Sit down before fact with an open mind. Be prepared to give up every preconceived notion. Follow humbly wherever and to whatever abyss Nature leads, … - Hyman G. Rickover

If history has any meaning for us, it shows that men will continue to use the best weapons they have to win. Throughout history, even when men have established leagues to prevent war, they have nevertheless resorted to it. Utopia is still beyond the horizon. Above all, we should bear in mind that our liberty is not an end in itself; it is a means to win respect for human dignity for all classes of our society.

I am not proud of the part I played in it. I did it because it was necessary for the safety of this country. That's why I am such a great exponent of stopping this whole nonsense of war. Unfortunately limits — attempts to limit war have always failed. The lesson of history is when a war starts every nation will ultimately use whatever weapon it has available. ... Therefore, we must expect that if another war — a serious war — breaks out, we will use nuclear energy in some form.

Life is not meaningless for the man who considers certain actions wrong simply because they are wrong, whether or not they violate the law. This kind of moral code gives a person a focus, a basis on which to conduct himself. Certainly there is a temptation to let go of morals in order to do the expedient thing. But there is also a tremendous power in standing by what is right. Principle and accomplishment need not be incompatible. A common thread moves through all the principles I have discussed: It is the desire to improve oneself and one's surroundings by actively participating in life. Too many succumb to the emotional preference of the comfortable solution instead of the difficult one. It is easy to do nothing. And to do nothing is also an act; an act of indifference or cowardice. A person must prepare himself intellectually and professionally and then use his powers to their fullest extent.
