Peter Abelard (1079–1142 ce) was the most wide‐ranging philosopher of the twelfth century. He quickly established himself as a leading teacher of logic in and near Paris shortly after 1100. After his affair with Heloise, and his subsequent castration, Abelard became a monk, but he returned to teaching in the Paris schools until 1140, when his work was condemned by a Church Council at Sens. His logical writings were based around discussion of the “Old Logic”: Porphyry's Isagoge, aristotle'S Categories and (...) On Interpretation and boethius'S textbook on topical inference. They comprise a freestanding Dialectica (“Logic”; probably c.1116), a set of commentaries (known as the Logica [Ingredientibus], c. 1119) and a later (c. 1125) commentary on the Isagoge (Logica Nostrorum Petititoni Sociorum or Glossulae). In a work Abelard called his Theologia, issued in three main versions (between 1120 and c.1134), he attempted a logical analysis of trinitarian relations and explored the philosophical problems surrounding God's claims to omnipotence and omniscience. The Collationes (“Debates,” also known as “Dialogue between a Christian, a Philosopher and a Jew”; probably c.1130) present a rational investigation into the nature of the highest good, in which the Christian and the Philosopher (who seems to be modeled on a philosopher of pagan antiquity) are remarkably in agreement. The unfinished Scito teipsum (“Know thyself,” also known as the “Ethics”; c.1138) analyses moral action. (shrink)

"And God said...." The author of this interesting study takes seriously the use of the italicized word in the biblical account of Creation. His thesis is that a modified version of the late J. L. Austin's analysis of "performatory" language can be used to reinterpret the traditional Christian claim that God "created" the world. The first half of the book is a purely philosophical analysis of self-involving language. Of particular importance is its clear distinction between, and logical mapping of, (...) performative and expressive language. In the second half this analysis is applied to biblical talk about Creation, an application which is made more valuable by the author's thorough grounding in biblical theology.—R. J. W. (shrink)

‘After it, the philosophy of perception cannot be discussed in ways it usually was discussed before.’ This is said about Sense and Sensibilia by Mr Bernard Williams in an article, ‘J. L. Austin's philosophy’, published in the Oxford Magazine of 6 December 1962. It is not quite clear what Mr Williams means by the remark. It might be understood as an endorsement of Austin's insistence that philosophers have lapsed into crudity and error through their neglect of distinctions marked (...) by the rich variety of linguistic expressions in ordinary use. But Mr Williams himself in his article makes some effective criticisms of Austin's opinion that ordinary language is a reservoir of philosophically significant distinctions, and points out also that Austin's own practice in these lectures did not exhibit any close connection between his survey of the variety of the uses of such words as ‘look’, ‘seem’, ‘appear’, and his criticism of theories of perception.

In modern approaches to phonology a lack of clarity exists on the issue of whether phonetic facts are psychological or physical realities. The results from an experiment suggest that phonetic facts can be considered as psychological realities, but with the restriction that they can take acoustical shape. More specifically, the syntactic material consisted of ambiguous French sentences of the following sort: On a tourné ce film intéressant pour les étudiants. They were spoken in disambiguating contexts, without the readers noticing the (...) ambiguities, and without context, but with the instruction to make a conscious effort to disambiguate. By tape splicing, the contexts were removed from the context-embedded sentences. Twenty-eight native speakers of French listened to the sentences and judged whether one or the other meaning had been intended by the speaker. Subjects performed significantly above chance: 60% correct identifications for context-embedded sentences, 75% for context-free sentences. Pitch-amplitude analyses were made to determine the acoustical differences involved. (shrink)

While in principle probabilistic logics might be applied to solve a range of problems, in practice they are rarely applied at present. This is perhaps because they seem disparate, complicated, and computationally intractable. However, we shall argue in this programmatic paper that several approaches to probabilistic logic into a simple unifying framework: logically complex evidence can be used to associate probability intervals or probabilities with sentences.

After describing the three main kinds of probability theories, the author presents a new logical theory of probability. Probability, for him, is a logical relation between bodies of evidence and statements. The theory is an advance over Carnap's logical theory of probability in that it is not based on a formal language with strong completeness properties. The theory is formalized in Quine's protosyntax, which has two disadvantages: first, long formulas couched in terms of a large number of defined symbols disfigure (...) the book and obscure the exposition; and secondly, it is desirable to keep our theories of inductive logic and deductive logic independent. There seems to be no reason to burden one sort of theory with the other. There is no index.--J. R. W. (shrink)

Within many approaches to the interpretation of quantum mechanics, especially modal interpretations, one singles out a particular decomposition of the state vector in order to fix the properties that are well-defined for the system. We present a novel proposal for this preferred decomposition. Given a distinguished factorization of the Hilbert space, it is the decomposition that minimizes the Ingarden–Urbanik entropy from among all product decompositions with respect to the distinguished factorization. We incorporate this choice of preferred decomposition into a framework (...) for modal interpretations and investigate in detail the extent to which it provides a solution to the measurement problem and the extent to which it ensures that measurements whose outcomes are predictable with probability 1 reveal pre-existing properties of the system under investigation.

Studies have shown that as MRI T2 relaxation time lengthens there is a shift toward more unbound or “free-water” and less partitioning of the protein/lipid molecules per unit volume. A shift toward less water partitioning or lengthened MRI T2 relaxation time is linearly related to reduced high frequency EEG amplitude, reduced short distance EEG coherence, increased long distance EEG coherence, and reduced cognitive functioning (Thatcher et al. 1998a; 1998b).

The present study applies a new method for investigating dynamic unconscious processes. The method consists of selection of words from patient interview and test protocols that in the clinicians' judgments capture the patients' conscious symptom experience and the hypothetical unconscious conflict related to the symptom, subliminal and supraliminal presentation of these words, signal analysis of event-related potentials obtained to the word presentations. Eight phobics and three patients suffering from pathological grief reactions served as subjects. A time-frequency ERP analysis revealed that (...) subjects' ERPs classified the unconscious conflict words better subliminally than supraliminally, while the reverse was true for the conscious symptom words = 2.82, p = .011). The relationship between frequency and latency revealed a similar mirror image pattern for the unconscious conflict and conscious symptom words . This method demonstrated that objective, brain-based evidence for unconscious conflict can be obtained. (shrink)
