In physics we have outgrown archer and apple-pie definitions of the fundamental symbols. To a request to explain what an electron really is supposed to be we can only answer, "It is part of the A B C of physics". The external world of physics has thus become a world of shadows. In removing our illusions we have removed the substance, for indeed we have seen that substance is one of the greatest of our illusions. Later perhaps we may inquire whether in our zeal to cut out all that is unreal we may not have used the knife too ruthlessly. Perhaps, indeed, reality is a child which cannot survive without its nurse illusion. But if so, that is of little concern to the scientist, who has good and sufficient reasons for pursuing his investigations in the world of shadows and is content to leave to the philosopher the determination of its exact status in regard to reality. In the world of physics we watch a shadowgraph performance of the drama of familiar life. The shadow of my elbow rests on the shadow table as the shadow ink flows over the shadow paper. It is all symbolic, and as a symbol the physicist leaves it. Then comes the alchemist Mind who transmutes the symbols. The sparsely spread nuclei of electric force become a tangible solid; their restless agitation becomes the warmth of summer; the octave of aethereal vibrations becomes a gorgeous rainbow. Nor does the alchemy stop here. In the transmuted world new significances arise which are scarcely to be traced in the world of symbols; so that it becomes a world of beauty and purpose — and, alas, suffering and evil. The frank realisation that physical science is concerned with a world of shadows is one of the most significant of recent advances.

The world that our senses and our consciousness habitually acquaint us with is now nothing more than the shadow of itself; and it is cold like death.

The external world of physics has thus become a world of shadows. In removing our illusions we have removed the substance, for indeed we have seen that substance is one of the greatest of our illusions.

In some way the material universe appears to be passing away like a tale that is told, dissolving into nothingness like a vision.

To sacrifice the moral to the physical, as is done in these days, is to sacrifice reality for a shadow.

Materiality begets oblivion.

When matter is put aside, all creation becomes exclusively mental, that’s all.

Broad views about life have shrunk into religions, and we have been turned into their symbols. They regard us as empty symbols. Symbols of a religion, a nation. We mustn’t be trapped by that. In this war, let that be the ground of your contest. A ground that cannot be reduced to definition and detail.

The physical world is entirely abstract and without actuality apart from its linkage to consciousness.

In religions which have lost their creative spark, the gods eventually become no more than poetic motifs or ornaments for decorating human solitude and walls.

Material existence is entirely founded on a phantom realm of mind, whose nature and geography are unexplored.

The shadow has become the substance.
