The man in charge must concern himself with details. If he does not consider them important, neither will his subordinates.

The devil is in the details, and everything we do in the military is a detail.

Success teaches us nothing; only failure teaches.

How the hell are you supposed to know what God wants you to do with your life, eh?

To doubt one's own first principles is the mark of a civilized man. Don't defend past actions; what is right today may be wrong tomorrow. Don't be consistent; consistency is the refuge of fools.

In Greek mythology, Antaeus was a giant who was strong as long as he had contact with the earth. When he was lifted from the earth he lost strength. So it is with engineers. They must not become isolated from the real world...

As a guide to engineering ethics, I should like to commend to you a liberal adaptation of the injunction contained in the oath of Hippocrates that the professional man do nothing that will harm his client.
