Semantic Puzzles

[from Joel, image added by Ira]
The philosopher Wittgenstein believed that there are no philosophical problems, only semantic puzzles. David Sussman, our speaker at Friday's [The Villages, FL] philosophy club meeting presented a talk about humanism. Among other things, he presented the philosophical problem that a mechanistic approach to the human mind excludes the possibility of free will and yet we believe we have free will. He proposed that perhaps a person cannot be blamed for what is an inevitable consequence of brain machinery. I believe this is just an example of a semantic puzzle. Can you state the puzzle and find the solution?

Wittgenstein's Poker

[from Joel - Wittgenstein's Poker and Wittgenstein links and image added by Ira] This is not a book about an Austrian variation on Texas Hold'em. It's about the philosophers Popper and Wittgenstein. Has anyone read the book? It's ingeniously based upon a ten minute argument between Popper and Wittgenstein that took place at Cambridge in 1946 and during which Wittgenstein is purported to have threatened Popper with a hot poker. The authors use the controversy as a means of sketching both philosophers and the various witnesses. Expanding about this nucleus, they comment upon the entire state and history of European philosophy during the first half of the twentieth century. I haven't finished the book yet, but so far it's a good read.
