It is hard enough to remember my opinions, without also remembering my reasons for them!
Friedrich Nietzsche
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
Opinions have vested interests just as men have.
Samuel Butler
Opinions is a species of property - I am always desirous of sharing
Charles Lamb
Opinions are to the vast apparatus of social existence what oil is to machines: one does not go up to a turbine and pour machine oil over it; one applies a little to hidden spindles and joints that one has to know.
Walter Benjamin
It is as certain that many opinions, now general, will be rejected by future ages, as it is that many, once general, are rejected by the present

Opinions cannot survive if one has no chance to fight for them
Thomas Mann
Opinions founded on prejudice are always sustained with the greatest violence
Hebrew Proverb
Those who never retract their opinions love themselves more than they love the truth.
Joseph Joubert
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
Opinions are made to be changed -or how is truth to be got at?
Lord Byron
So many men, so many opinions
Terence
The opinions which we hold of one another, our relations with friends and kinfolk are in no sense permanent, save in appearance, but are as eternally fluid as the sea itself

The foolish and the dead alone never change their opinions.
James Russell Lowell
