Etymologically, the entry records: Widely attributed to British philosopher Jeremy Bentham (1748-1832), but apparently used only by his successors. Root origin matters for spelling because borrowed morphemes (Greek, Latin, Old French, Old English) carry their source-language orthographic conventions into modern English, which is why historical etymology is often the cleanest predictor of whether a cluster like "-ough", "-eau", or "-tion" will appear. For readers arriving here from a spelling check, the authoritative guidance is: the correct English form is felicific calculus, spelled F-E-L-I-C-I-F-I-C- -C-A-L-C-U-L-U-S, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
