“The three laws of behavioral genetics may be the most important discoveries in the history of psychology. Yet most psychologists have not come to grips with them, and most intellectuals do not understand them …. Here are the three laws:”

—  Steven Pinker , book The Blank Slate

The First Law. All human behavioral traits are heritable.
The Second Law. The effect of being raised in the same family is smaller than the effect of genes.
The Third Law. A substantial portion of the variation in complex human behavioral traits is not accounted for by the effects of genes or families.

“Most effects in psychology are relatively unimportant. That is, most variables, considered in isolation, have relatively little impact on behavior. This doesn't mean… that we should all abandon psychology and become plumbers instead. The small magnitude of most effects in psychology is itself a discovery of psychology. One might argue, in fact, that it is one of the great metadiscoveries of the field. Most variables have little impact, and thus most of the phenomena studied by psychologists are products of a multiplicity of variables.”

“Men do not make laws. They do but discover them. Laws must be justified by something more than the will of the majority. They must rest on the eternal foundation of righteousness. That state is most fortunate in its form of government which has the aptest instruments for the discovery of law.”

“We shall be remembered in history as the most cruel, and therefore the most unwise, generation of men that ever yet troubled the earth: — the most cruel in proportion to their sensibility, — the most unwise in proportion to their science. No people, understanding pain, ever inflicted so much: no people, understanding facts, ever acted on them so little.”

““One of the advantages of having laws is the pleasure one may take in breaking them. We here are not children, Mr. Gurgeh.” Hamin waved the pipestem round the tables of people. “Rules and laws exist only because we take pleasure in doing what they forbid, but as long as most of the people obey such proscriptions most of the time, they have done their job; blind obedience would imply we are—ha!”—Hamin chuckled and pointed at the drone with the pipe—“no more than robots!””
