An opinion is a person's ideas and thoughts towards something. It is an assessment, judgment or evaluation of something.


  • If all mankind minus one were of one opinion, and only one person were of the contrary opinion, mankind would be no more justified in silencing that one person, than he, if he had the power, would be justified in silencing mankind. --John Stuart Mill, On Liberty (1859).
  • The peculiar evil of silencing the expression of an opinion is, that it is robbing the human race; posterity as well as the existing generation; those who dissent from the opinion, still more than those who hold it. If the opinion is right, they are deprived of the opportunity of exchanging error for truth: if wrong, they lose, what is almost as great a benefit, the clearer perception and livelier impression of truth, produced by its collision with error. --John Stuart Mill, On Liberty (1859).
  • To refuse a hearing to an opinion, because they are sure that it is false, is to assume that their certainty is the same thing as absolute certainty. All silencing of discussion is an assumption of infallibility. Its condemnation may be allowed to rest on this common argument, not the worse for being common. --John Stuart Mill, On Liberty (1859).


  • Everyone is entitled to his own opinion, but not his own facts.

  • Too often we enjoy the comfort of opinion without the discomfort of thought.
  • The point is not to take the world's opinion as a guiding star but to go one's way in life and working unerringly, neither depressed by failure nor seduced by applause.
  • The only opinion that matters is one's own.
  • Opinions are like assholes; everyone's got one.
  • If I want your opinion, I will tell it to you.
  • Opinions should be formed with great caution, and changed with greater.
    • H.W. Shaw
  • 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.
  • He who has no opinion of his own, but depends upon the opinion and taste of others, is a slave.
    • Klopstock
  • To maintain an opinion because it is thine, and not because it is true, is to prefer thyself above the truth.
    • Venning
  • We should always keep a corner of our heads open and free, that we may make room for the opinions of our friends. Let us have heart and head hospitality.
    • Joubert
  • No liberal man would impute a charge of unsteadiness to another for having changed his opinion.
  • Who observes not that the voice of the people, yea of that people that voiced themselves the people of God, did prosecute the God of all people, with one common voice, "He is worthy to die." I will not, therefore, ambitiously beg their voices for my preferment; nor weigh my worth in that uneven balance, in which a feather of opinion shall be moment enough to turn the scales and make a light piece go current, and a current piece seem light.
    • Arthur Warwick

  • People with opinions just go around bothering each other.
  • People in supervising positions in investigation are supposed to give too much of their opinion and if they are wrong saying "sorry" is enough.
    • Nate River
