E Prime
D. David Bourland, Jr. first suggested E Prime in 1965. Bourland had studied the discipline (way of thinking) of General Semantics. The main idea of General Semantics is that people can only know what they observe and experience when they see, hear, touch, taste, smell, think, and feel, and furthermore, that what they observe and experience can affect how they observe and experience in the future. Because each person has different experiences throughout their lives, they interpret their experiences differently.
