We can never, even by the strictest examination, get completely behind the secret springs of action. - Immanuel Kant

Science is organized knowledge. Wisdom is organized life.

Phenomena of the external sense are examined and set forth in physics; those of the internal sense in empirical psychology. Pure mathematics considers space in geometry and time in pure mechanics. To these is to be added a certain concept, intellectual to be sure in itself, but whose becoming actual in the concrete requires the auxiliary notions of time and space in the successive addition and simultaneous juxtaposition of separate units, which is the concept of number treated in arithmetic.

...happiness is not an ideal of reason but of imagination, resting solely on empirical grounds.
