I must remind you that our credulity is not to be measured by the truth of the things we believe. When men believed that the earthwas flat, they were not credulous: they were using their common sense, and, if asked to prove that the earth was flat, would have said simply, "Look at it." Those who refuse to believe that it is round are exercising a wholesome skepticism.
George Bernard ShawNobody can live in society without conventions. The reason why sensible people are as conventional as they can bear to be is that conventionality saves so much time and thought and trouble and social friction of one sort or another that it leaves them much more leisure time for freedom than unconventionality does.
George Bernard ShawIf history repeats itself, and the unexpected always happens, how incapable must Man be of learning from experience.
