A Quote by Galileo Galilei

I would beg the wise and learned fathers (of the church) to consider with all diligence the difference which exists between matters of mere opinion and matters of demonstration. ... [I]t is not in the power of professors of the demonstrative sciences to alter their opinions at will, so as to be now of one way of thinking and now of another. ... [D]emonstrated conclusions about things in nature of the heavens, do not admit of being altered with the same ease as opinions to what is permissible or not, under a contract, mortgage, or bill of exchange.

I would beg the wise and learned fathers [of the church] to consider with all diligence the difference which exists between matters of mere opinion and matters of demonstration.

Galileo Galilei

I can tell by my own reaction to it that this book is harmful." But let him only wait and perhaps one day he will admit to himself that this same book has done him a great service by bringing out the hidden sickness of his heart and making it visible.— Altered opinions do not alter a man’s character (or do so very little); but they do illuminate individual aspects of the constellation of his personality which with a different constellation of opinions had hitherto remained dark and unrecognizable.

Friedrich Nietzsche

Now the relation which, in the sphere of nature, being and semblance or sensation bear to one another in this antithesis, is the same as that which in ethics exists between good and pleasure or feeling.

Friedrich Schleiermacher

Liberal education, which consists in the constant intercourse with the greatest minds, is a training in the highest form of modesty. ... It is at the same time a training in boldness. ... It demands from us the boldness implied in the resolve to regard the accepted views as mere opinions, or to regard the average opinions as extreme opinions which are at least as likely to be wrong as the most strange or least popular opinions

Leo Strauss

Most boys or youths who have had much knowledge drilled into them, have their mental capacities not strengthened, but overlaid by it. They are crammed with mere facts, and with the opinions and phrases of other people, and these are accepted as a substitute for the power to form opinions of their own. And thus, the sons of eminent fathers, who have spared no pains in their education, so often grow up mere parroters of what they have learnt, incapable of using their minds except in the furrows traced for them.

John Stuart Mill

Those who are greatly occupied in physical or material matters lack sufficient knowledge or have only superficial understanding of spiritual matters. Therefore, such people's opinions and judgments concerning spiritual matters carry no weight.

Said Nursi

It's as if scientists exert every effort of will they possess deliberately to find the least significant problems in the world and explain them. Art matters. Happiness matters. Love matters. Good matters. Evil matters. Slam the fridge door. They are the only things that matter and they are of course precisely the things that science goes out of its way to ignore.

Stephen Fry

When I signed my movie contract, I thought I could never even have an opinion on a movie. But now, I've realized I have a lot of opinions.

Anna Todd

The best way to avoid falling prey to the opinions of others is to realize that other people's opinions are just that - opinions. Regardless of how great or terrible they think you are, that's only their opinion. Your true self-worth comes from within.

Travis Bradberry

If an opinion contrary to your own makes you angry, that is a sign that you are subsciously aware of having no good reason for thinking as you do. [...] The most savage controversies are those about matters as to which there is no good evidence either way. Persecution is used in theology, not in arithmetic, because in arithmetic there is knowledge, but in theology there is only opinion. So whenever you find yourself getting angry about a difference of opinion, be on your guard; you will probably find, on examination, that your belief is going beyond what the evidence warrants.

Bertrand Russell

The knowledge of Natural-History, being Observation of Matters of Fact, is more certain than most others, and in my slender Opinion, less subject to Mistakes than Reasonings, Hypotheses, and Deductions are; ... These are things we are sure of, so far as our Senses are not fallible; and which, in probability, have been ever since the Creation, and will remain to the End of the World, in the same Condition we now find them.

Hans Sloane

Nothing but good can result from an exchange of information and opinions between those whose circumstances and morals admit no doubt of the integrity of their views.

Thomas Jefferson

Voting, we might even say, is the next to last refuge of the politically impotent. The last refuge is, of course, giving your opinion to a pollster, who will get a version of it through a desiccated question, and then will submerge it in a Niagara of similar opinions, and convert them into--what else?--another piece of news. Thus we have here a great loop of impotence: The news elicits from you a variety of opinions about which you can do nothing except to offer them as more news, about which you can do nothing.

Neil Postman

Conventional opinions fit so comfortably into the dominant paradigm as to be seen not as opinions but as statements of fact, as 'the nature of things.' The very efficacy of opinion manipulation rests on the fact that we do not know we are being manipulated. The most insidious forms of oppression are those that so insinuate themselves into our communication universe and the recesses of our minds that we do not even realize they are acting upon us.

Michael Parenti

I make up my opinions from facts and reasoning, and not to suit any body but myself. If people don't like my opinions, it makes little difference as I don't solicit their opinions or votes.

William Tecumseh Sherman

Trump's opinions on the Iraq War have been as erratic as his opinions on other foreign policy matters - such as his careless position to think more countries should acquire nuclear weapons.
