For knowing is spoken of in three ways: it may be either universal knowledge or knowledge proper to the matter in hand or actualising such knowledge; consequently three kinds of error also are possible.
There is no more evil thing in this world than race prejudice, none at all. [...] It justifies and holds together more baseness, cruelty, and abomination than any other sort of error in the world.
The evils of the body are murder, theft, and adultery; of the tongue, lying, slander, abuse and idle talk; of the mind, covetousness, hatred and error.
The near side of a galaxy is tens of thousands of light-years closer to us than the far side; thus we see the front as it was tens of thousands of years before the back. But typical events in galactic dynamics occupy tens of millions of years, so the error in thinking of an image of a galaxy as frozen in one moment of time is small.
In a bull market, one must avoid the error of the preening duck that quacks boastfully after a torrential rainstorm, thinking that its paddling skills have caused it to rise in the world. A right-thinking duck would instead compare its position after the downpour to that of the other ducks on the pond.
What is this self-inside us, this silent observer, severe and speechless critic, who can terrorize us, and urge us onto futile activity, and in the end, judge us still more severely for the errors into which his own reproaches drove us?
Not complete inaction, which is an error, a confusion, a self-delusion, an impossibility, but action full and
free done without subjection to sense and passion, desireless and unattached works, are the first secret of perfection.
A wild angel had appeared to him, the angel of mortal youth and beauty, an envoy from the fair courts of life, to throw open before him in an instant of ecstasy the gates of all the ways of error and glory.
Indeed the reasoned criticism of a prevailing belief is a service to the proponents of that belief; if they are incapable of defending it, they are well advised to abandon it. This self-questioning and error-correcting aspect of the scientific method is its most striking property.
Another error is an impatience of doubt and haste to assertion without due and mature suspension of judgment. For the two ways of contemplation are not unlike the two ways of action commonly spoken of by the ancients; the one plain and smooth in the beginning, and in the end impassable; the other rough and troublesome in the entrance, but after a while fair and even. So it is in contemplation; if a man will begin with certainties, he shall end in doubts; but if he will be content to begin with doubts, he shall end in certainties.
If I err in belief that the souls of men are immortal, I gladly err, nor do I wish this error which gives me pleasure to be wrested from me while I live.
After long study and experience, I have come to the conclusion that (1) all religions are true; (2) all religions have some error in them; (3) all religions are almost as dear to me as my own Hinduism, in as much as all human beings should be as dear to one as one's own close relatives.
Understand that for every rule which I have mentioned from the Quran, the Devil has one to match it, which he puts beside the proper rule to cause error.
The mind moves by instincts, associations and premonitions and not by fixed dates or completed processes. Action and reaction will occur simultaneously: or the cause actually be found after the effect. Errors will be resisted before they have been properly promulgated: notions will be first defined long after they are dead.
