A collection of essays on how the scientific culture shapes the advancement of science. Stephen Jay Gould, on representations of the "tree of life", is good as always (shades of his "the size of a fox terrier" essay); Oliver Sacks rambles a bit but in a thoroughly interesting way; Jonathan Miller explains the effects of hypnotism. This is probably one to borrow rather than buy, but worthwhile nonetheless.
