Search for Knowledge
Guard against the prestige of great names; see that your judgments are your own; and do not shrink from disagreement; no trusting without testing.
-John Dalberg, Lord Acton
*The acceptance of a fact as a fact is the starting point, and if this is sufficiently clear, there will be no further need to ask why it is so. A man with this kind of background has or can easily acquire the foundations from which he must start. But if he neither has nor can acquire them, let him lend an ear to Hesiod's words:
             The man is all-best who himself works out every problem. . . .
             That man, too, is admirable who follows one who speaks well.
             He who cannot see the truth for himself, nor, hearing it from others,
             Store it away in his mind, that man is utterly useless.
(archê gar to hoti, kai ei touto phainoito arkountôs, ouden prosdeêsei tou dioti: ho de toioutos echei ê laboi an archas rhaidiôs. hôi de mêdeteron huparchei toutôn, akousatô tôn Hêsiodou:
             houtos men panaristos hos autos panta noêsêi, esthlos d' au

It will contribute towards one's object, who wishes to acquire a facility in the gaining of knowledge, to doubt judiciously.
-Aristotle
Truth arises more readily from error than from confusion.
-Francis Bacon
*Some Pharisees who were with him heard him say this and asked, "What? Are we blind too?"
Jesus said, "If you were blind, you would not be guilty of sin; but now that you claim you can see, your guilt remains.

The Devil's Dictionary, 1906
I am one of the people who love the why of things.
-Catherine II of Russia
Men occasionally stumble on the truth, but most of them pick themselves up and hurry off as if nothing had happened.
-Winston Churchill
It is a shameful thing to be weary of inquiry when what we search for is excellent.
-Marcus Tullius Cicero
*Philosophy is like waking up in a strange, dark room. At first, you question your thoughts and attempt to gain a sense of yourself and your situation. You don't know where you are, and sometimes, even how you got there. As you search, you begin to discover your surroundings. Occasionally, you may touch upon an object that you can identify immediately. But more often, you must feel around it, listen to it, and test it, before you can decide what it is and its usefulness to you. Once in a while though, you will discover a tool, a lamp, for instance, and once you discover its meaning and use, this tool will allow you to see more clearly the other objects in the room. As you discover more about your environment, you build upon the objects you've uncovered. Your knowledge and awareness grow at ever faster rates until, ultimately, you grasp the meaning of the room. Then what do you do? You leave it. But you have not really left the room at all. You have only made it bigger.
-Michael Conover
In seeking truth you have to get both sides of the story.
-Walter Kronkite
False views. . .do very little harm, for everyone takes a salutary pleasure in proving their falseness; and when this is done, one path towards error is closed and the road to truth is often at the same time opened.
-Charles Darwin
If you would be a real seeker after truth, it is necessary that at least once in your life you doubt, as far as possible, all things.
-Rene Descartes
. . . the conviction persists - though history has shown it to be a hallucination - that all the questions that the human mind has asked are questions that can be answered in terms of the alternatives that the questions themselves present. But in fact intellectual progress usually occurs through sheer abandonment of questions together with both of the alternatives they assume - an abandonment that results from their decreasing vitality and change of urgent interest. We do not solve them: we get over them. Old questions are solved by disappearing, evaporating, while new questions corresponding to the changed attitude of endeavor and preference take their place.
-John Dewey
Take nothing on its looks: take everything on evidence. There's no better rule.
-Charles Dickens
The fool wonders, the wise man asks.
-Benjamin Disraeli
When you have excluded the impossible, whatever remains, however improbable, must be the truth.
-Arthur Conan Doyle
The important thing is to not stop questioning.
-Albert Einstein
The search for truth is more precious than its possession.
-Albert Einstein
The factual correction of error may be the most sublime event in intellectual life, the ultimate sign of our necessary obedience to a larger reality and our inability to construct the world according to our desires. For science, in particular, factual correction holds a specially revered place for two reasons: first, because we define the enterprise as learning more and more about an external reality; second, because we know in our hearts that we can be as stubborn and resistant to change as petty bureaucrats and fundamentalist preachers--and undeniable factual correction therefore becomes a kind of salvation from our own emotional transgressions against a shared ideal.
-Stephen Jay Gould
Doubt 'til thou canst doubt no more. . . doubt is thought, and thought is life. Systems which end doubt are devices for drugging thought.
-Albert Guerard
Seek the company of those who were looking for the truth, but run from those who have found it.
-Vaclav Havel
Sit down before every fact as a little child, be prepared to give up every preconceived notion, follow humbly wherever and to whatever abyss nature leads, or you shall learn nothing.
-Thomas Henry Huxley
We have to live today by what truth we can get today and be ready tomorrow to call it falsehood.
-William James
I keep six honest serving men
   (They taught me all I knew);
Their names were What and Why and When
   and How and Where and Who.
-Rudyard Kipling
"I Keep Six Honest. . ."
*When truths are once known to us, though by tradition, we are apt to be favorable to our own parts and ascribe to our own understandings the discovery of what, in reality, we borrowed from others-or, at least, finding we can prove what at first we learn from others, we are forward to conclude it an obvious truth, which, if we had sought, we could not have missed. Nothing seems hard to our understandings that is once known; and because what we see, we see with our own eyes, we are apt to overlook or forget the help we had from others who showed it us and first made us see it, as if we were not at all beholden to them for those truths they opened the way to and led us into. For knowledge being only of truths that are perceived to be so, we are favorable enough to our own faculties to conclude, that they of their own strength would have attained those discoveries, without any foreign assistance, and that we know those truths by the strength and native light of our own minds, as they did from whom we received them by theirs, only they had the luck to be before us. Thus the whole stock of human knowledge is claimed by everyone as his private possession, as soon as he (profiting by other's discoveries) has got it into this own mind-and so it is-but not properly by his own single industry nor of his own acquisition.
-John Locke
The Reasonableness of Christianity as Delivered in the Scriptures, 1695
One of the greatest joys known to man is to take a flight into ignorance in search of knowledge.
-Robert Lynd
Always question. Always analyze. But in the end, suspend judgement until you've been there. Live it to learn it.
-Mark McClinchie
I respect faith but doubt is what gets you an education.

The road to truth is long, and lined the entire way with annoying bastards.

The Place of No Shadows
To be surprised, to wonder, is to begin to understand.
-Jose Ortega y Gasset
Contradiction is not the sign of falsity, nor the lack of contradiction a sign of truth.
-Blaise Pascal
*Is it not rather the case that the man who prepares himself most carefully to apprehend by his intellect the essence of each thing which he examines will come nearest to the knowledge of it?
-The character Socrates, in Plato's Phaedo
65e
Not to know is bad, not to wish to know is worse.
-Nigerian proverb
*A man who is honestly convinced that he can find no answers, would not feel the need to pretend that he is looking for them.
-Ayn Rand
Philosophy: Who Needs It?, 1982
"Faith and Force: The Destroyers of the Modern World", 1960
Leonard Peikoff, ed.
I have come to the conclusion that a person should never accept any statement or even fact as being the absolute truth . . .No statement should be believed merely because it has been made by an authority.
-Hans Reichenbach
If error is corrected whenever it is recognized as such, the path of error is the path of truth.
-Hans Reichenbach
*We make our world significant by the courage of our questions and by the depth of our answers.
-Carl Sagan
Cosmos, 1980
Chapter VII, "The Backbone of the Night"
At the heart of science is an essential tension between two seemingly contradictory attitudes--an openness to new ideas, no matter how bizarre or counterintuitive they may be, and the most ruthless skeptical scrutiny of all ideas, old and new. This is how deep truths are winnowed from deep nonsense. Of course, scientists make mistakes in trying to understand the world, but there is a built-in error- correcting mechanism: The collective enterprise of creative thinking and skeptical thinking together keeps the field on track.
-Carl Sagan
~[M]odest doubt is call'd the beacon of the wise.
-Hector, a character in William Shakespeare's The History of Troilus and Cressida, 1602
Act 2, scene ii
The first step to knowledge is to know that we are ignorant.
-Socrates
There is a principle which is a bar against all information, which is proof against all arguments and which cannot fail to keep a man in everlasting ignorance -- that principle is contempt prior to investigation.
-Herbert Spencer
The authoritarian sets up some book, or man, or tradition to establish the truth. The freethinker sets up reason and private judgement to discover the truth.
-Herbert Spencer
Freedom and Its Foundations
I know that most men, including those at ease with problems of the greatest complexity, can seldom accept even the simplest and most obvious truth if it be such as would oblige them to admit the falsity of conclusions which they have delighted in explaining to colleagues, which they have proudly taught to others, and which they have woven, thread by thread, into the fabric of their lives.
-Leo Tolstoy
One who presumes to know the truth stops looking for it.
-Unknown
Observation, and not old age, brings wisdom.
-Unknown
Any progress in knowledge, any worthwhile achievement, depends on our attempts to transcend one particular viewpoint and develop an expanded consciousness that takes in the world more fully.
-Unknown
*[H]omo sapiens is human in the full sense of the word only when his grammar is entirely free of question marks, when it has nothing but exclamation points, periods, and commas.
- D-503, the hero in Yevgeny Zamyatin's We, 1920-1921
