Bertram Morris

Bertram Morris

Bertram Morris (1908-1981) was born in Denver.  Educated at Princeton and Cornell, he taught at the University of Colorado from 1947 until his retirement in 1977.  He published books including The Aesthetic ProcessPhilosophical Aspects of Culture, and Institutions of Intelligence.

Bertram Morris is remembered as much for his committed involvement in the social issues of his community as for his scholarly work.  In 1953, he began an outreach program at Manual High School in Denver that still continues.  In 1975, he was given a special award by the American Civil Liberties Union of Colorado for his efforts on behalf of academic freedom and his work to improve conditions at the Boulder County Jail.

As an expression of admiration and gratitude, the Philosophy Department established this Colloquium when Bertram Morris retired in 1977.

Topic: Cultural Property and the Ethics of War

April 27-28, 2017

Topic: Metaphysics and Its History

March 11-12, 2016

The topic of this year's colloquium is metaphysics and its history. It will be a crossover workshop bringing together contemporary metaphysicians working on issues with a rich history and historians of metaphysics working on issues of great contemporary significance, aiming to encourage a dialogue between what are arguably continuous lines of inquiry. To that end, historians will comment on non-historians and non-historians on historians.
