An Outline of Occult Science
By
Rudolf Steiner, Ph.D.
Authorized Translation from the Fourth Edition
In placing a book such as this in the hands of the public, the writer must calmly anticipate every kind of criticism regarding his work which is likely to arise in the present day. A reader, for instance, whose opinions are based upon the results of scientific research, after noting certain statements made here touching these things, may pronounce the following judgment: "It is astounding that such statements should be possible in our time. The most elementary conceptions of natural science are distorted in such a manner as to denote positively inconceivable ignorance of even the rudiments of science. The author uses such terms, for instance, as 'heat' in a way that would lead one to infer that he had let the entire wave of modern thought on the subject of physics sweep past him unperceived. Any one familiar with the mere elements of this science would show him that not even the merest dilettante could have made these statements, and they can only be dismissed as the outcome of rank ignorance."
One who undertakes to represent certain results of scientific spiritual research of the kind recorded in this book, must above all things be prepared to find that this kind of investigation is at the present time almost universally regarded as impossible. For things are related in the following pages about which those who are today esteemed exact thinkers, assert that they will probably remain altogether indeterminable by human intelligence. One who knows and can respect the reasons which prompt many a serious person to assert this impossibility, would fain make the attempt again and again to show what misunderstandings are really at the bottom of the belief that it is not given to human knowledge to penetrate into the superphysical worlds.
