Aristotle on Predication

A predicate logic typically has a heterogeneous semantic theory. Subjects and predicates have distinct semantic roles: subjects refer; predicates characterize. A sentence expresses a truth if the object to which the subject refers is correctly characterized by the predicate. Traditional term logic, by contrast, has a homogeneous theory: both subjects and predicates refer; and a sentence is true if the subject and predicate name one and the same thing. In this paper, I will examine evidence for ascribing to Aristotle the view that subjects and predicates refer. If this is correct, then it seems that Aristotle, like the traditional term logician, problematically conflates predication and identity claims. I will argue that we can ascribe to Aristotle the view that both subjects and predicates refer, while holding that he would deny that a sentence is true just in case the subject and predicate name one and the same thing. In particular, I will argue that Aristotle's core semantic notion is not identity but the weaker relation of constitution. For example, the predication ‘All men are mortal’ expresses a true thought, in Aristotle's view, just in case the mereological sum of humans is a part of the mereological sum of mortals.

Enhanced Latent Inhibition Following Compound Pre-exposure

The influence of non-reinforced exposure to compound stimuli on subsequent appetitive classical conditioning was examined in five experiments with rats as the subjects. Non-reinforced exposure to a visual stimulus retarded subsequent acquisition of conditioned responding relative to a non-pre-exposed condition (latent inhibition). If the target stimulus was pre-exposed in compound with a second (non-target) stimulus, then latent inhibition was abolished. Exposure to the non-target stimulus prior to compound exposure had varying effects on subsequent conditioning to the target: 40 exposures to the non-target stimulus resulted in latent inhibition to the target stimulus that was comparable in magnitude to that observed when the target stimulus was exposed in isolation; 120 exposures to the non-target stimulus enhanced latent inhibition to the target stimulus.     

Discontinuities in the male psyche: waiting, deadness and disembodiment. Archetypal and clinical approaches

The discontinuities of development in the male psyche that are manifested in some analyses in unconscious experiences of inner disintegration are described. Narcissism and a de-somatized relationship to their own presence are the dominant clinical presentation in these patients. The analyst sometimes experiences these analyses as 'dead', as a result of the projection of a 'dead mother' object. The question of how psychic deadness and impotence can be worked with is examined. Clinical experience with these men shows how notions associated with the puer-senex archetype can illuminate the stark realities of a patient's early experiences, particularly in how mother's presence is felt. A theoretical and clinical bridge is proposed between puer and narcissus to frame how a man may unconsciously strive against psychic fragmentation by clinging to an identification with both--in order to remain intact in the face of being caught in a pre-pubescent state which reflects the insecure attachment to mother. The author describes how patients may find a more grounded embrace of reality via the use of the analyst's empathy and a greater potency through work in the transference/countertransference. These strengthening achievements help men to begin to leave the 'dead mother' behind.     

A Preliminary Analysis of the Rorschach Records of Fifty Prison Inmates

An attempt was made to test the hypothesis that the Egocentricity Index (Exner, 1974), a ratio which incorporates pair and reflection responses, is related to self-esteem. Sixty criminal defendants referred for psychiatric evaluation were routinely administered the Rorschach. After all other testing was Completed the subjects were asked to complete the Coopersmith Self-esteem Inventory. Results found no significant relationships between the Egocentricity Index and self-esteem as measured by the Coopersmith. It was recommended that the Egocentricity Index not be used as a measure of self-esteem, until research evidence to support its use in this manner is provided.     

How Resilient Are Our Attempts to Explore the Mind of Another? Commentary on Dr. Karlen Lyons-Ruth's Article

This article discusses whether attachment experiences may shape the quality and consistency of individuals' attempts to explore the minds of significant others, a process Dr. Lyons-Ruth refers to as intersubjectivity. Specific commentary focuses on whether individuals with an insecure or disorganized attachment organization continue to engage in intersubjective processes over the lifespan. To help illuminate these questions, the work of the University College London group on reflective functioning is discussed and directions for future research are suggested.
