Key points Argues that mind and physical forces share at least six properties (being located, unextended, incorporeal, able to act on bodies, dependent on bodies, and influenceable by bodies), and that understanding the nature of forces is essential to the mind-brain problem. Popper stresses the relative autonomy and indeterminism of mind, links indeterminism to a theorem of Hadamard, and criticizes the computer theory of mind and the Turing test.

Abstract

In this paper Popper formulates and discusses a new aspect of the theory of mind. This theory is partly based on his earlier developed interactionistic theory. It takes as its point of departure the observation that mind and physical forces have several properties in common, at least the following six: both are (i) located, (ii) unextended, (iii) incorporeal, (iv) capable of acting on bodies, (v) dependent upon body, (vi) capable of being influenced by bodies. Other properties such as intensity and extension in time may be added. It is argued that a fuller understanding of the nature of forces is essential for the analysis of the mind-brain problem. The relative autonomy and indeterministic nature of mind is stressed. Indeterminism is treated in relation to a theorem of Hadamard. The computer theory of mind and the Turing test are criticized. Finally the evolution of mind is discussed.
