An Outline of Occult Science is fascinating and definitive text on the subject of occult science by Rudolph Steiner. This classic book of the occult contains the following exerpt: 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."
