The Logical Leap

A groundbreaking solution to the problem of induction, based on Ayn Rand's theory of concepts.

Inspired by and expanding on a series of lectures presented by Leonard Peikoff, David Harriman presents a fascinating answer to the problem of induction-the epistemological question of how we can know the truth of inductive generalizations.

Ayn Rand presented her revolutionary theory of concepts in her book Introduction to Objectivist Epistemology. As Dr. Peikoff subsequently explored the concept of induction, he sought out David Harriman, a physicist who had taught philosophy, for his expert knowledge of the scientific discovery process.

Here, Harriman presents the result of a collaboration between scientist and philosopher. Beginning with a detailed discussion of the role of mathematics and experimentation in validating generalizations in physics-looking closely at the reasoning of scientists such as Galileo, Kepler, Newton, Lavoisier, and Maxwell-Harriman skillfully argues that the inductive method used in philosophy is in principle indistinguishable from the method used in physics.Leonard Peikoff is universally recognized as the pre-eminent Rand scholar writing today. He worked closely with Ayn Rand for 30 years and was designated by her as her intellectual heir and heir to her estate. He has taught philosophy at Hunter College, Long Island University, and New York University, and hosted the national radio talk show "Philosophy: Who Needs It."
