We distinguish three different readings of the intuitionistic notions of validity, soundness, and completeness with respect to the quantification occurring in the notion of validity, and we establish certain relations between the different readings. For each of the meta-logicalnotions considered we suggest that the "most natural" reading (which is not the same for all cases) is precisely the one which is required by the recent intuitionistic completeness theorems for IPC.

It is traditionally believed that cerebral activation (the presence of low voltage fast electrical activity in the neocortex and rhythmical slow activity in the hippocampus) is correlated with arousal, while deactivation (the presence of large amplitude irregular slow waves or spindles in both the neocortex and the hippocampus) is correlated with sleep or coma. However, since there are many exceptions, these generalizations have only limited validity. Activated patterns occur in normal sleep (active or paradoxical sleep) and during states of anesthesia (...) and coma. Deactivated patterns occur, at times, during normal waking, or during behavior in awake animals treated with atropinic drugs. Also, the fact that patterns characteristic of sleep, arousal, and waking behavior continue in decorticate animals indicates that reticulo-cortical mechanisms are not essential for these aspects of behavior.

A study of the place of human sexuality in religious systems indicates a possible universal stress on sexual attraction. This could be explained by using the theories of Richard Dawkins and other sociobiologists: the philandering male and the coy female express the best strategies for the survival of the “selfish gene.” Closer analysis of four religious systems throws doubt on these theories. In some systems the strategies are contradicted while in others there is stress on cooperative restraint rather than on (...) survival through selfish propagation. The principal objection to the sociobiological approach is its assumption of conflict between the sexes. (shrink)
