All truth passes through three stages. First, it is ridiculed. Second, it is violently opposed. Third, it is accepted as being self-evident.
Arthur SchopenhauerA reproach can only hurt if it hits the mark. Whoever knows that he does not deserve a reproach can treat it with contempt.
Arthur SchopenhauerThe discovery of truth is prevented more effectively, not by the false appearance things present and which mislead into error, not directly by weakness of the reasoning powers, but by preconceived opinion, by prejudice.
