"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 gymnastics exercise their limbs." "It expected the reader, as they read, to undergo the sort of inner experience that, in an external sense, is really like waking up out of sleep in the morning." Rudolf Steiner

Research confirms what long-time readers of The Philosophy of Freedom have always known: study of Rudolf Steiner’s book increases the creativity, clarity and depth of one’s thinking. Researchers recruited people who complained of having mental fatigue and an over abundance of superficial thoughts. They divided the volunteers into three groups:
group 1 studied The Philosophy of Freedom 30 minutes at a high intensity 3 times a week
group 2 studied 30 minutes at a moderate intensity 3 times a week
group 3 did... nothing
The results were a 165% increase in cognitive capacity for the intense study group, 125% increase in the moderate study group and the control group who did nothing declined somewhat. The conclusion is that the mind needs regular exercise just as the body or it becomes part of the modern cultural phenomena commonly known as “dumbing down.”

Freedom is action out of one's inner being. Only he may act out of his inner being who draws his motives from the eternal. Rudolf Steiner; Theosophy [1], Chapter IV, The Path of Knowledge
