The Philosophy of Freedom
Steiner's most Important philosophical work deals both with epistemology, the study of how man knows himself and the world, and with the issue of human freedom. In the first half of the book Steiner focuses on the activity of thinking in order to demonstrate the true nature of knowledge. There he shows the fallacy of the contemporary idea of thinking, pointing out that the prevailing belief in the limits to knowledge is a self-imposed limit that contradicts its own claim to truth. The possibility for freedom is taken up in the second half of the book. The Issue is not political freedom, but something more subtle; freedom of the will. There are those who maintain that man's thoughts and actions are Just as determined as a chemical reaction or a honey bee's behavior. Steiner points again to the activity of thinking, from which arises the possibility of free human action.
