Each state of the human mind has some parable in the physical creation by which it is shadowed forth; nor is it only artists and poets, but even the most abstract thinkers that have drawn from this source. Lively activity we name fire; time is a stream that rolls on, sweeping all before it; eternity is a circle; a mystery is hid in midnight gloom, and truth dwells in the sun. Nay, I begin to believe that even the future destiny of the human race is prefigured in the dark oracular utterances of bodily creation.
