給我一打健康的嬰兒，以及我指定的養育環境，我保證能把其中隨機選出的任何一個訓練成我選定的任何類型的專家——醫生、律師、藝術家、商人，甚至乞丐和小偷，不論他的天賦、愛好、傾向、能力、職業和種族。
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.
