One might think this means that imaginary numbers are just a mathematical game having nothing to do with the real world. From the viewpoint of positivist philosophy, however, one cannot determine what is real. All one can do is find which mathematical models describe the universe we live in. It turns out that a mathematical model involving imaginary time predicts not only effects we have already observed but also effects we have not been able to measure yet nevertheless believe in for other reasons. So what is real and what is imaginary? Is the distinction just in our minds?

Stephen Hawking

If you condemn painting, which is the only imitator of all visible works of nature, you will certainly despise a subtle invention which brings philosophy and subtle speculation to the consideration of the nature of all forms — seas and plains, trees, animals, plants and flowers — which are surrounded by shade and light. And this is true knowledge and the legitimate issue of nature; for painting is born of nature — or, to speak more correctly, we will say it is the grandchild of nature; for all visible things are produced by nature, and these her children have given birth to painting. Hence we may justly call it the grandchild of nature and related to God.

Leonardo da Vinci

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. All the rest — whether or not the world has three dimensions, whether the mind has nine or twelve categories — comes afterward. These are games; one must first answer.

Philosophy stands in the same relation to the study of the actual world as masturbation to sexual love.

The philosopher's conception of things will, above all, be truer than other men's, and his philosophy will subordinate all the circumstances of life. To live like a philosopher is to live, not foolishly, like other men, but wisely and according to universal laws.

Henry David Thoreau

Philosophy, when superficially studied, excites doubt; when thoroughly explored, it dispels it.

We account the Scriptures of God to be the most sublime philosophy. I find more sure remarks of authenticity in the Bible than in any profane history whatever.

If what we regard as real depends on our theory, how can we make reality the basis of our philosophy?...But we cannot distinguish what is real about the universe without a theory...it makes no sense to ask if it corresponds to reality, because we do not know what reality is independent of a theory.

Stephen Hawking

If it is a question of seeking formal contradictions, then obviously we must do so on the side of the White Terror, which is the weapon of classes which consider themselves Christian, patronize idealist philosophy, and are firmly convinced that the individuality (their own) is an end-in-itself. As for us, we were never concerned with the Kantian-priestly and vegetarian-Quaker prattle about the sacredness of human life. We were revolutionaries in opposition, and have remained revolutionaries in power. To make the individual sacred we must destroy the social order which crucifies him. And this problem can only be solved by blood and iron.

A philosophy does not play its role as an actor during a recital; it interacts with other philosophies and with other facts, and it cannot know the results of the interaction between itself and other world visions.

Our age is retrospective. It builds the sepulchres of the fathers. It writes biographies, histories, and criticism. The foregoing generation beheld God and nature face to face; we, through their eyes. Why should not we also enjoy an original relation to the universe. Why should not we have a poetry and philosophy of insight and not of tradition, and a religion by revelation to us, and not the history of theirs?

Ralph Waldo Emerson

Society triumphs over many. They wish to regenerate the world with their institutions, with their moral philosophy, with their love. Then they sink to living from breakfast till dinner, from dinner till tea, with a little worsted work, and to looking forward to nothing but bed.
When shall we see a life full of steady enthusiasm, walking straight to its aim, flying home, as that bird is now, against the wind — with the calmness and the confidence of one who knows the laws of God and can apply them?

Florence Nightingale

The ductless glands secrete among other things our moods, our aspirations, our philosophy of life.

Philosophy directs us first to seek the goods of the mind, and the rest will either be supplied, or are not much wanted.

In philosophy at the universities truth occupies only a secondary place and, if called upon, she must get up and make room for another attribute.

Arthur Schopenhauer

Philosophy is certainly the medicine of the soul. Its aid is to be sought not from without, as in diseases of the body; and we must labour with all our resources and with all our strength to cure ourselves.

The man who has no tincture of philosophy goes through life imprisoned in the prejudices derived from common sense, from the habitual beliefs of his age or his nation, and from convictions which have grown up in his mind without the cooperation or consent of his deliberate reason.

Bertrand Russell

The Scripture was written to shew unto men the kingdom of God; and to prepare their minds to become his obedient subjects; leavingthe world, and the Philosophy thereof, to the disputation of men, for the exercising of their natural Reason.

My philosophy is that if I have any money I invest it in new ventures and not have it sitting around.

Richard Branson

Philosophy … bears witness to the deepest love of reflection, to absolute delight in wisdom.

To learn is not to know; there are the learners and the learned. Memory makes the one, philosophy the other.

Alexandre Dumas

Life does not agree with philosophy: There is no happiness that is not idleness, and only what is useless is pleasurable.

From the very beginning, existentialism defined itself as a philosophy of ambiguity.

Simone de Beauvoir

Philosophy leaps ahead on tiny toeholds; hope and intuition lend wings to its feet. Calculating reason lumbers heavily behind, looking for better footholds, for reason too wants to reach that alluring goal which its divine comrade has long since reached.

Friedrich Nietzsche

For this feeling of wonder shows that you are a philosopher, since wonder is the only beginning of philosophy.
