All contemporary philosophical material that is useful outside the academy will form the content of this book; this content is presented in the order in which that material must reveal itself to the less educated mind.Those deeper arguments against artificial intellectual objections and extravagances, that which is only the basis of other positive sciences, and finally, that which belongs only to pedagogy in the broad sense, that is, to deliberate and conscious Things of human education will remain outside the scope of this book.Those objections are beyond the reach of a plain intellect; positive science is relinquished to professional scholars, and human education, so far as it is artificially transferred, is relinquished to appointed nationals. Teachers and civil officials did it.

Therefore, this book is not written for professional philosophers, and professional philosophers will find nothing in this book, which does not seem to have been suggested in other works by the same author.This book should be accessible to all readers who can read books in general.Those who simply want to repeat in a slightly altered order long-remembered expressions, and regard this act of remembering as an act of comprehension, will no doubt find this book incomprehensible. This book should fascinate and inspire the reader, and lead him with force from the perceptual world to the supersensible;If, when the work is done with difficulty, the zeal with which men at first chose their ends tends to disappear, so, after the work has been done, men are in direct danger of being wronged in the matter. .In short, the achievement of the author's purpose can only be judged by the effect of the book on the readers for whom it is written, and the author has no say in this matter.

I should also remind—certainly to a few people—that the me described in the book is by no means the author; , and during the period of existence, he can actually talk to himself, think over and over again, draw conclusions, make up his mind like the representative figure imagined by the author in the book, and rely on his own work and thinking to develop purely from himself. And to establish in himself such a way of thinking, the simple concept of which has been given to him in this book.
