C. Terry Warner, a philosophy professor at Brigham Young University until his retirement, has made unprecedented strides in the area of self-deception, especially as it relates to social interactions. I have seen no one else treat his subject better. Studying self-deception without talking about Terry Warner would be a little like studying physics without talking about Einstein. I am greatly indebted to him for my knowledge in this area and will forever be grateful I was ever able to study under him.
