s views among philosophers of science) my own views about Kuhn’s book had changed.

The idea that deep brain stimulation (DBS) induces changes to personality, identity, agency, authenticity, autonomy and self (PIAAAS) is so deeply entrenched within neuroethics discourses that it has become an unchallenged narrative. In this article, we critically assess evidence about putative effects of DBS on PIAAAS. We conducted a literature review of more than 1535 articles to investigate the prevalence of scientific evidence regarding these potential DBS-induced changes. While we observed an increase in the number of publications in theoretical neuroethics (...) that mention putative DBS-induced changes to patients’ postoperative PIAAAS, we found a critical lack of primary empirical studies corroborating these claims. Our findings strongly suggest that the theoretical neuroethics debate on putative effects of DBS relies on very limited empirical evidence and is, instead, reliant on unsubstantiated speculative assumptions probablyin lieuof robust evidence. As such, this may reflect the likelihood of a speculative neuroethics bubble that may need to be deflated. Nevertheless, despite the low number of first-hand primary studies and large number of marginal and single case reports, potential postoperative DBS changes experienced by patients remain a critical ethical concern. We recommend further empirical research in order to enhance theoretical neuroethics work in the area. In particular, we call for the development of better instruments capable of capturing potential postoperative variations of PIAAAS. (shrink)

This is a multi-disciplinary exploration of the history of understanding of the human mind or soul and its relationship to the body, through the course of more than two thousand years. Thirteen specially commissioned chapters, each written by a recognized expert, discuss such figures as the doctors Hippocrates and Galen, the theologians St Paul, Augustine, and Aquinas, and philosophers from Plato to Leibniz.

Jaspers' is an existentialist system, but this does not mean that it is an elaboration of a private and virtually incommunicable vision. Just as surely as the metaphysicians of the past and of those continuing traditions where such problems are taken seriously, his concern is with Being. He does not mean to talk about Being from a "standpoint" so esoteric, elusive and doctrinaire that neither Being nor the "standpoint" is really intelligible. On the other hand the program is not that (...) of formulating the system of systems, the all-comprehending system. In his own terms it is a matter of "systematic"--of the delineation and analysis of the structure of Being, where 'delineation' is ultimately elucidation and not 'objective analysis'. Now whether or not the latter distinction arouses any enthusiasm, the intent is to lay bare the character and structure of being; and this intent will be honored except in the most doctrinaire positivistic--both logical and theological--circles.
