What a relief

"the nature of virtue does not require that man should reach [(attingat)] the mean of right reason as though it were an indivisible point, as the Stoics thought, but it is enough that he should approach [(propre . . . esse, that he be near)] the mean, as stated in the Ethics [(II.9 (1109b18))]." 

"Non enim exigitur ad rationem virtutis, quod attingat rectae rationis medium in indivisibili, sicut Stoici putabant, sed sufficit prope medium esse, ut in II Ethic. dicitur."
