The process of finding the truth may not be a process by which we feel increasingly better and better. It may be a process by which we look at things honestly, sincerely, truthfully, and that may or may not be an easy thing to do.
The reaction to any word may be, in an individual, either a mob-reaction or an individual reaction. It is up to the individual to ask himself: Is my reaction individual, or am I merely reacting from my mob-self? When it comes to the so-called obscene words, I should say that hardly one person in a million escapes mob-reaction.
The best that Gauss has given us was likewise an exclusive production. If he had not created his geometry of surfaces, which served Riemann as a basis, it is scarcely conceivable that anyone else would have discovered it. I do not hesitate to confess that to a certain extent a similar pleasure may be found by absorbing ourselves in questions of pure geometry.
We become aware, however, that all customs, even the hardest, grow pleasanter and milder with time, and that the severest way of life may become a habit and therefore a pleasure.
