The Future of Freedom Foundation has links to bios of Herbert Spencer.

You know, the "Social Darwinism" guy. Although Will Durant (in The Story of Philosophy) says he's really a Social LaMarckist. And in the case of Society, I'd say that's pretty true. And also kinder than "the survival of the fittest". It implies that we are capable of learning as we grow older, and passing that knowledge on to our children.

I think Spencer's greatest quote is "the effect of shielding men from (...searching Freedom's Nest...)..." AH! "The ultimate result of shielding men from the effects of folly is to fill the world with fools."

Oops! I linked the wrong book up there. Will Durant's book is this one.
