Some positive persisting fops we know, Who, if once wrong, will needs be always so; But you with pleasure own your errors past, And make each day a critique on the last.
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.
It is too often believed that a person in his progress towards perfection passes from error to truth; that when he passes on from one thought to another, he must necessarily reject the first. But no error can lead to truth. The soul passing through its different stages goes from truth to truth, and each stage is true; it goes from lower truth to higher truth.
Zarathustra was the first to consider the fight of good and evil the very wheel in the machinery of things: the transposition of morality into the metaphysical realm, as a force, cause, and end in itself, is his work. [...] Zarathustra created this most calamitous error, morality; consequently, he must also be the first to recognize it.
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.
I believe that I have really found the relationship between gravitation and electricity, assuming that the Miller experiments are based on a fundamental error. Otherwise, the whole relativity theory collapses like a house of cards.
And why are you so firmly, so triumphantly, convinced that only the normal and the positive--in other words, only what is conducive to welfare--is for the advantage of man? Is not reason in error as regards advantage? Does not man, perhaps, love something besides well-being? Perhaps he is just as fond of suffering? Perhaps suffering is just as great a benefit to him as well-being? Man is sometimes extraordinarily, passionately, in love with suffering, and that is a fact.
The majority of mankind would seem to be beguiled into error by pleasure, which, not being really a good, yet seems to be so. So that they indiscriminately choose as good whatsoever gives them pleasure, while they avoid all pain alike as evil.
