Washington Irving on American public mind

Governed, as we are, entirely by public opinion, the utmost care should be taken to preserve the purity of the public mind. Knowledge is power, and truth is knowledge; whoever, therefore, knowingly propagates a prejudice, willfully saps the foundation of his country’s strength.

 

Washington Irving, The Sketch-Book of Geoffrey Crayon

Blake: From The Marriage of Heaven and Hell

No bird soars too high if he soars with his own wings.

The fox condemns the trap, not himself.

What is now proved was once only imagined.

Everything possible to be believed is an image of truth.

Expect poison from the standing water.

You never know what is enough unless you know what is more than enough.

To create a little flower is the labor of ages.

If the doors of perception were cleansed everything would appear to man as it is, infinite. 

 

William Blake, The Marriage of Heaven and Hell

The births of all things are weak and tender; and therefore we should have our eyes intent on beginnings; for as when, in its infancy, the danger is not perceived, so when it is grown up, the remedy is as little to be found.

'Tis a misfortune to be at such a pass, that the best test of truth is the multitude of believers in a crowd, where the number of fools so much exceeds the wise.

Montaigne

The opposite of a correct statement is a false statement. But the opposite of a profound truth may well be another profound truth.

Niels Bohr

These are the times we live in, in which men hide their truths, perhaps even from themselves, and live in lies, until the lies reveal those truths in ways impossible to foretell.

Salman Rushdie, The Golden House

Often, the surest way to convey misinformation is to tell the strict truth.

Mark Twain, Following the Equator: A Journey Around the World 

The entitlement to believe what on careful reflection seems to be the case, where there is no reason to doubt it, is the necessary condition for being able to form any justified beliefs at all. ... The only way to pursue the truth is to consider what seems true, after careful reflection of a kind appropriate to the subject matter, in light of all the relevant data, principles, and circumstances.


Thomas Nagel, Listening to Reason (New York Review, October 9, 2014)

Truth is one.  The wise speak of it in many ways.

Rig Veda

I want to be an idiot and tell the king good and proper that his country is rubbish.

László Krasznahorkai, The Melancholy of Resistance
