Preface to the Revised Edition, 1918

These were my thoughts about the content of this book when I wrote it twenty-five years ago. To-day, again I must write similarly if I am to characterize the aim of this book. In the first edition I limited myself to saying no more than was in the strictest sense connected with the two fundamental problems described above. If anyone should be surprised at not finding in this book as yet, any reference to that region of the world of spiritual experience described in my later writings, then he must consider that at that time it was not my purpose to describe results of spiritual research, but first to lay the foundation on which such results can rest. This “Philosophy of Freedom” does not contain any special results of this kind, any more than it contains special results of the natural sciences. But what it contains cannot, in my view, be dispensed with by anyone who strives for certainty in such knowledge. What I have said in this book can also be acceptable to many who, for reasons of their own, will have nothing to do with the results of my spiritual scientific research. But one who can regard these results of spiritual scientific research as something to which he is drawn, will recognize as important what is attempted here. It is this: to prove that an open-minded consideration of just the two problems I have indicated, problems which are fundamental to all knowledge, leads to recognition of the fact that man is living within the reality of a spiritual world. In this book the attempt is made to justify knowledge of the realm of spirit before entering upon spiritual experience. And this justification is undertaken in such a way that, for anyone able and willing to enter into this discussion, there is no need, in order to accept what is said here, to cast furtive glances at the experiences which my later writings have shown to be relevant.
