Echoes

Truth is the daughter of time, not of authority.

It is not truth that makes man great, but man that makes truth great.

Do not go by revelation; Do not go by tradition; Do not go by hearsay; Do not go on the authority of sacred texts; Do not go on the grounds of pure logic; Do not go by a view that seems rational; Do not go by reflecting on mere appearances; Do not go along with a considered view because you agree with it; Do not go along on the grounds that the person is competent; Do not go along because "the recluse is our teacher." Kalamas, when you yourselves know: These things are unwholesome, these things are blameworthy; these things are censured by the wise; and when undertaken and observed, these things lead to harm and ill, abandon them... Kalamas, when you know for yourselves: These are wholesome; these things are not blameworthy; these things are praised by the wise; undertaken and observed, these things lead to benefit and happiness, having undertaken them, abide in them.

You are neither right nor wrong because people agree with you.

A very great deal more truth can become known than can be proven.

I believe that the extraordinary should certainly be pursued. But extraordinary claims require extraordinary evidence.

He needs no library, for he has not done thinking; no church, for he is himself a prophet; no statute book, for he hath the Lawgiver; no money, for he is value itself; no road, for he is at home where he is.

I know that I know nothing.

All formal dogmatic religions are fallacious and must never be accepted by self-respecting persons as final.

The way to find out about our place in the universe is by examining the universe and by examining ourselves—without preconceptions, with as unbiased a mind as we can muster. We cannot begin with an entirely clean slate, since we arrive at this problem with predispositions of hereditary and environmental origin; but, after understanding such built-in biases, is it not possible to pry insights from nature?

My Son, beware thou dispute not of high matters and of the hidden judgments of God; why this man is thus left, and that man is taken into so great favour; why also this man is so greatly afflicted, and that so highly exalted. These things pass all man’s power of judging, neither may any reasoning or disputation have power to search out the divine judgments. When therefore the enemy suggesteth these things to thee, or when any curious people ask such questions, answer with that word of the Prophet, Just art Thou, O Lord, and true is Thy judgment, and with this, The judgments of the Lord are true, and righteous altogether. My judgments are to be feared, not to be disputed on, because they are incomprehensible to human understanding.

Reserve your right to think, for even to think wrongly is better than not to think at all.

Learn about pines from the pine, and about bamboo from the bamboo.

There is more wisdom in your body than in your deepest philosophy.

Let us not underrate the value of a fact; it will one day flower in a truth.

All our scientific and philosophic ideals are altars to unknown gods.

Science is a differential equation. Religion is a boundary condition.

Truth is sought not because it is truth but because it is good.

There is only one good, knowledge, and one evil, ignorance.

Without courage, wisdom bears no fruit.

Men are at variance with the one thing with which they are in the most unbroken communion, the reason that administers the whole universe.

All men by nature desire to know. An indication of this is the delight we take in our senses; for even apart from their usefulness they are loved for themselves; and above all others the sense of sight. For not only with a view to action, but even when we are not going to do anything, we prefer sight to almost everything else. The reason is that this, most of all the senses, makes us know and brings to light many differences between things.

Nature never deceives us; it is we who deceive ourselves.

I cannot sufficiently admire the eminence of those men's wits, that have received and held it to be true, and with the sprightliness of their judgments offered such violence to their own senses, as that they have been able to prefer that which their reason dictated to them, to that which sensible experiments represented most manifestly to the contrary. ...I cannot find any bounds for my admiration, how that reason was able in Aristarchus and Copernicus, to commit such a rape on their senses, as in despite thereof to make herself mistress of their credulity.

Come forth into the light of things, let Nature be your teacher.
