Experience is the oracle of truth; and where its responses are unequivocal, they ought to be conclusive and sacred.

Expirience is the oracle of truth

Experience is, for me, the highest authority. The touchstone of validity is my own experience. No other person's ideas, and none of my own ideas, are as authoritative as my experience. It is to experience that I must return again and again, to discover a closer approximation to truth as it is in the process of becoming in me. Neither the Bible nor the prophets -- neither Freud nor research -- neither the revelations of God nor man -- can take precedence over my own direct experience. My experience is not authoritative because it is infallible. It is the basis of authority because it can always be checked in new primary ways. In this way its frequent error or fallibility is always open to correction.

Wisdom is the echo of experience.

Experience is a truer guide than the words of others.

Experience to be experience must be reality; truth to be true must be true of reality. Experience, truth and reality are inseparable.

Experience is the only source of wisdom: by which I mean, the competent conduct of life.

Truth is what stands the test of experience.

Experiment is the sole source of truth. It alone can teach us something new; it alone can give us certainty.

Experience is the only prophecy of wise men.

By far the best proof is experience.

"Experience is the thing of supreme value".

The highest, most decisive experience is to be alone with one's own self. You must be alone to find out what supports you, when you find that you can not support yourself. Only this experience can give you an indestructible foundation.

Inner experience, unable to have principles either in dogma (a moral attitude), or in science (knowledge can be neither its goal nor its origin), or in a search of enriching states (an experimental, aesthetic attitude), it cannot have any other concern nor other goal than itself. Opening myself to inner experience, I have placed in it all value and authority. Henceforth I can have no other value, no other authority (in the realm of mind). Value and authority imply the discipline of a method, the existence of a community.
I call experience a voyage to the end of the possible of man. Anyone may choose not to embark on this voyage, but if he does embark on it, this supposes the negation of the authorities, the existing values which limit the possible. By virtue of the fact that it is negation of other values, other authorities, experience, having a positive existence, becomes itself positively value and authority.
Inner experience has always had objectives other than itself in which one invested value and authority. … If God, knowledge, and suppression of pain were to cease to be in my eyes convincing objectives, … would inner experience from that moment seem empty to me, henceforth impossible without justification? ...
I received the answer [from Blanchot]: experience itself is authority.
