Knowledge and action... are only two aspects of one and the same faculty... There are things that intelligence alone is able to seek, but which, by itself, it will never find. These things instinct alone could find; but it will never seek them.
Whoever sets out to persuade men to accept a new idea, or one which seems to be new, not just as an idea, but as a truth that is felt, should know beforehand that the human mind is not a blank sheet, on which one an write with ease, and should not therefore grieve or despair when he finds that people do not pay attention to him.

I live in the world, but I seem to myself not of it!.. Natural phenomena are but the shadows of the spirit form which they spring, as the human face changes under the influence of love, hatred or fear... When, O when, shall I be able to reveal its poetry? I see everywhere and in ever object unceasing motion, and in that motion a creative force forever and forever repeating and re-repeating the same simple process as to infinity. Through all nature the grand rhythms roll and heaven and earth are filled with the melody. Men are but boys chasing shadows. The spiritual significance of the world none seem to see - the infinite simplicity of its process are none care to understand.
