IV. That the man of Perfected Self-Mastery unites the qualities of Self-Control and Endurance, and some say that every one who unites these is a man of Perfect Self-Mastery, others do not.
V. Some confound the two characters of the man who has no Self-Control, and the man of Imperfect Self-Control, while others distinguish between them.
VI. It is sometimes said that the man of Practical Wisdom cannot be a man of Imperfect Self-Control, sometimes that men who are Practically Wise and Clever are of Imperfect Self-Control.
VII. Again, men are said to be of Imperfect Self-Control, not simply but with the addition of the thing wherein, as in respect of anger, of honour, and gain.
These then are pretty well the common statements.
Chapter II.
Now a man may raise a question as to the nature of the right conception in violation of which a man fails of Self-Control.
That he can so fail when knowing in the strict sense what is right some say is impossible: for it is a strange thing, as Socrates thought, that while Knowledge is present in his mind something else should master him and drag him about like a slave. Socrates in fact contended generally against the theory, maintaining there is no such state as that of Imperfect Self-Control, for that no one acts contrary to what is best conceiving it to be best but by reason of ignorance what is best.
With all due respect to Socrates, his account of the matter is at variance with plain facts, and we must enquire with respect to the affection, if it be caused by ignorance what is the nature of the ignorance: for that the man so failing does not suppose his acts to be right before he is under the influence of passion is quite plain.[[2]]
There are people who partly agree with Socrates and partly not: that nothing can be stronger than Knowledge they agree, but that no man acts in contravention of his conviction of what is better they do not agree; and so they say that it is not Knowledge, but only Opinion, which the man in question has and yet yields to the instigation of his pleasures.
