A classic book meets several criteria: it has stood the test of time, it offers insight into the human condition, and it has influenced later writers and thinkers. Many classics were controversial in their day. Mary Shelley's Frankenstein was dismissed by some critics in 1818, yet it invented an entire genre. Herman Melville's Moby Dick sold poorly during his lifetime but is now considered one of the greatest novels in the English language.
