No rose without a thorn but many a thorn without a rose. - Arthur Schopenhauer

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.

The 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.

In endless space countless luminous spheres, round each of which some dozen smaller illuminated ones revolve, hot at the core and covered over with a hard cold crust; on this crust a mouldy film has produced living and knowing beings: this is empirical truth, the real, the world. Yet for a being who thinks, it is a precarious position to stand on one of those numberless spheres freely floating in boundless space, without knowing whence or whither, and to be only one of innumerable similar beings that throng, press, and toil, restlessly and rapidly arising and passing away in beginningless and endless time.
