Quote by John B. Watson
"Every behavior can be traced to its environmental source."
More from John B. Watson
"Psychology as I see it is a purely objective experimental branch of natural science. Its theoretical goal is the prediction and control of behavior; and its practical goal is to help men and women."
"The behaviorist refuses to see any dividing line between man and brute. The behavior of man, with all of its refinement and complexity, forms only a part of the behaviorist's total scheme of investigation."
"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."
"There is no such thing as an inheritance of capacity, talent, temperament, mental constitution and characteristics. These things again depend on training that goes on in the early years."
