The Logical Leap Quotes

“Induction is the process of inferring generalizations from particular instances. The complementary process of applying generalizations to new instances is deduction. The theory of deductive reasoning was developed by Aristotle more than two millennia ago. This crucial achievement was a start toward understanding and validating knowledge, but it was only a start. Deduction presupposes induction; one cannot apply what one does not know or cannot conceive. The primary process of gaining knowledge that goes beyond perceptual data is induction. Generalization—the inference from some members of a class to all—is the essence of human cognition.”
