Justice is immortal, eternal, and immutable, like God Himself; and the development of law is only then a progress when it is directed towards those principles which always like Him, are eternal; and whenever prejudice of error succeeds in establishing in customary law any doctrine contrary to eternal justice.

It is, I think, an error to believe that there is any need of religion to make life seem worth living.

The unexamined life, said Socrates, is unfit to be lived by man. This is the virtue of liberty, and the ground on which we may justify our belief in it, that it tolerates error in order to serve truth.

It is one thing to show a man that his is in an error, and another to put him in possession of truth.

Truth is by its very nature intolerant, exclusive, for every truth is the denial of its opposing error.

Nine times out of ten, in the arts as in life, there is actually no truth to be discovered; there is only error to be exposed.

Inquiry is a duty, and error in research is not a sin.

Truth is the kind of error without which a certain species of life could not live. The value of life is ultimately decisive.

It is error only, and not truth, that shrinks from inquiry.

Speak the truth by all means; be bold and fearless in your rebuke of error, and in your keener rebuke of wrong doing; but be human, and loving, and gentle, and brotherly the while.

May those who represent advanced views bear in mind that true wisdom is always joined with mildness, that malice never converts the erring but strengthens him in his attitude, and that it is very unfitting to combat error (so long as this does not assume the aspect of injustice) with the weapons of hatred.

The confirmed prejudices of a thoughtful life, are as hard to change as the confirmed habits of an indolent life: and as some must trifle away age, because they trifled away youth, others must labor on in a maze of error, because they have wandered there too long to find their way out.

Be not ashamed to confess that you have been in the wrong. It is but owning what you need not be ashamed of - that you now have more sense than you had before, to see your error; more humility to acknowledge it, more grace to correct it.

Behold the wretched and dismal slavery of him who is in thrall to pleasures and pains, those utterly capricious and tyrannical master. We, however, must escape to freedom. But this is only possible if we are indifferent to Fortune. Then we shall attain that one overriding blessing - the serenity and exhaltation of a firmly anchored mind. For when error is banished, we shall have the great and satisfying joy that comes from the discovery of truth, plus a kind of disposition and cheerfulness of mind. The source of our pleasure in these things will not derive from their being good, but that they emerge from a good that is one’s own.

There are no mistakes, only lessons. Growth is a process of trail and error: experimentation. The 'failed' experiments are as much a part of the process as the experiment that ultimately 'works.'

Men are apt to prefer a prosperous error to an afflicted truth.

Error is the force that welds men together; truth is communicated to men only by deeds of truth.

The more secure we feel against our liability to any error to which, in fact, we are liable, the greater must be our danger of falling into it.

Every failure is a step to success; every detection of what is false directs us toward what is true; every trial exhausts some tempting form of error. Not only so, but scarcely any attempt is entirely a failure; scarcely any theory, is the result of steady thought, is altogether false; no tempting form of error is without some latent charm derived from truth.

Man is born for action; he ought to do something. Work, at each step, awakens a sleeping force and roots our error. Who does nothing, knows nothing. Rise! to work! If thy knowledge is real, employ it; wrestle with nature; test the strength of thy theories; see if they will support the trial; act!
