“Where is the Life we have lost in living? Where is the wisdom we have lost in knowledge? Where is the knowledge we have lost in information?”

If you don’t know where you are going, every road will get you nowhere.

Don’t be too ambitious. Do the most important thing you can think of doing every year and then your career will take care of itself.

Covert action should not be confused with missionary work.

For nations, history plays the role that character confers on human beings.

A more immediate issue concerns North Korea, to which Bismarck’s nineteenth-century aphorism surely applies: We live in a wondrous time, in which the strong is weak because of his scruples and the weak grows strong because of his audacity.

Knowledge isn’t power until it is applied.
