Sto-lĭd'i-ty, n.

[Lat. stoliditas, Fr. stolidité, It. stolidità, stolidezza, Sp. estolidez.] The state or quality of being stolid; dullness of intellect; stupidity.

These certainly are the fools in the text, indocile, intractable fools, whose stolidity can baffle all arguments, and be proof against demonstration itself. Bentley.
