Combining Possibilities and Negations

Combining non-classical (or sub-classical) logics is not easy, but it is very interesting. In this paper, we combine nonclassical logics of negation and possibility (in the presence of conjunction and disjunction), and then we combine the resulting systems with intuitionistic logic. We will find that Kracht's results on the undecidability of classical modal logics generalise to a non-classical setting. We will also see conditions under which intuitionistic logic can be combined with a non-intuitionistic negation without corrupting the intuitionistic fragment of the logic.     

Improbable Possibilities

Whether or not a woman can “choose” her sexuality has been subject to debate because it contests essentialist notions of sexuality as fixed and determined early in life. This article explores the variabilities among women in sexual object choice and expression and elaborates on the claim that women's sexuality is fluid. It does so by presenting a summary of interviews with women of all sexual orientations who do, in fact, experience their sexuality as a conscious choice. Their own words reveal the plasticity of sexual attractions, experiences, and identities and the more fluid sexuality that emerges as a result. The article also highlights the importance of considering cultural and historical context—specifically the contemporary feminist movement—as it affects the range of possibilities in women's construction of their sexual desire and identity.     

Practical Possibilities

Abstract: That inferences of the form "If M then S and possibly M, therefore possibly S" are invalid in possible worlds modal logics can be viewed as another fallacy of material implication. However, this paper argues that properly analyzing this and related inferences requires treating the possibility involved as a practical modality. Specifically, ordinary language propositions of the form "It is possible that M" must be understood to mean that there is a non-negligible probability of M being the case. But this entails reexamining the very idea of logical validity.     

Avoiding unbearable pain

This presentation describes the way in which defence mechanisms and resistance manifested themselves in the analysis of a man with a narcissistic personality disorder. In the course of the analysis, there were changes in the forms taken by the defence and the resistance, signalling important genetic and dynamic conditions in his life. Both represented desperate attempts to avoid the unbearably painful feelings and affects which he had experienced in his childhood, and bore witness to early and primitive defence mechanisms such as denial, splitting and projective identification. The defence can also be seen as an expression of an unconscious fear of being re-traumatised. The idealisation of the analyst in the first years of the analysis can therefore be understood as a precondition for entering into this kind of process. It also represented a defence against aggressive and homosexual feelings in the transference which first became clear during the final phase of the analysis and could then be worked through. At this point, the analyst's reactions to his own unconscious countertransference were of help in understanding what was actually going on. This analysis may also suggest that defects and trauma in the earliest years may be conducive to alexithymia, deficient contact between feelings and words, linked to the risk of developing serious psychosomatic illnesses. This may be a consequence of the fact that the child's feelings and affects were neither accepted, understood nor affirmed in words, or they may even have been met with rejection or ridicule. A connection between narcissistic personality disorders and alexithymia can possibly be seen here.     

Avoiding and seeking self-focused attention

Male and female undergraduates read aloud statements about women which were either attitudinally consistent, discrepant, or neutral relative to their attitudes toward women. Following this, they were given the opportunity to choose to wait in front of a mirror or a nonreflecting wall. Subjects engaging in attitudinally discrepant behavior avoided self-focusing stimuli; those engaging in attitudinally consistent behavior sought contact with self-focusing stimuli. Intermediate tendencies to seek or avoid self-focused stimuli were demonstrated by subjects reading attitudinally neutral material. The theory of objective self-awareness was extended by demonstrating that self-focusing stimuli are not just avoided in response to negative discrepancies, but are sought out in response to attitude-behavior consistencies.     

Avoiding Infinite Masses

The examples of dynamic supertasks analyzed to date in the philosophical literature, in which both determinism and the classical laws of conservation of energy and momentum are violated, all share the important limitation of requiring material systems of infinite mass. This paper demonstrates that this limitation is not necessary. This has important consequences for the scope and meaning of such violations.
