This reminds me of a fine passage in a Spanish poet, which I cannot refrain from quoting: "To live is to dream; experience teaches that man dreams what he is till the moment of awakening. The king dreams that he is a king and passes his days in the error, giving orders and disposing of life and property. The rich man dreams the wealth that is the cause of his anxiety; the poor man dreams the poverty and need from which he suffers. I too dream that I am here laden with chains, and in by-gone days I dreamt that I was happy. Our dreams are but dreams within a dream." So our world may be compared with the cave of which Plato speaks in the Seventh Book of the _Republic_. In the conversation between Dr Hodgson and George Pelham, when George Pelham promised that if he were the first to die and if he found that he had another life he would do all that he could to prove its existence, they referred to the old Platonic myth. In the communications of the so-called George Pelham allusion was made to the allegory, and that justifies me in briefly recalling it. Plato imagines prisoners who from their birth have been enchained in a dark cave in such a way that they are not able either to move or to turn their heads, and can only look straight in front of them. Behind and above the captives a great fire burns, and between the fire and the captives men pass to and fro carrying in their hands vessels, statues, images of animals and plants, and many other objects. The shadows of these men and of the objects that they carry are thrown upon that wall of the cavern which is opposite to the captives, who thus know nothing of the external world but these shadows which they take to be realities, and they spend their time discussing the shadows, naming them and classifying them. One of the captives is carried off from the gloomy place and transported into the external world. At first the light dazzles him and he can distinguish nothing. But by degrees, as time goes on, his sight adapts itself to its surroundings and he learns to look upon the stars and moon, and the sun itself. When he has been brought back into the cave and again sits beside his companions, he takes part in their discussions and tries to make them understand that what they take for realities are only shadows. But they, confident in the results of their lengthy reflections on the subject, laugh him to scorn. The same thing would happen to a soul which had dwelt for a time in the world of spirit and had been brought back into the world of matter.
