B. F. Skinner

Better contraceptives will control population only if people will use them. A nuclear holocaust can be prevented only if the conditions under which nations make war can be changed. The environment will continue to deteriorate until pollution practices are abandoned. We need to make vast changes in human behavior.

Education is what survives when what has been learned has been forgotten.

We are all controlled by the world in which we live.... The question is this: are we to be controlled by accidents, by tyrants, or by ourselves?
