This work provides a welcome antidote to some of the distortions and biases which the two dominant schools of Anglo-American philosophical thinking, logical positivism and ordinary language analysis have introduced into the philosophy of history in the past three or four decades. In particular, it challenges two powerful stereotypes: that philosophy and history are conceptually independent of each other; and that there exists a sharp division between "analytical" (reputable) and "speculative" (disreputable) philosophy of history. By offering and defending his own (...) conception of philosophy, the author seeks to show that there is indeed common ground between philosophy and history, that speculative philosophy of history lies between philosophy and history, not because it is neither philosophy nor history, but because it is both philosophy and history. Originally published in 1970. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

Opinion surveys were taken in an effort to determine the philosophical beliefs of students beginning philosophy. Correlated sets were made of those who took the survey before and after a first course in philosophy; and opinion shifts noted. The acquired information may be of interest to people in various disciplines. The authors tested the semantic usage of certain epistemological terms, the change in religious beliefs, the degree of consistency between general skepticism and particular knowledge claims. Finally, the authors proposed a (...) consistency test for the measure of the extent to which a sample of students “clarified their beliefs,”; and attempted to measure their own pedagogical efficiency with reference to this test.

Previous criteria of narrative coherence have failed to come to terms with narrative intelligibility. The principle of chronology is only a negative criterion. The one entity-one story criterion, which requires every episode to~ refer to one and the same entity, fails both in its positive and negative forms. The Aristotelian concept of necessary connection is useless for historians because there are no natural beginnings or endings in history. Yet genetic relationships in narrative, though they cannot be reduced to causal or (...) probabilistic relationships, do give coherences. History becomes science when historians transform stories into histories by seeking the mechanisms which underlie the genetic relationships between historical incidents. The construction of history in narrative form does not, therefore, cut the historian off from science, as positivists contend. (shrink)

Hart and Honoré contend, in their book Causation in the Law, that causal appraisals in everyday life and in the law can be made, with justifiable confidence, without appealing to relevant general laws; that in order to grasp the workings of causal notions in everyday life and the law, it is sufficient to note that causes are events which interfere with or intervene in the course of events which would normally have taken place. This thesis is criticized on the ground (...) that what purport to be purely causal appraisals are hopelessly vulnerable to moral considerations, especially when such appraisals are presumed to take place in complete independence of scientific theory.

Light can kill the photoreceptors of the eye, not only very bright direct sunlight, but more moderate illumination if the light is present continuously. Recent experiments show that rod apoptosis can be triggered by strong and constant activation of transduction, and that death can be prevented if transduction is inhibited even though the eye is illuminated. Vitamin A deficiency and genetically inherited diseases, such as some forms of retinitis pigmentosa and Leber congenital amaurosis, appear to kill like this: transduction is (...) activated at a high rate and continuously, and this causes the rods to die. Why does transduction kill? Our best guess is that continuous activation produces a prolonged lowering of the Ca2+ concentration, which is also thought to kill neurons in tissue culture and during the development of the nervous system. To prevent death in constant light, rods have evolved protective mechanisms including modulation of channels and ion transport to keep the Ca2+ from going too low. Prolonged light exposure also causes migration of transduction proteins from one part of the cell to another and a reversible shortening of the rod outer segments, the part of the cell that contains the pigment rhodopsin. All of these mechanisms are at work in the normal eye to reduce transduction and prevent the Ca2+ concentration from dropping too low for too long a time. That most of us retain our vision our entire lives is a testament to their effectiveness. BioEssays 28: 344–354, 2006. © 2006 Wiley Periodicals, Inc. (shrink)

C-minimality is a variant of o-minimality in which structures carry, instead of a linear ordering, a ternary relation interpretable in a natural way on set of maximal chains of a tree. This notion is discussed, a cell-decomposition theorem for C-minimal structures is proved, and a notion of dimension is introduced. It is shown that C-minimal fields are precisely valued algebraically closed fields. It is also shown that, if certain specific ‘bad’ functions are not definable, then algebraic closure has the exchange (...) property, and for definable sets dimension coincides with the rank obtained from algebraic closure.

This second companion paper to a logico-mathematic, structural methodology and its findings address theoretical issues underlying sub-literal phenomena. The concept of a “cognitive psycho-dynamics” is introduced. In addition, research on masked priming and automatic activation of “chronic goals and motives” schemata are presented as initial and partial explanatory theoretical bases. Corroborating findings from fMRI and other neurological research suggest that some of the cognitive operations are biologically based. A biological evolutionary framework is then presented to explain the origin and development (...) of SubLit cognition and lexical referents. Implications are discussed throughout. (shrink)

In this first of three papers, a novel cognitive and psycho-linguistic non metric or non quantitative methodology developed for the analysis and validation of unconscious cognition and meaning in ostensibly literal verbal narratives is presented. Unconscious referents are reconceptualized as sub-literal referents. An integrally systemic, structural, and internally consistent set of operations is delineated and instantiated. The method is related to aspects of two models. The first is logico-mathematic structure; the second is linguistic syntax. After initially framing the problem that (...) the method addresses, along with some theoretical implications, historical precursors are briefly outlined. The method presents novel cognitive and linguistic operations. Though the method raises a number of issues of theory, research, and methodology, and makes a contribution to these areas, it stands independently, qua method. (shrink)

In this first of two companion papers to a logico-mathematic, structural methodology , a meta-level analysis of the non metric structure is presented in relation to critiques based on standard experimental, statistical, and computational methods of contemporary psychology and cognitive science. The concept of a non metric methodology is examined as it relates to the epistemological and scientific goals of experimental, statistical, and computational methods. While sharing in these goals, differences and similarities between the two methodological approaches are outlined. It (...) is argued that typical experimental methods are not sufficient to extract and validate semantic information in verbal narratives. It is further suggested that a logico-mathematic, structural methodology can yield invariant law-like cognitive processes by careful methodological control of the specific case — instead of those found by current methods that produce “laws” based on statistical frequency. Lastly, the issue of experimental manipulation in relation to the logico-mathematic, structural methodology is examined. (shrink)

We study the Vapnik–Chervonenkis density of definable families in certain stable first-order theories. In particular, we obtain uniform bounds on the VC density of definable families in finite $\mathrm {U}$-rank theories without the finite cover property, and we characterize those abelian groups for which there exist uniform bounds on the VC density of definable families.
