For as long as they praise you, never forget that it is not yet your own path that you walk, but another person's.

The 'kingdom of Heaven' is a condition of the heart - not something that comes 'upon the earth' or 'after death.'

Men were considered "free" only so that they might be considered guilty - could be judged and punished: consequently, every act had to be considered as willed, and the origin of every act had to be considered as lying within the consciousness (and thus the most fundamental psychological deception was made the principle of psychology itself).

History belongs above all to the man...who needs models, teachers, comforters and cannot find them among his contemporaries.

I am interested only in the relations of a people to the rearing of the individual man, and among the Greeks the conditions were unusually favourable for the development of the individual; not by any means owing to the goodness of the people, but because of the struggles of their evil instincts.With the help of favourable measures great individuals might be reared who would be both different from and higher than those who heretofore have owed their existence to mere chance. Here we may still be hopeful: in the rearing of exceptional men.

No one dies of fatal truths nowadays: there are too many antidotes.

Strong hope is a much greater stimulant of life than any single realised joy could be.
