# Quote — Robert A. Heinlein, Job: A Comedy of Justice

> For a creature to act out its own minor art, the rules under which it acts must be either known to it or be such that the rules can become known through trial and error — with error not always fatal. In short the creature must be able to learn and to benefit by its experience.
