My friends have been asking me what The Hitchhiker’s Guide the Galaxy is about. Several things come to mind: survival; discovery; the pursuit of happiness; the cycle of life; philosophy; and other vague ponderous issues.
But the real answer is this: it is about finding questions to answers (not vice versa).
What the hell does that mean? Easy. Spend a couple hours reading the short, 200-page book, and it will all be clear.
