All literature, all philosophical treatises, all the voices of antiquity are full of examples for imitation, which would all lie unseen in darkness without the light of literature.
The poet presents the imagination with images from life and human characters and situations, sets them all in motion and leaves itto the beholder to let these images take his thoughts as far as his mental powers will permit. This is why he is able to engage men of the most differing capabilities, indeed fools and sages together. The philosopher, on the other hand, presents not life itself but the finished thoughts which he has abstracted from it and then demands that the reader should think precisely as, and precisely as far as, he himself thinks. That is why his public is so small.
We come to recognize that playfulness, as a philosophical stance, can be very serious indeed; and moreover, that it possesses an unfailing capacity to arouse ridicule and hostility in those among us who crave certainty, reverence, and restraint.
A philosophical attempt to work out a universal history according to a natural plan directed to achieving the civic union of the human race must be regarded as possible and, indeed, as contributing to this end of Nature.
