In the world of today can there be peace anywhere until there is peace everywhere?

Generals are usually a conservative force who can be relied on to oppose social change.

Often, writers on historical events tend to consider ... a loss of willingness to fight as a sign of "decadence," as though there were something despicable about not being a bully and not being willing to engage in mass murder. Perhaps we ought to feel instead that to cease to be warlike means to begin to be civilized and decent.

476 ... is usually taken as the date of the "fall of the Roman Empire." The date, however, is a false one. No one at this period of time considered that the Roman Empire had "fallen." Indeed, it still existed and was the most powerful realm in Europe. Its capital was at Constantinople and the Emperor was Zeno. It is only because we ourselves are culturally descended from the Roman west, that we tend to ignore the continued existence of the Roman Empire in the east.

It is an odd fact that anyone who wishes to start a war must always make it appear that he is fighting in a just cause even if the real motive is naked aggression. Fortunately for the would-be aggressor, a "just cause" is very easy to find.

Probably, the most-often-repeated lesson in history is that foreigners who are called in to help one side in a civil war take over for themselves. It is a lesson that seems never to be learned despite endless repetition.

For man to become successful, for man to establish himself as the ruler of the planet, it was necessary for him to use his brain as something more than a device to make the daily routine of getting food and evading enemies a little more efficient. Man had to learn to control his environment.

Inspect every piece of pseudoscience and you will find a security blanket, a thumb to suck, a skirt to hold. What does the scientist have to offer in exchange? Uncertainty! Insecurity!

I recognize the necessity of animal experiments with my mind but not with my heart.

I consider one of the most important duties of any scientist the teaching of science to students and to the general public.
