Replies are given to arguments advanced in this journal that claim to show that it is to nonlinear classical mechanics rather than quantum mechanics that one must look for the physical underpinnings of conscious ness..

This article begins with some brief reflexions on the definition of determinism (II), on the notion of the subject of experience (III), and on the relation between conscious experience and brain events (IV). The main discussion (V?XIII) focuses on the traditional view, endorsed by Honderich in his book A Theory of Determinism, that the truth of determinism poses some special threat to our ordinary conception of ourselves as morally responsible free agents (and also to our ?life?hopes'). It is argued that this is half right: the truth of determinism does indeed threaten certain vital parts of our ordinary conception of ourselves as morally responsible free agents. The trouble is that the falsity of determinism does not diminish the threat in any useful way. The old, natural, and recurrent mistake is to think that we would really be better off, so far as free will and moral responsibility (and our ?life?hopes') were concerned, if determinism were false. It is argued that there is no important sense in which this is true, and that the question of whether determinism is true or false is therefore of no real importance, so far as the free will debate is concerned.

When I look at the scale of the apparatus I know what it reads. Those absurdly delicate, hopelessly inaccessible, global correlations obviously vanish when they connect up with me. Whether this is because consciousness is beyond the range of phenomena that quantum mechanics is capable of dealing with, or because it has infinitely many degrees of freedom or special super selection rules of its own, I would not presume to guess. But this is a puzzle about consciousness that should not get mixed up with efforts to understand quantum mechanics as a theory of subsystem correlations in the nonconscious world. ( David Mermin 1998).

Christof Koch and Klaus Hepp, in a recent essay in this journal1, issued a challenge to “those who call upon consciousness to carry the burden of the measurement problem in quantum mechanics.” Lest absence of a response be construed as admission of a failure of the idea that consciousness can play, via quantum measurement effects, a crucial role in neurodynamics, or that this idea has been in any rational way damaged by the arguments put forth in the cited article, I respond here to that challenge.

In this book, which contains several of his key papers as well as new material, he focuses on the problem of consciousness and explains how quantum mechanics...
