The whole symbolism and ritual of the Blue Lodge in Masonry is, from beginning to end, _a symbol of the journey of the human soul on this earth_, from darkness to light; from sin to righteousness; from ignorance to wisdom and understanding. In other words, it is an exact _theorem_ and solution of the _Magnum Opus_; a symbol of the philosophy and accomplishment of the GREAT WORK. The science and the theology of the present day have been briefly contrasted. Neither of them pretends to give us any real science of the human soul. Science says frankly she "does not know." Theology bids us believe and obey; trust and hope. Philosophy speculates and reasons, while amusing itself with the kaleidoscope of "postulates" and "categories." Science must deal with facts, demonstrate their actuality, and classify them; that is, find their natural order and sequence. In psychology, the facts are _within_ the realm of consciousness, and therefore their demonstration is a matter of individual experience. This is why psychology differs from all other sciences. No one can transfer his individual experiences directly to another. He can describe how he gained them, and give the result and conclusions, and here is where those who know nothing of the real problem, are often both incredulous and contemptuous. The only answer to these is, "they are joined to their idols, let them alone." "They would not believe though one arose from the dead," and yet we are told again and again that the "School of Natural Science" is the "school of personal experience." It may be well to reflect a moment, and ask ourselves, how it is that we really know anything? Is it not through personal experience? Real knowledge comes, and can come, in no other way. No teacher of the real science of psychology can ever transmit or transfer his knowledge to another. All he can do is to describe the methods, and steps, by which he acquired it, and assist the student in acquiring it for himself in the same way, or under the same processes and laws. We have only to reflect on the ordinary experiences of life, to realize that this is a universal principle and rule. In the deeper science of the soul, and the higher life, instead of this law being relaxed, it becomes all the more binding. Do not the principles that adhere in atom, molecule and mass, still hold in worlds and solar systems? Is not this precisely what is meant by "The Reign of Law"? If man were built upon some other scheme or plan than the rest of nature, how could he apprehend or adjust himself to Nature? The very _concept_ of miracle is _lawlessness_, and mystery is but another name for _ignorance_. Knowledge means experience and apprehension of Law. Neither can the laws of Nature and the laws of God be at cross-purposes, for that would make harmony impossible and inconceivable. The confusion and discord are all in us, and the Great Work means adjustment, harmony, and then Knowledge.
