Reflect on your present blessings, of which every man has many, not on your past misfortunes, of which all men have some. The chief function of the body is to carry the brain around. X is work. Y is play. Z is keep your mouth shut.
Imagination is more important than knowledge.
Things should be made as simple as possible, but not any simpler. Few are those who see with their own eyes and feel with their own hearts. If the possibility of the spiritual development of all individuals is to be secured, a second kind of outward freedom is necessary. The development of science and of the creative activities of the spirit in general requires still another kind of freedom, which may be characterised as inward freedom. It is this freedom of the spirit which consists in the interdependence of thought from the restrictions of authoritarian and social prejudices as well as from unphilosophical routinizing and habit in general.
