I agree with this. It's a pity that Engels spent so much of his time on keeping abreast of the physical sciences, rather than paying attention to the statistical literature.
There's a very interesting account of the statisticians' debate about free will in Ian Hacking's "The Taming of Chance" (1990, Cambridge UP), for those who are interested.
