Give me a dozen healthy infants, well-formed, and my own specified world to bring them up in and I'll guarantee to take any one at random and train him to become any type of specialist I might select – doctor, lawyer, artist, merchant-chief and, yes, even beggar-man and thief, regardless of his talents, penchants, tendencies, abilities, vocations, and race of his ancestors... (1930, p.82)Now, I don't really like Watson. I think he derailed what was supposed to be a brilliant next step in the development of American Philosophy, and turned into something trite and hollow. Also, he was clearly an asshole, both as a member of the profession and as a human being.
That said, I am certainly willing to defend this claim. I think, when it is examined carefully, that it is quite reasonable, and that history has proved him right.
