The scientists often have more unfettered imaginations than current philosophers do. Relativity theory came as a complete surprise to philosophers, and so did quantum mechanics, and so did other things.
Robert Nozick

The tendency of philosophers who know nothing of machinery is to talk of man as a mere mechanism, intending by this to imply that he is without purpose. This shows a lack of understanding of machines as well as of man.
Arthur Young

The tendency to gather and to breed philosophers in universities does not belong to ages of free and humane reflection: it is scholastic and proper to the Middle Ages and to Germany.
George Santayana

The theories of the major philosophers of the 18th century secular enlightenment were biblical and theological in spite of themselves.
M. H. Abrams

The truth has never been of any real value to any human being - it is a symbol for mathematicians and philosophers to pursue. In human relations kindness and lies are worth a thousand truths.
Graham Greene

The world's philosophers and theologians searched for answers to the same mysteries.
Robert Vaughn

The worth of a civilization or a culture is not valued in the terms of its material wealth or military power, but by the quality and achievements of its representative individuals - its philosophers, its poets and its artists.
Herbert Read

Theories of love are found in the works of scientists, philosophers, and theologians.
Mortimer Adler

There is only one thing a philosopher can be relied upon to do, and that is to contradict other philosophers.
William James

There is reason to think the most celebrated philosophers would have been bunglers at business; but the reason is because they despised it.
George Savile

There never was and is not likely soon to be a nation of philosophers, nor am I certain it is desirable that there should be.
Henry David Thoreau

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

These critics organize and practice in my case a sort of obsessive personality cult which philosophers should know how to question and above all, to moderate.
Jacques Derrida

Truth is the object of philosophy, but not always of philosophers.
John Churton Collins

Two half philosophers will probably never a whole metaphysician make.
Gaston Bachelard

We are motivated by a keen desire for praise, and the better a man is the more he is inspired by glory. The very philosophers themselves, even in those books which they write in contempt of glory, inscribe their names.
Marcus Tullius Cicero

We are not to give credit to the many, who say that none ought to be educated but the free; but rather to the philosophers, who say that the well-educated alone are free.
Epictetus

We were promised a society of philosophers. But the Blogosphere is looking more and more like a nation of ankle-biters.
Steven Levy

What every genuine philosopher (every genuine man, in fact) craves most is praise although the philosophers generally call it recognition!
William James

When I look upon seamen, men of science and philosophers, man is the wisest of all beings; when I look upon priests and prophets nothing is as contemptible as man.
Diogenes
