I have often wondered how it is that every man loves himself more than all the rest of men, but yet sets less value on his own opinion of himself than on the opinion of others.

Public opinion is a permeating influence, and it exacts obedience to itself; it requires us to think other men's thoughts, to speak other men's words, to follow other men's habits.

The man who never alters his opinion is like standing water, and breeds reptiles of the mind.

Vanity, indeed, is the very antidote to conceit; for while the former makes us all nerve to the opinion of others, the latter is perfectly satisfied with its opinion of itself.

Solitude has but one disadvantage - it is apt to give one too high an opinion of one’s self. In the world we are sure to be often reminded of every known or supposed defect we may have.

The world is governed much more by opinion than by laws. It is not the judgment of courts, but the moral judgment of individuals and masses of men, which is the chief wall of defence around property and life. With the progress of society, this power of opinion is taking the place of arms.

No man on earth is truly free. All are slaves of money or necessity. Public opinion or fear of prosecution forces each one, against his conscience, to conform.

Our opinion of people depends less upon what we see in them than in what they make us see in ourselves.

Worldly ambition is founded on pride or envy, but emulation, or laudable ambition, is actually founded in humility; for it evidently implies that we have a low opinion of our present attainments, and think it necessary to be advanced.

The mischief of flattery is, not that it persuades any man that he is what he is not, but that it suppresses the influence of honest ambition by raising an opinion that honor may be gained without the toil of merit.

Too often we... enjoy the comfort of opinion without the discomfort of thought.

We enter our studies, and enjoy a society which we alone can bring together. We raise no jealousy by conversing with one in preference to another; we give no offense to the most illustrious by questioning him as long as we will, and leaving him as abruptly. Diversity of opinion raises no tumult in our presence: each interlocutor stands before us, speaks or is silence, and we adjourn or decide the business at our leisure.

Risk! Risk anything! Care no more for the opinion of others, for those voices. Do the hardest thing on earth for you. Act for yourself. Face the truth.

I care not so much what I am in the opinion of others, as what I am in my own; I would be rich of myself, and not by borrowing.

One often contradicts an opinion when it is really only the tone in which it has been presented that is unsympathetic.

The falseness of an opinion is not for us any objection to it. The question is how far it is life-furthering, life-preserving, species-preserving.

It is safer to learn than teach; and who conceals his opinion has nothing to answer for.

The very purpose of existence is to reconcile the glowing opinion we hold of ourselves with the appalling things that other people think about us.

The savage lives within himself, while social man lives constantly outside himself, and only knows how to live in the opinion of others, so that he seems to receive the consciousness of his own existence merely from the judgment of others concerning him.

When a law is proposed in the people’s assembly, what is asked of them is not precisely whether they approve of the proposition or reject it, but whether it is in conforming with the general will which is theirs; each by giving his vote gives his opinion on this question, and the counting of votes yields a declaration of the general will. When, therefore, the opinion contrary to my own prevails, this proves only that I have made a mistake, and that what I believed to be the general will was not so. If my particular opinion had prevailed against the general will, I should have done something other than what I had willed, and then I should not have been free. This presupposes, it is true, that all characteristics of the general will are still to be found in the majority; when these cease to be there, no matter what position men adopt, there is no longer any freedom.
