Leonard Peikoff is a Canadian American philosopher. He is a central figure in a belief system called Objectivism. This philosophy is based on the ideas of the writer Ayn Rand. Peikoff was a close associate of Rand for many years. She eventually named him the legal heir to her estate. Today, he manages her copyrights and her intellectual legacy. He also co-founded the Ayn Rand Institute (ARI) in 1985.

Peikoff's academic journey began in Winnipeg, Manitoba, Canada. He was born on October 15, 1933. His father, Samuel Peikoff, was a surgeon. His mother, Bessie, was a band leader. Peikoff initially studied as a pre-med student at the University of Manitoba. However, meeting Ayn Rand at age 17 changed his path. He moved to New York City to study philosophy at New York University. He earned his BA, MA, and PhD degrees there between 1954 and 1964. His doctoral dissertation focused on the metaphysical status of the law of noncontradiction.

During his student years, Peikoff was part of a group called "The Collective." This group included Nathaniel Branden, Alan Greenspan, and Barbara Branden. They met frequently in Rand's Manhattan apartment. They discussed politics and read her upcoming novel, *Atlas Shrugged*. In 1958, the Nathaniel Branden Institute (NBI) was founded to teach Objectivism. Peikoff served as one of its first lecturers. He taught courses on the history of philosophy to large audiences. These lectures were often recorded and sold for many years.

Peikoff has contributed significantly to the development of Objectivist epistemology. Epistemology is the study of how we know things. His discussions with Rand helped her write *Introduction to Objectivist Epistemology*. Peikoff later expanded this work using transcripts from her philosophy workshops. He also wrote *Objectivism: The Philosophy of Ayn Rand* in 1991. This book provides the first comprehensive presentation of the system. In his 2012 book, *The DIM Hypothesis*, he explains three ways of cognitive integration. These are disintegration, integration, and misintegration.

One major area of Peikoff's work is the theory of induction. Induction is a way of reaching general conclusions from specific observations. In *The Logical Leap: Induction in Physics*, Peikoff and David Harriman argue that induction is a vital science. They claim that scientific knowledge is contextual. This means scientific claims are true based on the available evidence. They should only be changed if new evidence appears. Peikoff believes this process makes truth in science as objective as physics.

Peikoff's political views center on laissez-faire capitalism. He argues that the government should have a very limited role. He describes this as a "night-watchman state." In this system, the government only protects people from force and fraud. He opposes taxation, public education, and business regulations. He also holds specific views on social issues. He supports abortion rights but disagrees with the term "pro-choice."

There have been important debates within the Objectivist movement. Peikoff views Objectivism as a "closed system." This means the philosophy consists only of the principles Rand articulated. He believes any disagreement with these principles is a departure from Objectivism. This caused a split with philosopher David Kelley. Kelley argued for an "open system" that could evolve. This disagreement led Kelley to found The Atlas Society in 1990.

Peikoff has also managed complex legal matters regarding Rand's work. He inherited many of her manuscripts. A dispute arose with the Library of Congress over certain pages. The library claimed some manuscripts were U.S. government property. After a complaint from the Department of Justice in 2000, Peikoff released the pages. Beyond books, Peikoff has used many media to share ideas. He hosted a nationally syndicated radio show from 1995 to 1999. He also hosted a podcast from 2007 to 2016.
