Note 6 — Chapter XIV · SIN AND WEAKNESS.
Reading edition
This view is summed up in the phrase that ‘the perturbations are κακά, but not κακίαι’ (Stob. ii 7, 5 b), which accords with the principle that only vice and what is akin to vice is evil. The Roman writers realized the difficulty in the use of words: ‘morbi autem et aegrotationes partes sunt vitiositatis; sed perturbationes sintne eiusdem partes quaestio est. vitia enim adfectiones sunt manentes, perturbationes autem moventes, ut non possint adfectionum manentium partes esse’ Cic. Tusc. disp. iv 13, 29 and 30.
