“It has always been asked in the spirit of: ‘What are the best sources of our knowledge – the most reliable ones, those which will not lead us into error, and those to which we can and must turn, in case of doubt, as the last court of appeal?’ I propose to assume, instead, that no such ideal sources exist – no more than ideal rulers – and that all ‘sources’ are liable to lead us into errors at times. And I propose to replace, therefore, the question of the sources of our knowledge by the entirely different question: ‘How can we hope to detect and eliminate error?’ The question of the sources of our knowledge, like so many authoritarian questions, is a genetic one. It asks for the origin of our knowledge, in the belief that knowledge may legitimize itself by its pedigree. The nobility of the racially pure knowledge, the untainted knowledge, the knowledge which derives from the highest authority, if possible from God: these are the (often unconscious) metaphysical ideas behind the question. My modified question, ‘How can we hope to detect error?’ may be said to derive from the view that such pure, untainted and certain sources do not exist, and that questions of origin or of purity should not be confounded with questions of validity, or of truth. …. The proper answer to my question ‘How can we hope to detect and eliminate error?’ is I believe, ‘By criticizing the theories or guesses of others and – if we can train ourselves to do so – by criticizing our own theories or guesses.’ …. So my answer to the questions ‘How do you know? What is the source or the basis of your assertion? What observations have led you to it?’ would be: ‘I do not know: my assertion was merely a guess. Never mind the source, or the sources, from which it may spring – there are many possible sources, and I may not be aware of half of them; and origins or pedigrees have in any case little bearing upon truth. But if you are interested in the problem which I tried to solve by my tentative assertion, you may help me by criticizing it as severely as you can; and if you can design some experimental test which you think might refute my assertion, I shall gladly, and to the best of my powers, help you to refute it.”
― Karl Popper

“The gods did not reveal, from the beginning,
All things to us, but in the course of time
Through seeking we may learn and know things better.
But as for certain truth, no man has known it,
Nor shall he know it,neither of the gods
Nor yet of all the things of which I speak.
For even if by chance he were to utter
The final truth, he would himself not know it:
For all is but a woven web of guesses”
― Xenophanes

“Whenever we read the obscene stories, the voluptuous debaucheries, the cruel and torturous executions, the unrelenting vindictiveness, with which more than half the Bible is filled, it would be more consistent that we called it the word of a demon, than the word of God. It is a history of wickedness, that has served to corrupt and brutalize mankind; and, for my part, I sincerely detest it, as I detest everything that is cruel.”
― Thomas Paine, The Age of Reason

“The ambition of domineering over the mind, is one of the strongest passions. A theologian, a missionary, or a partisan of any description, is always for conquering like a prince, and there are many more sects than there are sovereigns in the world…. I conclude, that every sensible man, every honest man, ought to hold Christianity in abhorrence. ‘The great name of Theist, which we can never sufficiently revere,’ is the only name we ought to adopt. The only gospel we should read is the grand book of nature, written with God’s own hand, and stamped with his own seal. The only religion we ought to profess is, 'to adore God, and act like honest men.’ It would be as impossible for this simple and eternal religion to produce evil, as it would be impossible for Christian fanaticism not to produce it…. But what shall we substitute in its place? say you. What? A ferocious animal has sucked the blood of my relatives. I tell you to rid yourselves of this beast, and you ask me what you shall put in its place! Is it you that put this question to me? Then you are a hundred times more odious than the Pagan Pontiffs, who permitted themselves to enjoy tranquility among their ceremonies and sacrifices, who did not attempt to enslave the mind by dogmas, who never disputed the powers of the magistrates, and who introduced no discord among mankind. You have the face to ask what you must substitute in the place of your fables!”
― Voltaire
