A democracy which makes or even effectively prepares for modern, scientific war must necessarily cease to be democratic. No country can be really well prepared for modern war unless it is governed by a tyrant, at the head of a highly trained and perfectly obedient bureaucracy. Aldous Huxley
A lot of the reasons why something is a favorite thing are all things you don't necessarily see, the place, the people, the time, where you are, what it meant to you at the time. Jeffrey Jones
A raised weight can produce work, but in doing so it must necessarily sink from its height, and, when it has fallen as deep as it can fall, its gravity remains as before, but it can no longer do work. Hermann von Helmholtz
A successful person isn't necessarily better than her less successful peers at solving problems; her pattern-recognition facilities have just learned what problems are worth solving. Ray Kurzweil
A toothache, or a violent passion, is not necessarily diminished by our knowledge of its causes, its character, its importance or insignificance. T. S. Eliot
Ages when custom is unsettled are necessarily ages of prophecy. The moralist cannot teach what is revealed; he must reveal what can be taught. He has to seek insight rather than to preach. Walter Lippmann
Although it has been said by men of more wit than wisdom, and perhaps more malice than either, that women are naturally incapable of acting prudently, or that they are necessarily determined to folly, I must by no means grant it.
