This quotation is not known to exist in Plato's writings. It apparently first appeared as a quotation attributed to Plato in The Pleasures of Life, Part II by Sir John Lubbock (Macmillan and Company, London and New York), published in 1889.
Misattributed
This quotation, often attributed on the Internet to Plato, cannot be found in any of Plato's writings, nor can it be found in any published work anywhere until recent years. If it really were a quotation by Plato, then some author in the recorded literature of the last several centuries would have mentioned that quote, but they did not. The sentiment isn't new, however. The ancient Roman Seneca, in his work on "Morals," quoted an earlier Roman writer, Lucretius (who wrote about the year 50 B.C.), as saying "we are as much afraid in the light as children in the dark." (Seneca was paraphrasing a longer passage by Lucretius from De Rerum Natura (On the Nature of Things), Book II, lines 56 et seq.)
