Additional quotes by John Horton Conway

Lucretius... was an atomist, a follower of Epicurus. The original people who invented the atomic theory were and Democritus. ...Lucretius is discussing ...atoms ...he says, "at quite indeterminate times and places they swerve" ...because it allows for human free will... and "if the atoms never swerve... what is the source of the free will possessed by living things throughout the earth?" He says, "Although many men are driven by an external source, and often constrained involuntarily to advance or rush headlong, yet there is in the human breast something that can fight against it and resist it... So also in the atoms you must recognize the same possibility. Besides weight and impact, there must be a third cause of movement, the source of this inborn power... due to the slight swerve of the atoms... since nothing can come out of nothing." And then he goes on to say, "the fact that the mind itself has no internal necessity to determine its every act, this is due to the slight swerve of the atoms at no determinate time and place."

Laplace... wrote Mécanique céleste discussing the motion of the planets. ...[O]ne ...reason why ...determinacy got its ...impetus from the development of science, was that Newton's theory of gravitation ...was entirely deterministic. It left no room for freedom. ...Laplace, who did a lot of work on Newtonian ...theory says ...An intellect ...[or] intelligence, which knew ...where all the particles were at some moment and how fast they were moving, and so on, that every single thing could be known to that intelligence, provided a ...good calculator. ...It could reason out exactly what was going to happen in the future. ...It's the strongest ...assertion of determinism in the scientific literature. I don't believe it for one moment..!

It's one of the things I most admire about Simon Kochen, my co-author, that... in August 2006, we'd been talking about this... for years... Suddenly the scales fell away, that had been obscuring the thing, and I said... "We've proved if we have free will, so do the particles" and he... said "Yes... this means that my stuff with Ax is all nonsense, doesn't it?"
