‘Mental processes are brain processes’ is not a logically necessary truth, but nevertheless certain logical conditions must be fulfilled if it is to be a candidate for the role of contingent truth. Not just anything can, conceivably, be contingently identical with anything else: a play cannot be identical with its copies, nor beauty with a beautiful object. The propagation of light may be electromagnetic radiation, but it cannot conceivably be the tri-section of a right-angle. In this paper I shall be (...) concerned with the general question of whether there are any logical barriers to mind-body identification, and I shall approach this via the more particular question of whether the mental processes of persons can conceivably be identical with the physiological processes of brains. It is my contention that identity theorists, by concentrating their attentions upon what were once called the “lower” parts of the soul rather than upon “higher” parts which are more typical of human persons, have paved a logical way for themselves which is artificially straight.

In this paper I shall deal with a new form of Optimism. Rationalists once believed that it was mistaken to suppose that a world without God is a meaningless one; material progress along with the improvement of men and their institutions, indefinitely protracted, ensured that life was meaningful. More recently it has become fashionable to claim that the pessimist, the cosmic mourner, is not mistaken at all, but rather incoherent. It is not that there is no answer to his question (...) but rather that no sensible question has been asked—at least in the terms in which he poses it. The latter qualification is necessary, for no one is denying that people's lives may either possess or lack meaning. Rather what is being denied is that life as a whole, tout court and without limitation, can be said either to have or not to have sense. One cannot, it is argued, regret what could not, logically, be otherwise, and since nothing could possibly count as endowing the cosmos as a whole with meaning it is not logically possible for the cosmos as a whole to have, or not to have, meaning. The regret evinced by the pessimist becomes, therefore, a pseudo-regret. ‘… it is perverse writes Ayer, ‘to see tragedy in what could not conceivably be otherwise.’ Just as a pseudo-problem is one for which there could, logically, be no solution, so a pseudo-regret is one in which there can be no assuagement of the regretted situation. None of this is to deny, of course, that a man can experience a state of mind which might be described as ‘cosmic anguish’, but such an experience has no cognitive value: it is a state of mind, no doubt painful for the possessor, which tells us nothing about the world beyond it. That people have confused this state of mind with a judgement about the world is understandable, but mistaken. (shrink)

Bart Streumer employs a reductio ad absurdum to show that a hyperintensional conception of properties has a multiplication problem; roughly, this conception of properties leads to the absurd result that we can multiply distinct but co-intensional properties without end. In this paper, I will explain why Streumer’s reductio fails to convince.
