There will be no end to the troubles of states, or of humanity itself, till philosophers become kings in this world, or till those we now call kings and rulers really and truly become philosophers, and political power and philosophy thus come into the same hands
Plato
History is Philosophy teaching by examples.
Thucydides
Philosophy is questions that may never be answered. Religion is answers that may never be questioned
Unknown
What do you know and how do you know it
Ayn Rand
There is but one truly serious philosophical problem, and that is suicide. Judging whether life is or is not worth living amounts to answering the fundamental question of philosophy
Albert Camus
No sooner do we depart from sense and instinct to follow reason but we are insensibly drawn into uncouth paradoxes, difficulties, and inconsistencies, which multiply and grow upon us as we advance in speculation; till at length, having wandered through many intricate mazes, we find ourselves just where we were, or, which is worse, sit down in a forlorn scepticism
George Berkeley
To ridicule philosophy is really to philosophize
Blaise Pascal
Philosophers, for the most part, are constitutionally timid, and dislike the unexpected. Few of them would be genuinely happy as pirates or burglars. Accordingly they invent systems which make the future calculable, at least in its main outlines
Bertrand Russell
I'm a philosophy major. That means I can think deep thoughts about being unemployed
Bruce Lee
In the very books in which philosophers bid us scorn fame, they inscribe their names
Marcus Tullius Cicero
My advice to you is to get married. If you find a good wife you'll be happy; if not you'll become a philosopher
Socrates
Probable impossibilities are to be preferred to improbable possibilities
Aristotle
You cannot go on 'explaining away' for ever: you will find that you have explained explanation itself away. You cannot go on 'seeing through' things for ever. The whole point of seeing through something is to see something through it.
C.S. Lewis
Consciousness is either inexplicable illusion, or else revelation
C.S. Lewis
If we did not bring to the examinations of our instincts a knowledge of their comparative dignity we could never learn it from them
C.S. Lewis
