An Outline of Occult Science

An Outline of Occult Science

Human understanding, as it works in everyday life and in ordinary science, is actually so constituted that it cannot penetrate into superphysical worlds. 

This may be proven beyond the possibility of denial. But this proof can have no more value for a certain kind of soul-life than the proof one would use in showing that man's natural eye cannot, with its visual faculty, penetrate to the smallest cells of a living being, or to the constitution of far-off celestial bodies.

A book of this kind is bound to proffer views to which any person may attain, and these views must be presented in such a way as to suggest no shade of the personal element, that is, as far as such a thing is possible.
It is therefore not in this sense that the personal note is sounded. It is only intended to explain how it was possible for the author to understand the above characterized opinions concerning his presentations, and yet was able to write this book.
It is true there is one method which would have made the introduction of the personal element unnecessary--this would have been to specify in detail all those particulars which would show that the statements here made are in agreement with the progress of modern science.
