Science and Immortality (1904)
Context: The search of science for the spirits has been neither long nor earnest; nor is it a matter of surprise that it has not been undertaken earlier by men whose training had fitted them for the work.
It is no clear, vasty deep, but a muddy, Acheronian pool in which our modern spirits dwell, with Circe as the presiding deity and the Witch of Endor as her high priestess. Commingling with the solemn incantations of the devotees who throng the banks, one can hear the mocking laughter of Puck and of Ariel, as they play among the sedges and sing the monotonous refrain, "What fools these mortals be!" Sadly besmirched, and more fitted for a sojourn in Ancyra than in Athens, has been the condition of those who have returned from the quest, and we cannot wonder that scientific men have hesitated to stir the pool and risk a touch from Circe's wand. All the more honour to those who have with honest effort striven to pierce the veil and explore the mysteries which lie behind it.

Part III : The Mystic Ruby
The Flower of Old Japan and Other Poems (1907), The Flower of Old Japan
Context: p>Mystery: Time and Tide shall pass,
I am the Wisdom Looking-Glass.This is the Ruby none can touch:
Many have loved it overmuch;
Its fathomless fires flutter and sigh,
Being as images of the flame
That shall make earth and heaven the same
When the fire of the end reddens the sky,
And the world consumes like a burning pall,
Till where there is nothing, there is all.</p
