‘Douceur: from sweetness to delight to pleasure to slowness to softness to mildness to languor to tenderness to civility to smoothness. It is useless to try to circumscribe what, at different times, for different people, that word contained . . . History after the French Revolution is the history of progress devoid of the patina of douceur . . . After the Revolution, progress forgets sweetness . . . When the very memory of sweetness is eliminated, when all history becomes son et lumière and no longer cohabitation with protective shadows, then certain well-meaning expressions begin to appear (“leisure time,” “quality of life”), just as people began to talk about “landscape” after nature had already been disfigured . . . Douceur is the patina that is spread over life, that makes it liveable—the dust on the butterfly’s wings. Producing it requires slow, careful alchemy, long simmering, a gentle heat. But this is nonetheless a fire, which ultimately seeks to kill.’

And yet ‘patine’ generally refers to a glaze of sorts. a sheen placed over the object which is not intrinsic to the thing itself. It strikes me as sweetness and civility may be described as a patina but that tenderness or slowness can only exist as inherent qualities..
Thank you, that is beautiful.
