# Quote — Jean Jacques Rousseau, Emile; or On Education

> I cannot understand how any one can be a sceptic sincerely and on principle. Either such philosophers do not exist or they are the most miserable of men. Doubt with regard to what we ought to know is a condition too violent for the human mind; it cannot long be endured; in spite of itself the mind decides one way or another, and it prefers to be deceived rather than to believe nothing.
