Robert A. Heinlein Quote

There are three schools of magic. One: State a tautology, then ring the changes on its corollaries; that's philosophy. Two: Record many facts. Try to see a pattern. Then make a wrong guess at the next fact; that's science. Three: Awareness that you live in a malevolent universe controlled by Murphy's Law, sometimes offset in part by Brewster's Factor: that's engineering.


Chapter XLVIII, L'Envoi or Rev. XXII: 13 (p. 508) - The Number of the Beast (1980)
