Lecture VIII
In a sense, the book is only a kind of musical score that one must read with inner thought activity in order to progress, as the result of one's own efforts, from one thought to the next. The book constantly presupposes the mental collaboration of the reader. Moreover, the book presupposes that which the soul becomes in the process of such mental exertion. Anyone who has really worked through this book with his own inner thinking activity and cannot confess that he has come to know himself in a part of his inner life in which he had not known himself previously has not read Philosophy of Freedom properly. One should feel that one is being lifted out of one's usual thinking [ Vorstellen] into a thinking independent of the senses [ ein sinnlichkeitsfreies Denken], in which one is fully immersed, so that one feels free of the conditions of physical existence. Whoever cannot confess this to himself has actually misunderstood the book. One should be able to say to oneself: now I know, as a result of the inner thought activity I myself have expended, what pure thinking actually is.
