“Espousing the melancholy of ancient symbols, I would have freed myself.”

Context: The Sun is the ancient symbol of the life-giving and generative power of the Deity. To the ancients, light was the cause of life; and God was the source from which all light flowed; the essence of Light, the Invisible Fire, developed as Flame manifested as light and splendor. The Sun was his manifestation and visible image; and the Sabæans worshipping the Light — God, seemed to worship the Sun, in whom they saw the manifestation of the Deity.
The Moon was the symbol of the passive capacity of nature to produce, the female, of which the life-giving power and energy was the male. It was the symbol of Isis, Astarte, and Artemis, or Diana. The "Master of Life" was the Supreme Deity, above both, and manifested through both; Zeus, the Son of Saturn, become King of the Gods; Horus, son of Osiris and Isis, become the Master of Life; Dionusos or Bacchus, like Mithras, become the author of Light and Life and Truth.

Context: It is astonishingly beautiful and interesting, how thought is absent when you have an insight. Thought cannot have an insight. It is only when the mind is not operating mechanically in the structure of thought that you have an insight. Having had an insight, thought draws a conclusion from that insight. And then thought acts and thought is mechanical. So I have to find out whether having an insight into myself, which means into the world, and not drawing a conclusion from it is possible. If I draw a conclusion, I act on an idea, on an image, on a symbol, which is the structure of thought, and so I am constantly preventing myself from having insight, from understanding things as they are.

Context: Science has its nights and its dawns, because it gives the intellectual world a life which has its regulated movements and its progressive phases. It is with Truths, as with the luminous rays: nothing of what is concealed is lost; but also, nothing of what is discovered is absolutely new. God has been pleased to give to Science, which is the reflection of His Glory, the Seal of His Eternity.
It is not in the books of the Philosophers, but in the religious symbolism of the Ancients, that we must look for the footprints of Science, and re-discover the Mysteries of Knowledge.

"The Future of Democracy"
What I Saw in America (1922)
Context: There is truth in every ancient fable, and there is here even something of it in the fancy that finds the symbol of the Republic in the bird that bore the bolts of Jove. Owls and bats may wander where they will in darkness, and for them as for the sceptics the universe may have no centre; kites and vultures may linger as they like over carrion, and for them as for the plutocrats existence may have no origin and no end; but it was far back in the land of legends, where instincts find their true images, that the cry went forth that freedom is an eagle, whose glory is gazing at the sun.
