The profoundest thoughts of the philosophers have something trickle about them. A lot disappears in order for something to suddenly appear in the palm of the hand.
Actual philosophers... are commanders and law-givers: they say "thus it shall be!", it is they who determine the Wherefore and Whither of mankind, and they possess for this task the preliminary work of all the philosophical laborers, of all those who have subdued the past - they reach for the future with creative hand, and everything that is or has been becomes for them a means, an instrument, a hammer.
No philosophical theory which I have yet come across is a radical improvement on the words of Genesis, that 'In the beginning God made Heaven and Earth'.
..when, in my philosophical disquisitions, I deny a providence and a future state, I undermine not the foundations of society, but advance principles, which they themselves, upon their own topics, if they argue consistently, must allow to be solid and satisfactory.
Science is a human activity, and the best way to understand it is to understand the individual human beings who practise it. Science is an art form and not a philosophical method. The great advances in science usually result from new tools rather than from new doctrines. ... Every time we introduce a new tool, it always leads to new and unexpected discoveries, because Nature's imagination is richer than ours.
'Thou shalt not kill' does not apply to murder of one's own kind only, but to all living beings and this commandment was inscribed in the human breast long before it was proclaimed from Sinai.
In a disordered mind, as in a disordered body, soundness of health is impossible.
The study of the human brain and its disease remains one of the greatest scientific and philosophical challenges ever undertaken.
Buddhism is a hundred times as realistic as Christianity it is part of its living heritage that it is able to face problems objectively and coolly; it is the product of long centuries of philosophical speculation.
The sense that the meaning of the universe had evaporated was what seemed to escape those who welcomed Darwin as a benefactor of mankind. Nietzsche considered that evolution presented a correct picture of the world, but that it was a disastrous picture. His philosophy was an attempt to produce a new world-picture which took Darwinism into account but was not nullified by it.
In my opinion a mathematician, in so far as he is a mathematician, need not preoccupy himself with philosophy-an opinion, moreover, which has been expressed by many philosophers.
Indiana Jones: Archaeology is the search for fact... not truth. If it's truth you're looking for, Dr. Tyree's philosophy class is right down the hall. ... So forget any ideas you've got about lost cities, exotic travel, and digging up the world. We do not follow maps to buried treasure, and "X" never, ever marks the spot. Seventy percent of all archaeology is done in the library. Research. Reading.
The traditional disputes of philosophers are, for the most part, as unwarranted as they are unfruitful. The surest way to end them is to establish beyond question what should be the purpose and method of a philosophical enquiry. And this is by no means so difficult a task as the history of philosophy would lead one to suppose. For if there are any questions which science leaves it to philosophy to answer, a straightforward process of elimination must lead to their discovery.
