Politics is mostly non-rational; the world is suffering from some kind of mental disorder which must be diagnosed before it can be cured.

More quotes by Orwell, George

We must not suppose that, because a man is a rational animal, he will, therefore, always act rationally; or, because he has such or such a predominant passion, that he will act invariably and consequentially in the pursuit of it. No, we are complicated machines; and though we have one main spring that gives motion to the whole, we have an infinity of little wheels, which, in their turns, retard, precipitate, and sometimes stop that motion.

The danger of religious faith is that it allows otherwise normal human beings to reap the fruits of madness and consider them holy.

I can calculate the movement of the stars, but not the madness of the people.

Isaac Newton (1642-1727) English physicist and mathematician
(Attributed)

Supposedly after the ruinous stock price collapse of the "South Sea Bubble" in 1720, in which Newton lost £20,000.

The earliest mention of this is found in Joseph Spence, Second Memorandum Book (1756), collected in Joseph Spence (ed. Samuel Weller Singer), Anecdotes, Observations, and Characters, of Books and Men (1820). There a Lord Radnor is quoted as saying: "When Sir Isaac Newton was asked about the continuance of the rising of South Sea stock? — He answered, 'that he could not calculate the madness of the people.'" (Note that this supposedly takes place before the bubble bursts.)

Variants:
  • I can calculate the motions of erratic bodies, but not the madness of a multitude. ["Mammon and the Money Market," The Church of England Quarterly Review (1850)]
  • I can calculate the motions of the heavenly bodies, but not the madness of people.
  • I can calculate the motions of heavenly bodies but not the madness of men.
  • I can calculate the movement of stars, but not the madness of men.

More quotes by Newton, Isaac

There are two kinds of fears: rational and irrational — or, in simpler terms, fears that make sense and fears that don’t. For instance, the Baudelaire orphans have a fear of Count Olaf, which makes perfect sense, because he is an evil man who wants to destroy them. But if they were afraid of lemon meringue pie, this would be an irrational fear, because lemon meringue pie is delicious and would never hurt a soul. Being afraid of a monster under the bed is perfectly rational, because there may in fact be a monster under your bed at any time, ready to eat you all up, but fear of realtors is an irrational fear. Realtors, as I’m sure you know, are people who assist in the buying and selling of houses. Besides occasionally wearing an ugly yellow coat, the worst a realtor can do to you is show you a house that you find ugly, so it is completely irrational to be terrified of them.

Great art is as irrational as great music. It is mad with its own loveliness.

More quotes by Nathan, George Jean

Protestant theology has restricted the meaning of Faith too much — explaining it as subjective assurance or trust. It has sometimes been assumed that this attitude of throwing oneself into the arms of Divine grace may dispense us from the duty of forming rational convictions, and of directing our lives in accordance with them. Faith and fact come to be divorced. Either they are supposed to be directed to different objects, or we are told that the same proposition may be true for faith and false for science — in which case we are on a quicksand, and are driven to play fast and loose with veracity.

More quotes by Inge, William Ralph

Idiosyncratic belief systems which are shared by only a few adherents are likely to be regarded as delusional. Belief systems which may be just as irrational but which are shared by millions are called world religions. When comparing the beliefs held by psychotics with the religious beliefs held by normal people, it is impossible to say that one set of beliefs is delusional while the other is sane.

Anger is the common substitute for logic among those who have no evidence for what they desperately want to believe.

More quotes by Twain, Mark

To argue with a man who has renounced the use and authority of reason, and whose philosophy consists in holding humanity in contempt, is like administering medicine to the dead, or endeavoring to convert an Atheist by scripture.

Thomas Paine (1737-1809) American political philosopher and writer
The American Crisis #5, “To General Sir William Howe” (23 Mar 1778)
    (Source)

Sometimes shortened as: "To argue with a man who has renounced his reason is like giving medicine to the dead."

More quotes by ~Other

History warns us, however, that it is the customary fate of new truths to begin as heresies and to end as superstitions; and, as matters now stand, it is hardly rash to anticipate that, in another twenty years, the new generation, educated under the influences of the present day, will be in danger of accepting the main doctrines of the ‘Origin of Species’ with as little reflection, and it may be with as little justification, as so many of our contemporaries, twenty years ago, rejected them. Against any such a consummation let us all devoutly pray; for the scientific spirit is of more value than its products, and irrationally held truths may be more harmful than reasoned errors.
