But winter fell on these villages, darkness and extreme cold descended on the hillside. There must have been some place indoors where men could retire, both in the depths of winter and in the summer heats, where they could sit and drink, where they could lie stretched at their ease, where they could talk. It is Plato, of course, who reveals the life indoors, and describes how, when a party of friends met and had eaten not at all luxuriously and drunk a little wine, some handsome boy ventured a question, or quoted an opinion, and Socrates took it up, fingered it, turned it round, looked at it this way and that, swiftly stripped it of its inconsistencies and falsities and brought the whole company by degrees to gaze with him at the truth. It is an exhausting process; to contract painfully upon the exact meaning of words; to judge what each admission involves; to follow intently, yet critically, the dwindling and changing of opinion as it hardens and intensifies into truth. Are pleasure and good the same?
