Sentimental poetry differs from naive poetry in that it relates the real state at which the latter stops to ideas and applies ideas to that reality.
Friedrich SchillerIf you would attain to your highest, go look upon a flower;what the flower does willessly, that do willingly.
Friedrich SchillerEach 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.
