(January 11, 1842–August 26, 1910), was a philosopher and psychologist, considered by some to be the father of modern psychology. A Harvard professor, his theory of ethics, called pragmatism, considered the distinction between truth and falsity, even in the area of religion and morals, not as important as solving problems.2820 His works include The Principles of Psychology, 1890; The Varieties of Religious Experience, 1902; Pragmatism, 1907. Contemporary social engineering of psychological attitudes has been influenced by his thought. William James stated:
There is nothing so absurd but if you repeat it often enough people will believe it.2821
