I am aware that a philosopher's ideas are not subject to the judgment of ordinary persons, because it is his endeavour to seek the truth in all things, to the extent permitted to human reason by God. - Nicolaus Copernicus
Moreover, since the sun remains stationary, whatever appears as a motion of the sun is really due rather to the motion of the earth. - Nicolaus Copernicus
Mathematics is written for mathematicians. - Nicolaus Copernicus
The earth together with its surrounding waters must in fact have such a shape as its shadow reveals, for it eclipses the moon with the arc of a perfect circle. - Nicolaus Copernicus
Those things which I am saying now may be obscure, yet they will be made clearer in their proper place. - Nicolaus Copernicus
For I am not so enamoured of my own opinions that I disregard what others may think of them. - Nicolaus Copernicus
At rest, however, in the middle of everything is the sun. - Nicolaus Copernicus
Finally we shall place the Sun himself at the center of the Universe. - Nicolaus Copernicus
Of all things visible, the highest is the heaven of the fixed stars. - Nicolaus Copernicus
To know that we know what we know, and to know that we do not know what we do not know, that is true knowledge. - Nicolaus Copernicus

“You cannot teach a man anything, you can only help him find it within himself.” - Galileo
“In questions of science, the authority of a thousand is not worth the humble reasoning of a single individual.” - Galileo Galilei
“All truths are easy to understand once they are discovered; the point is to discover them.” - Galileo
“Philosophy [nature] is written in that great book which ever is before our eyes -- I mean the universe -- but we cannot understand it if we do not first learn the language and grasp the symbols in which it is written. The book is written in mathematical language, and the symbols are triangles, circles and other geometrical figures, without whose help it is impossible to comprehend a single word of it; without which one wanders in vain through a dark labyrinth.” - Galileo
“Passion is the genesis of genius.” - Galileo Galilei
“The sun, with all those planets revolving around it and dependent on it, can still ripen a bunch of grapes as if it had nothing else in the universe to do.” - Galileo Galilei
“Sì perché l'autorità dell'opinione di mille nelle scienze non val per una scintilla di ragione di un solo, sì perché le presenti osservazioni spogliano d'autorità i decreti de' passati scrittori, i quali se vedute l'avessero, avrebbono diversamente determinato.
For in the sciences the authority of thousands of opinions is not worth as much as one tiny spark of reason in an individual man. Besides, the modern observations deprive all former writers of any authority, since if they had seen what we see, they would have judged as we judge.” - Galileo Galilei
“It is a beautiful and delightful sight to behold the body of the Moon.” - Galileo Galilei
“Wine is sunlight, held together by water.” - Galileo Galilei
“If I have seen further it is by standing on the shoulders of Giants.” - Isaac Newton

“Truth is ever to be found in the simplicity, and not in the multiplicity and confusion of things.” - Isaac Newton
“No great discovery was ever made without a bold guess.” - Isaac Newton
“This most beautiful system of the sun, planets and comets, could only proceed from the counsel and dominion of an intelligent and powerful Being...
This Being governs all things, not as the soul of the world, but as Lord over all; and on account of his dominion he is wont, to be called Lord God παντοκρατωρ or Universal Ruler.” - Isaac Newton
“A man may imagine things that are false, but he can only understand things that are true.” - Sir Isaac Newton
“If I had my life to live over again, I would have made a rule to read some poetry and listen to some music at least once every week.” - Charles Darwin
“A man who dares to waste one hour of time has not discovered the value of life.” - Charles Darwin
“Ignorance more frequently begets confidence than does knowledge: it is those who know little, not those who know much, who so positively assert that this or that problem will never be solved by science.” - Charles Darwin
“Thus, from the war of nature, from famine and death, the most exalted object which we are capable of conceiving, namely, the production of the higher animals, directly follows. There is grandeur in this view of life, with its several powers, having been originally breathed into a few forms or into one; and that, whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been, and are being, evolved.” - Charles Darwin
“If the misery of the poor be caused not by the laws of nature, but by our institutions, great is our sin.” - Charles Darwin

“The love for all living creatures is the most noble attribute of man.” - Charles Darwin
“I am not apt to follow blindly the lead of other men” - Charles Darwin
“It is not the strongest of the species that survives,
not the most intelligent that survives.
It is the one that is the most adaptable to change.” - Charles Darwin
“...Whilst on board the Beagle I was quite orthodox, and I remember being heartily laughed at by several of the officers... for quoting the Bible as an unanswerable authority on some point of morality... But I had gradually come by this time, i.e., 1836 to 1839, to see that the Old Testament from its manifestly false history of the world, with the Tower of Babel, the rainbow at sign, &c., &c., and from its attributing to God the feelings of a revengeful tyrant, was no more to be trusted than the sacred books of the Hindoos, or the beliefs of any barbarian.
...By further reflecting that the clearest evidence would be requisite to make any sane man believe in the miracles by which Christianity is supported, (and that the more we know of the fixed laws of nature the more incredible do miracles become), that the men at that time were ignorant and credulous to a degree almost uncomprehensible by us, that the Gospels cannot be proved to have been written simultaneously with the events, that they differ in many important details, far too important, as it seemed to me, to be admitted as the usual inaccuracies of eyewitnesses; by such reflections as these, which I give not as having the least novelty or value, but as they influenced me, I gradually came to disbelieve in Christianity as a divine revelation. The fact that many false religions have spread over large portions of the earth like wild-fire had some weight with me. Beautiful as is the morality of the New Testament, it can be hardly denied that its perfection depends in part on the interpretation which we now put on metaphors and allegories.
But I was very unwilling to give up my belief... Thus disbelief crept over me at a very slow rate, but was at last complete. The rate was so slow that I felt no distress, and have never since doubted even for a single second that my conclusion was correct. I can indeed hardly see how anyone ought to wish Christianity to be true; for if so the plain language of the text seems to show that the men who do not believe, and this would include my Father, Brother and almost all of my friends, will be everlastingly punished.
And this is a damnable doctrine.” - Charles Darwin
“The mystery of the beginning of all things is insoluble by us; and I for one must be content to remain an agnostic.” - Charles Darwin
GREAT QUOTES OF FAMOUS ECONOMISTS GREAT QUOTES OF ADAM SMITH
“The great source of both the misery and disorders of human life, seems to arise from over-rating the difference between one permanent situation and another. Avarice over-rates the difference between poverty and riches: ambition, that between a private and a public station: vain-glory, that between obscurity and extensive reputation. The person under the influence of any of those extravagant passions, is not only miserable in his actual situation, but is often disposed to disturb the peace of society, in order to arrive at that which he so foolishly admires. The slightest observation, however, might satisfy him, that, in all the ordinary situations of human life, a well-disposed mind may be equally calm, equally cheerful, and equally contented. Some of those situations may, no doubt, deserve to be preferred to others: but none of them can deserve to be pursued with that passionate ardour which drives us to violate the rules either of prudence or of justice; or to corrupt the future tranquillity of our minds, either by shame from the remembrance of our own folly, or by remorse from the horror of our own injustice.” - Adam Smith
“Civil government, so far as it is instituted for the security of property, is in reality instituted for the defense of the rich against the poor, or of those who have some property against those who have none at all.” - Adam Smith
“Science is the great antidote to the poison of enthusiasm and superstition.” - Adam Smith
“The first thing you have to know is yourself. A man who knows himself can step outside himself and watch his own reactions like an observer.” - Adam Smith
“It is not from the benevolence of the butcher, the brewer, or the baker that we expect our dinner, but from their regard to their own self-interest. We address ourselves not to their humanity but to their self-love, and never talk to them of our own necessities, but of their advantages” - Adam Smith
“Never complain of that of which it is at all times in your power to rid yourself.” - Adam Smith
“The man whose whole life is spent in performing a few simple operations, of which the effects are perhaps always the same, or very nearly the same, has no occasion to exert his understanding or to exercise his invention in finding out expedients for removing difficulties which never occur. He naturally loses, therefore, the habit of such exertion, and generally becomes as stupid and ignorant as it is possible for a human creature to become. ” - Adam Smith
“Mercy to the guilty is cruelty to the innocent.” - Adam Smith
“No society can surely be flourishing and happy of which by far the greater part of the numbers are poor and miserable.” - Adam Smith
“In regards to the price of commodities, the rise of wages operates as simple interest does, the rise of profit operates like compound interest.
Our merchants and masters complain much of the bad effects of high wages in raising the price and lessening the sale of goods. They say nothing concerning the bad effects of high profits. They are silent with regard to the pernicious effects of their own gains. They complain only of those of other people.” - Adam Smith
“have never understood why it is "greed" to want to keep the money you have earned but not greed to want to take somebody else's money.” - Thomas Sowell
“When you want to help people, you tell them the truth. When you want to help yourself, you tell them what they want to hear.” - Thomas Sowell
“It’s amazing how much panic one honest man can spread among a multitude of hypocrites.” - Thomas Sowell
“People who pride themselves on their "complexity" and deride others for being "simplistic" should realize that the truth is often not very complicated. What gets complex is evading the truth.” - Thomas Sowell,
“The first lesson of economics is scarcity: There is never enough of anything to satisfy all those who want it. The first lesson of politics is to disregard the first lesson of economics.” - Thomas Sowell
“Much of the social history of the Western world over the past three decades has involved replacing what worked with what sounded good.” - Thomas Sowell
“The problem isn't that Johnny can't read. The problem isn't even that Johnny can't think. The problem is that Johnny doesn't know what thinking is; he confuses it with feeling.” - Thomas Sowell
“Intellect is not wisdom.” - Thomas Sowell
“Some of the biggest cases of mistaken identity are among intellectuals who have trouble remembering that they are not God.” - Thomas Sowell
“Racism does not have a good track record. It's been tried out for a long time and you'd think by now we'd want to put an end to it instead of putting it under new management.” - Thomas Sowell
“Socialism in general has a record of failure so blatant that only an intellectual could ignore or evade it.” - Thomas Sowell
“There are only two ways of telling the complete truth--anonymously and posthumously.” - Thomas Sowell
“Socialism is a wonderful idea. It is only as a reality that it has been disastrous. Among people of every race, color, and creed, all around the world, socialism has led to hunger in countries that used to have surplus food to export.... Nevertheless, for many of those who deal primarily in ideas, socialism remains an attractive idea -- in fact, seductive. Its every failure is explained away as due to the inadequacies of particular leaders.” - Thomas Sowell
“When my information changes, I alter my conclusions. What do you do, sir?” - John Maynard Keynes
“The ideas of economists and political philosophers, both when they are right and when they are wrong are more powerful than is commonly understood. Indeed, the world is ruled by little else. Practical men, who believe themselves to be quite exempt from any intellectual influences, are usually slaves of some defunct economist.” - John Maynard Keynes
“It is better to be roughly right than precisely wrong.” - John Maynard Keynes
“If you owe your bank a hundred pounds, you have a problem. But if you owe a million, it has.” - John Maynard Keynes
“Capitalism is the astounding belief that the most wickedest of men will do the most wickedest of things for the greatest good of everyone.” - John Maynard Keynes
“Practical men who believe themselves to be quite exempt from any intellectual influence, are usually the slaves of some defunct economist. Madmen in authority, who hear voices in the air, are distilling their frenzy from some academic scribbler of a few years back” - John Maynard Keynes
“The master-economist must possess a rare combination of gifts .... He must be mathematician, historian, statesman, philosopher—in some degree. He must understand symbols and speak in words. He must contemplate the particular, in terms of the general, and touch abstract and concrete in the same flight of thought. He must study the present in the light of the past for the purposes of the future. No part of man's nature or his institutions must be entirely outside his regard. He must be purposeful and disinterested in a simultaneous mood, as aloof and incorruptible as an artist, yet sometimes as near to earth as a politician.” - John Maynard Keynes
“The political problem of mankind is to combine three things: economic efficiency, social justice and individual liberty.” - John Maynard Keynes
“Words ought to be a little wild for they are the assault of thoughts on the unthinking.” - John Maynard Keynes
“The difficulty lies not so much in developing new ideas as in escaping from old ones.” - John Maynard Keynes
“Markets can remain irrational longer than you can remain solvent.” - John Maynard Keynes
