The Physiology and Physics of the Free Will Problem

  • J. C. Eccles
Part of the Studies in the Natural Sciences book series (SNS, volume 6)


I will begin by brief reference to the philosophical basis of my discussion. I refer to the trialist philosophy that has been developed by Sir Karl Popper (1972) in his recent book “Objective Knowledge.” As illustrated in Fig. 1, everything in existence and in experience is subsumed in one or other of three worlds: World 1, the world of physical objects and states; World 2, the world of states of consciousness and subjective knowledge of all kinds; World 3, the world of man-made culture, comprising the whole of objective knowledge. Furthermore it is postulated that there is interaction between these worlds. There is reciprocal interaction between Worlds 1 and 2, and between Worlds 2 and 3 via the mediation of World 1.
