C.S. Lewis responds:
"Are we not our true selves when naked? In a sense, no. The word naked was originally a past participle; the naked man was the man who had undergone the process of naking, that is, of stripping or peeling (you used the verb of nuts and fruit). Time out of mind the naked man has seemed to our ancestors not the natural but the abnormal man; not the man who has abstained from dressing but the man who has been for some reason undressed. And it is a simple fact--anyone can observe it at a men's bathing place--that nudity emphasises common humanity and soft-pedals what is individual. In that way we are 'more ourselves' when clothed." - From The Four Loves, chapter 5
Update:
A friend emailed me wondering about the context for posting the CSL quote. The answer is simple and I probably should have offered an introduction before posting it. I am aware of "back to nature" types both historically and presently who think nakedness desirable, and a step forward toward a kind of stripped-down authenticity. I think the CSL quote addresses that notion insightfully and concisely.
