In the book The Hacker Ethic and the Spirit of the Information Age (2001), Torvalds introduces his law in the prologue "What Makes Hackers Tick? a.k.a. Linus's Law", suggesting that every motivation that makes a person do something can be classified under "survival", "social life" or "entertainment".[13] As a result, he writes, progress is defined as reaching a higher category; that is, not doing a thing merely for survival, but for social reasons, and then, even better, just for fun. These correspond to levels of motivation in Maslow's hierarchy of needs.[13]
