The [engineer] should be equipped with knowledge of many branches of study and varied kinds of learning, for it is by his judgement that all work done by the other arts is put to test. This knowledge is the child of practice and theory.
Vitruvius

Torture is an impermissible evil. Except under two circumstances. The first is the ticking time bomb. An innocent's life is at stake. The bad guy you have captured possesses information that could save this life. He refuses to divulge. In such a case, the choice is easy.
Charles Krauthammer
