What I have here endeavored to do, merely in outline, is to show that certain modern beliefs, dogmas, and creeds, which have been carried over and have survived from a far less enlightened age or period, can no longer be valid in the light of our modern knowledge. But, further than that, I shall hope to indicate that even in the remotest past there was already a deeper knowledge, a real Gnosis which we are in fact only now beginning to recover. It is that ancient Gnosis which must be the Religion of the Future; for, as I shall hope to show to some extent, all our scientific discoveries and our modern philosophical thinking tends to confirmation and restatement of it.
