[Greek]: nor reared in pure sunlight but in mingled shade. Plato, Phaedrus, 239c. The passage describes the selfishness of a lover restricting, for his own advantage and power of control, the loved one's progress towards a self-sufficient manliness. Ruskin also employs it when describing twilight in the paintings of Sir. L. Alma-Tadema in The Art of England. There is perhaps an allusion to Plato 's view outlined in The Republic of the world as a place of appearances remotely related to more substantial and unchanging forms just as shadows are only a dim reflection of objects which, in turn, depend on light in order to be apprehended.
