Curiosity is the lust of the mind.
I am not ashamed to admit that I belong to those who fantasize that literature is capable of bringing new horizons and new perspectives--philosophical, religious, aesthetical and even social.
I have presented principles of philosophy that are not, however, philosophical but strictly mathematical-that is, those on which the study of philosophy can be based. These principles are the laws and conditions of motions and of forces, which especially relate to philosophy.
We come to recognize that playfulness, as a philosophical stance, can be very serious indeed; and moreover, that it possesses an unfailing capacity to arouse ridicule and hostility in those among us who crave certainty, reverence, and restraint.
The absolute things, the last things, the overlapping things, are the truly philosophic concerns; all superior minds feel seriously about them, and the mind with the shortest views is simply the mind of the more shallow man.
It seems to me obvious that infants and many animals that do not in any ordinary sense have a language or perform speech acts nonetheless have Intentional states. Only someone in the grip of a philosophical theory would deny that small babies can literally be said to want milk and that dogs want to be let out or believe that their master is at the door.
The conduct of a man, who studies philosophy in this careless manner, is more truly sceptical than that of any one, who feeling inhimself an inclination to it, is yet so over-whelm'd with doubts and scruples, as totally to reject it. A true sceptic will be diffident of his philosophical doubts, as well as of his philosophical conviction; and will never refuse any innocent satisfaction, which offers itself, upon account of either of them.
The display of grief makes more demands than grief itself. How few men are sad in their own company.
Oh, Heaven, it is mysterious, it is awful to consider that we not only carry a future Ghost within us; but are, in very deed, Ghosts!
Humility is the most difficult of all virtues to achieve; nothing dies harder than the desire to think well of self.
