So the problem is not so much to see what nobody has yet seen, as to think what nobody has yet thought concerning that which everybody sees. - Arthur Schopenhauer

The more unintelligent a man is, the less mysterious existence seems to him.

Men best show their character in trifles, where they are not on their guard. It is in the simplest habits, that we often see the boundless egotism which pays no regard to the feelings of others and denies nothing to itself.

And now that I have allowed myself the jest to which in this two-sided life hardly any page can be too serious to grant a place, I part with the book with deep seriousness, in the sure hope that sooner or later it will reach those to whom alone it can be addressed; and for the rest, patiently resigned that the same fate should, in full measure, befall it, that in all ages has, to some extent, befallen all knowledge, and especially the weightiest knowledge of the truth, to which only a brief triumph is allotted between the two long periods in which it is condemned as paradoxical or disparaged as trivial. The former fate is also wont to befall its author. But life is short, and truth works far and lives long: let us speak the truth.
