Opinions have vested interests just as men have.
Samuel Butler
Do not fear to be eccentric in opinion, for every opinion now accepted was once eccentric.
Bertrand Russell
Do not think of knocking out another person's brains because he differs in opinion from you. It would be as rational to knock yourself on the head because you differ from yourself ten years ago.
Horace Mann
False opinions are like false money, struck first of all by guilty men and thereafter circulated by honest people who perpetuate the crime without knowing what they are doing.
Joseph Marie de Maistre
I think we ought always to entertain our opinions with some measure of doubt. I shouldn't wish people dogmatically to believe any philosophy, not even mine.
Bertrand Russell
It is hard enough to remember my opinions, without also remembering my reasons for them!
Friedrich Nietzsche
Men get opinions as boys learn to spell, By reiteration chiefly.
Elizabeth Barrett Browning
The fact that an opinion has been widely held is no evidence whatever that it is not utterly absurd; indeed in view of the silliness of the majority of mankind, a widespread belief is more likely to be foolish than sensible.
Bertrand Russell
The moment we begin to fear the opinions of others and hesitate to tell the truth that is in us, and from motives of policy are silent when we should speak, the divine floods of light and life no longer flow into our souls.
Elizabeth Cady Stanton
Fight for your opinions, but do not believe that they contain the whole truth, or the only truth.
Charles A. Dana
The recipe for perpetual ignorance is: be satisfied with your opinions and content with your knowledge.
Elbert Hubbard
Risk! Risk anything! Care no more for the opinions of others, for those voices. Do the hardest thing on earth for you. Act for yourself. Face the truth.
Katherine Mansfield
