Phillip E. Johnson (born 1940) is a retired UC Berkeley law professor and author. He became a born-again Christian as a tenured professor. He is considered the father of the intelligent design movement, which criticizes the theory of evolution, and promotes intelligent design, as an alternative. Johnson also denies the predominant scientific view that the human immunodeficiency virus (HIV) is the sole cause of AIDS (see AIDS reappraisal). The scientific community dismisses both notions as pseudoscience.
