Clothes seem to warm a man, not by throwing out heat themselves (for in itself every garment is cold, whence in great heat or in fevers people frequently change and shift them) , but the heat which a man throws out from his own body is retained and wrapped in by a dress fitting close to the body, which does not admit of the heat being dissipated when once it has got firm hold.

Context

“212 "Malim δαιτυμόνας." Wyttenbach, who remarks generally on this short treatise, "Non integra videtur esse nec continua disputatio, sed disputationis, Plutarcheæ tamen, excerptum compendium." ON VIRTUE AND VICE. § i. Clothes seem to warm a man, not by throwing out heat themselves (for in itself every garment is cold, whence in great heat or in fevers people frequently change and shift them) , but the heat which a man throws out from his own body is retained and wrapped in by a dress fitting close to the body, which does not admit of the heat being dissipated when once it has got firm hold. A somewhat similar case is the idea that deceives the mass of mankind, that if they could live in big houses, and get together a quantity of slaves and money, they would have a happy life. But a happy and cheerful life is not from without, on the contrary, a man adds the pleasure and gratification to the things that surround him, his temperament being as it were the source of his feelings.213” source
