“Because intelligent choices of public policies require both technical understanding and sensitivity to the values involved, in modern democratic countries a form of specialized intellectual activity has evolved that tends to combine both aspects of policy.”

Academy of Achievement interview (1991)
Context: Reason alone will not serve. Intuition alone can be improved by reason, but reason alone without intuition can easily lead the wrong way. They both are necessary. The way I like to put it is that when I have an intuition about something, I send it over to the reason department. Then after I've checked it out in the reason department, I send it back to the intuition department to make sure that it's still all right. That's how my mind works, and that's how I work. That's why I think that there is both an art and a science to what we do. The art of science is as important as so-called technical science. You need both. It's this combination that must be recognized and acknowledged and valued.

Context: Already a considerable sum is appropriated to give the negroes vocational training in agriculture. About half a million dollars is recommended for medical courses at Howard University to help contribute to the education of 500 colored doctors needed each year. On account of the integration of large numbers into industrial centers, it has been proposed that a commission be created, composed of members from both races, to formulate a better policy for mutual understanding and confidence. Such an effort is to be commended. Everyone would rejoice in the accomplishment of the results which it seeks. But it is well to recognize that these difficulties are to a large extent local problems which must be worked out by the mutual forbearance and human kindness of each community. Such a method gives much more promise of a real remedy than outside interference.
