Whenever a theory appears to you as the only possible one, take this as a sign that you have neither understood the theory nor the problem which it was intended to solve. ~ Karl Popper (born 28 July 1902) in Objective Knowledge: An Evolutionary Approach (1972)
We are social creatures to the inmost centre of our being. The notion that one can begin anything at all from scratch, free from the past, or unindebted to others, could not conceivably be more wrong. ~ Karl Popper
We do not choose political freedom because it promises us this or that. We choose it because it makes possible the only dignified form of human coexistence, the only form in which we can be fully responsible for ourselves. Whether we realize its possibilities depends on all kinds of things — and above all on ourselves. ~ Karl Popper
The World is charged with the grandeur of God. It will flame out, like shining from shook foil; It gathers to a greatness, like the ooze of oil Crushed. Why do men then now not reck his rod? Generations have trod, have trod, have trod; And all is seared with trade; bleared, smeared with toil; And wears man’s smudge and shares man’s smell: the soil Is bare now, nor can foot feel, being shod.
And for all this, nature is never spent; There lives the dearest freshness deep down things; And though the last lights off the black West went Oh morning, at the brown brink eastward, springs — Because the Holy Ghost over the bent World broods with the warm breast and with ah! bright wings. ~ Gerard Manley Hopkins ~
A rationalist is simply someone for whom it is more important to learn than to be provedright; someone who is willing to learn from others — not by simply taking over another's opinions, but by gladly allowing others to criticize his ideas and by gladly criticizing the ideas of others. The emphasis here is on the idea of criticism or, to be more precise, critical discussion. The genuine rationalist does not think that he or anyone else is in possession of the truth; nor does he think that mere criticism as such helps us achieve new ideas. But he does think that, in the sphere of ideas, only critical discussion can help us sort the wheat from the chaff. He is well aware that acceptance or rejection of an idea is never a purely rational matter; but he thinks that only critical discussion can give us the maturity to see an idea from more and more sides and to make a correct judgement of it.
I want to say this one thing, it's been almost an obsession with me, all I keep thinking of is this line from a musicalcomedy... and the song he loved most came at the very end of this record, the last side of Camelot, sadCamelot... "Don't let it be forgot, that once there was a spot, for one brief shining moment that was known as Camelot."
O the mind, mind has mountains; cliffs of fall Frightful, sheer, no-man-fathomed. Hold them cheap May who ne’er hung there. Nor does long our small Durance deal with that steep or deep. Here! creep, Wretch, under a comfort serves in a whirlwind: all Lifedeath does end and each day dies with sleep.
Before we as individuals are even conscious of our existence we have been profoundly influenced for a considerable time (since before birth) by our relationship to other individuals who have complicatedhistories, and are members of a society which has an infinitely more complicated and longer history than they do (and are members of it at a particular time and place in that history); and by the time we are able to make conscious choices we are already making use of categories in a language which has reached a particular degree of development through the lives of countless generations of human beings before us. . . . We are social creatures to the inmost centre of our being. The notion that one can begin anything at all from scratch, free from the past, or unindebted to others, could not conceivably be more wrong.
There are all kinds of sources of our knowledge; but none has authority … The fundamental mistake made by the philosophicaltheory of the ultimate sources of our knowledge is that it does not distinguish clearly enough between questions of origin and questions of validity.
The Quote of the Day (QOTD) is a prominent feature of the Wikiquote Main Page. Thank you for submitting, reviewing, and ranking suggestions!
4 : Excellent – should definitely be used. (This is the utmost ranking and should be used by any editor for only one quote at a time for each date.)
3 : Very Good – strong desire to see it used.
2 : Good – some desire to see it used.
1 : Acceptable – but with no particular desire to see it used.
0 : Not acceptable – not appropriate for use as a quote of the day.
An averaging of the rankings provided to each suggestion produces it’s general ranking in considerations for selection of Quote of the Day. The selections made are usually chosen from the top ranked options existing on the page, but the provision of highly ranked late additions, especially in regard to special events (most commonly in regard to the deaths of famous people, or other major social or physical occurrences), always remain an option for final selections.
There is no history of mankind, there is only an indefinite number of histories of all kinds of aspects of humanlife. And one of these is the history of politicalpower. This is elevated into the history of the world. But this, I hold, is an offence against every decent conception of mankind. It is hardly better than to treat the history of embezzlement or of robbery or of poisoning as the history of mankind. For the history of power politics is nothing but the history of international crime and mass murder (including it is true, some of the attempts to suppress them). This history is taught in schools, and some of the greatest criminals are extolled as heroes.
This civilization has not yet fully recovered from the shock of its birth — the transition from the tribal or "enclosed society," with its submission to magicalforces, to the 'open society' which sets free the critical powers of man … the shock of this transition is one of the factors that have made possible the rise of those reactionary movements which have tried, and still try, to overthrow civilization and to return to tribalism.
What a monument of human smallness is this idea of the philosopher king. What a contrast between it and the simplicity of humaneness of Socrates, who warned the statesmen against the danger of being dazzled by his own power, excellence, and wisdom, and who tried to teach him what matters most — that we are all frail human beings. What a decline from this world of irony and reason and truthfulness down to Plato's kingdom of the sage whose magical powers raise him high above ordinary men; although not quite high enough to forgo the use of lies, or to neglect the sorry trade of every shaman — the selling of spells, of breeding spells, in exchange for power over his fellow-men.
Piecemeal social engineering resembles physical engineering in regarding the ends as beyond the province of technology. (All that technology may say about ends is whether they are compatible with each other or realizable.)
There is an almost universal tendency, perhaps an inborn tendency, to suspect the good faith of a man who holds opinions that differ from our own opinions. … It obviously endangers the freedom and the objectivity of our discussion if we attack a person instead of attacking an opinion or, more precisely, a theory.
Bold ideas, unjustified anticipations, and speculative thought, are our only means for interpreting nature: our only organon, our only instrument, for grasping her. And we must hazard them to win our prize. Those among us who are unwilling to expose their ideas to the hazard of refutation do not take part in the scientific game.
Not only do I hate violence, but I firmly believe that the fight against it is not hopeless. I realize that the task is difficult. I realize that, only too often in the course of history, it has happened that what appeared at first to be a great success in the fight against violence was followed by a defeat. I do not overlook the fact that the new age of violence which was opened by the two World wars is by no means at an end. Nazism and Fascism are thoroughly beaten, but I must admit that their defeat does not mean that barbarism and brutality have been defeated. On the contrary, it is no use closing our eyes to the fact that these hateful ideas achieved something like a victory in defeat. I have to admit that Hitler succeeded in degrading the moral standards of our Western world, and that in the world of today there is more violence and brutal force than would have been tolerated even in the decade after the first World war. And we must face the possibility that our civilization may ultimately be destroyed by those new weapons which Hitlerism wished upon us, perhaps even within the first decade after the second World war; for no doubt the spirit of Hitlerism won its greatest victory over us when, after its defeat, we used the weapons which the threat of Nazism had induced us to develop.
It is often asserted that discussion is only possible between people who have a common language and accept common basic assumptions. I think that this is a mistake. All that is needed is a readiness to learn from one's partner in the discussion, which includes a genuine wish to understand what he intends to say. If this readiness is there, the discussion will be the more fruitful the more the partner's backgrounds differ.
The true Enlightenment thinker, the true rationalist, never wants to talk anyone into anything. No, he does not even want to convince; all the time he is aware that he may be wrong. Above all, he values the intellectual independence of others too highly to want to convince them in important matters. He would much rather invite contradiction, preferably in the form of rational and disciplined criticism. He seeks not to convince but to arouse — to challenge others to form free opinions.
