I've often said that my rats have taught me much more than I've taught them.

A vast technology has been developed to prevent, reduce, or terminate exhausting labor and physical damage. It is now dedicated to the production of the most trivial conveniences and comfort.

Does a poet create, originate, initiate the thing called a poem, or is his behavior merely the product of his genetic and environmental histories?

We are only just beginning to understand the power of love because we are just beginning to understand the weakness of force and aggression.

I may say that the only differences I expect to see revealed between the behavior of the rat and man (aside from enormous differences of complexity) lie in the field of verbal behavior.

Do not intervene between a person and the consequences of their own behavior.

Unable to understand how or why the person we see behaves as he does, we attribute his behavior to a person we cannot see, whose behavior we cannot explain either but about whom we are not inclined to ask questions.
