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 located, unextended, incorporeal, capable of acting on bodies, dependent upon body, 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. (shrink)

I first met Parmenides – together with Xenophanes, Heraclitus, and the other great Presocratics – in a German translation by Wilhelm Nestle, famous as the editor of the later editions of Zeller's magnum opus. I was 15 or 16 years old, and I was overwhelmed by the meeting. The verses that I liked best were Parmenides' story of Selene's love for radiant Helios . But I did not like it that the translation made the moon male and the sun female (...) , and it occurred to me to give the couplet in German a title like ‘Moongoddess and Sungod’, or perhaps ‘Selene and Helios’, in order to rectify the genders. So I began fiddling about with the translations. The volume, which I still possess, shows many traces of this. (shrink)
