1. It is Science
The Philosophy Of Freedom is not philosophy as such, but rather a description of Rudolf Steiner's experiences on the way to freedom. It does not give a definition of freedom that we merely memorize, but points to a place where freedom originates --the conceptual realm of universal concepts-- where free thinking, pure and unbiased, can be experienced.
“What I was really trying to do in The Philosophy of Freedom, was to locate freedom empirically, and thus put it on a solidly scientific basis.”
2. It is Freedom
Moral freedom is achieved when we bridge the gap between our perceptible unfree nature (built up by nature, society and religion) and the concept of free individuality (ethical individualism) through the course of one's development with the expression of our ideals in life. To become a free individuality we need to have a clear understanding of what free individuality is. POF 9-11
True freedom is only achieved when knowledge and morality are united. (morality informed by knowledge) POF 10-1918 Addition
3. It is Thought Training
The book is intentionally composed in a certain way to broaden and deepen the readers thinking. Each chapter expresses a variety of views leaving the reader free to arrive at their own conclusions. It is independent thinking so we cannot rely on familiar terms and images but must instead make an effort to “intuitively” grasp the universal concepts pointed to by the words. This training in the realm of universal thought is the thought training required to attain freedom.
“The primary purpose of my book is to serve as thought training, training in the sense that the special way of both thinking and entertaining these thoughts is such as to bring the soul life of the reader into motion in somewhat the way that gymnasts exercise their limbs.”
“A personal God is nothing but a human being transplanted into a Beyond.”
5. It is not Anthroposophy
Near the end of his life, Steiner suggested that The Philosophy of Freedom would outlive all his other works. It stands on its own completely independent of his later spiritual research and organizations,
“You will find nothing at all in The Philosophy of Freedom that is derived from clairvoyant communications of spiritual science.”
“this book occupies a position completely independent of my writings on actual spiritual scientific matters... What I have said in this book may be acceptable even to some who, for reasons of their own, refuse to have anything to do with the results of my researches into the spiritual realm.” POF, 1918 Preface to the Revised Edition
