But how can the soul's irascible-part[36] be at one time courageous,
and at the other cowardly? When it is cowardly, it does not consider
reason, or considers reason as having already become evil; or because
the deficiency of its instruments, that is, the lack of weakness of its
organs, hinders it from acting, or feeling emotion, or being irritated.
In the contrary condition it is courageous. In either case, the soul
undergoes no alteration, nor is affected.
