Philip Johnson is a professor of law at the University of California - Berkley. Although his specialty is law, he's been involved in the discussion of evolution and creation for many years. His interests are in clarifying the terms that are used in the discussion and asking people to present their arguments in a way that allows for objective evaluation; without the usual presumptions we tend to have.
In this video, Johnson is asked a series of questions on evolution. He does a commendable job of bringing clarity to the terms, revealing hidden assumptions we might have. Johnson's book Darwin On Trial is a competent, thorough examination of the subject.
