0. THE GOAL OF KNOWLEDGE
0.0 Cult Of Individuality
 I believe I am right in pointing out one of the fundamental characteristics of our age when I say that, at the present day, all human interests tend to center in the cult of individuality. An energetic effort is being made to shake off every kind of authority. Nothing is accepted as valid, unless it springs from the roots of individuality. Everything that hinders the individual from fully developing his powers is thrust aside. The saying “Each one of us must choose his hero in whose footsteps he toils up to Mount Olympus” no longer holds true for us. We allow no ideals to be forced upon us. We are convinced that in each of us, if only we probe deep enough into the very heart of our being, there dwells something noble, something worthy of development. We no longer believe there is a norm of human life to which we must all strive to conform. We regard the perfection of the whole as depending on the unique perfection of each single individual. We do not want to do what anyone else can do equally well. No, our contribution to the development of the world, however trifling, must be something that, by reason of the uniqueness of our nature, we alone can offer. Never have artists been less concerned about rules and norms in art than today. Each one asserts the right to express in the creations of his art what is unique in him, just as there are playwrights who write in dialect rather than conform to the standard diction grammar demands
 No better expression for these phenomena can be found than this, they result from the individual’s striving for freedom, developed to its highest pitch. We do not want to be dependent in any respect, and where dependence must be, we tolerate it only on condition it coincides with a vital interest of our individuality.
0.1 Path Of Inner Truth
 Truth, too, will be sought in our age only in the depths of human nature. Of the following two well-known paths described by Schiller, it is the second that will today be found most useful:
We both seek truth; you in outer life,
I in the heart within. Each of us are sure to find it.
The healthy eye can track the Creator in the outer world;
The healthy heart mirrors the world within.
Truth that comes to us from the outside always brings with it uncertainty. We are only convinced by what appears to each of us inwardly as truth.
0.2 Empowered By Truth
 Only truth can give us assurance in developing our individual powers. Whoever is tormented by doubts finds his powers weakened. If baffled by a world full of riddles he can not find a goal for his creative activity.
0.3 Inner Knowing
 We no longer want to believe; we want to know. Belief demands the acceptance of truths without having the insight to wholly comprehend. What is not clearly understood goes against our individuality that wants to experience everything in the depths of its inner core. The only knowing that satisfies us is the kind that submits to no external norm, but springs from the inner life of the personality.
0.4 Advance In Knowledge
 Nor do we want the kind of knowledge that has been encased in rigid academic rules, and stored away as valid for all time. Each of us claims the right to start from the facts we know, from our own direct experience, and from there advance to knowledge of the whole universe. We strive for certainty in knowledge, but each in his own way.
0.5 Recognition Of Truth
 Nor should the teachings of science be presented in a way to imply that its acceptance is compulsory. None of us would give a scientific work a title like Fichte once did: “A Crystal Clear Report to the General Public on the Actual Nature of the Latest Philosophy, An Attempt to Compel the Reader to Understand.” Today, no one should be compelled to understand. We expect neither recognition or agreement from anyone unless through his own insight he recognizes the truth of what is proposed. We do not want to cram facts of knowledge into even an immature person, a child. We try to develop the child's capacities in such a way that his understanding arises from within and compulsion becomes unnecessary.
0.6 Apply Freedom Principles
 I have no illusions as to the characteristics of the present time. I know how much a stereotypical attitude, lacking all individuality, is prevalent everywhere. Many flaunt a way of life that follows only the current cultural trends. But I also know that many of my contemporaries strive to conduct their lives in the direction of the principles I have suggested. To them I dedicate this book. It does not claim to offer the only possible way to truth, but is meant to describe the path taken by one for whom truth is central.
0.7 Practice Pure Thinking
 At first the reader is lead into abstract regions, where thought must draw sharp outlines to reach clearly defined positions. But the reader is also led from arid concepts into concrete life. I am fully convinced that to experience life in all its aspects, one must soar into the realm of concepts. Whoever is limited to the pleasures of the senses misses the sweetest joys of life.
The oriental sage requires his disciples to live a life of resignation and asceticism for years before he shares with them his knowledge. The West no longer demands pious exercises and ascetic practices to attain knowledge. It does require, however, a sincere willingness to prepare for science by withdrawing oneself awhile from the immediate impressions of life, and entering the realm of pure thought.
0.8 Self-Governing Knowledge (empowered ideas)
 There are many regions of life. A specific field of science develops for each one. But life itself is a unity, and the more the sciences immerse themselves in separate fields, the more they move away from seeing the world as a living whole. It is essential to have a supreme science that seeks in the separate sciences the principles for leading man back to the fullness of life. The aim of the scientific specialist's research is to become aware of the world and gain insight into how it works. The aim of this book is philosophical: science itself is to become a living whole. The various branches of science are preparatory stages on the way to the all-inclusive science intended here.
A similar relationship governs the arts. A composer works on the basis of the theory of composition. This theory is an accumulation of principles of what one needs to know in order to compose music. In composing, the rules of theory serve life, that is, theory serves actual reality.
In the same way philosophy is an art. All genuine philosophers have been artists in the conceptual realm. For them human Ideas become their artistic material and the method of science becomes their artistic technique. Abstract thinking takes on an individual life of its own. Ideas become powerful forces in life. We no longer merely know about things, but have made knowing into a real self-governing organism, ruled by its own laws. Our actual working consciousness has lifted itself above a mere passive reception of truths.
0.9 Science Of Freedom
 The main theme of my book concerns these questions: How philosophy, as an art, relates to freedom; what freedom is; and whether we do, or can, participate in it. Scientific explanations are included because in the end they provide clarification about those questions that are, in my opinion, most important to people. These pages offer a 'Philosophy of Freedom.'
0.10 All-Around Human Development
 All science would be nothing but the satisfaction of idle curiosity if it did not elevate the existential value of human personality. The true value of the sciences is seen only when we are shown the importance of their results for humanity. The ultimate aim of the individuality cannot be the cultivation of only a single capacity. Rather, it must be the development of all the potential that slumbers within us. Knowledge has value only by contributing to the all-around development of the whole of human nature.
0.11 Ideas Serve Human Goals
 This book does not regard the relationship of science to life in such a way that the human being must bow down before the world of Ideas and devote his powers to its service. On the contrary, it shows that he should take possession of the world of Ideas to use them for his human goals. These extend beyond those of mere science.
0.12 Master Of Ideas
 One must confront an Idea as master, or else become its slave.
