The philosophers have only interpreted the world in various ways; the point, however, is to change it.
Karl Marx
Philosophers say a great deal about what is absolutely necessary for science, and it is always, so far as one can see, rather naive, and probably wrong.
Richard Feynman
The natural philosophers are mostly gone. We modern scientists are adding too many decimals
Martin H. Fischer
Various philosophers and religious leaders tried to convince their disciples and followers that animals are nothing more than machines without a soul, without feelings. However, anyone who has ever lived with an animal--be it a dog, a bird, or even a mouse--knows that this theory is a brazen lie, invented to justify cruelty.
Isaac Bashevis Singer
Philosophers and aestheticians may offer elegant and profound definitions of art and beauty, but for the painter they are all summed up in the phrase: To create a harmony.
Gino Severini
Art is an invention of aesthetics, which in turn is an invention of philosophers.... What we call art is a game.
Octavio Paz
Moralists and philosophers have adjudged those who throw temptation in the way of the erring, equally guilty with those who are thereby led into evil
Mark Twain
I do not need the musing of the philosophers to tell me what I am doing. It would be more interesting to let me know why I am doing it.
Louise Bourgeois
The philosopher has never killed any priests, whereas the priest has killed a great many philosophers.
Denis Diderot
Philosophers are only men in armor after all.
Charles Dickens
What sort of philosophers are we, who know absolutely nothing about the origin and destiny of cats?
Henry David Thoreau
Bad philosophers may have a certain influence; good philosophers, never
Bertrand Russell
Many talk like philosophers yet live like fools
Unknown
There is only one thing a philosopher can be relied upon to do, and that is to contradict other philosophers.
William James
I also realized that the philosophers, far from ridding me of my vain doubts, only multiplied the doubts that tormented me and failed to remove any one of them. So I chose another guide and said, Let me follow the Inner Light; it will not lead me so far astray as others have done, or if it does it will be my own fault, and I shall not go so far wrong if I follow my own illusions as if I trusted to their deceits
Jean Jacques Rousseau
