''Man defines himself by his deeds - and what kind of image of man do we see in the mirror of our present times?'' The poet and dramatist Friedrich Schiller was also a profound philosopher, who described his work On the Aesthetic Education of Man as ''the best thing that I have done in my life''. This impassioned treatise analyses politics, revolution and human nature to define the relationship between beauty, art and morality. Expressed as a series of letters to a patron, it argues that only an aesthetic education - rather than government reform, religion or moral teachings - can achieve a truly free society, and must be placed at the heart of human experience. One of the most important works of German philosophy, its arguments remain as arresting and inspiring as when they were first written.
