John Allen Paulos, Vintage, 1985
Humourous overview of philosophy. Not his finest work.
Spoiled for me by his dismissal of Dawkin's selfish gene theory.
"One might argue that it is not our genes that are selfish but a particular chemical bond in the genes. Our actions are not determined by our genes after all, but by a chemical bond in them that is trying to perpetuate itself.
Reductio ad adsurdam[sic]."
