But nothing which is done and past can be the object of Moral

Choice; for instance, no man chooses to have sacked Troy;

because, in fact, no one ever deliberates about what is past, but

only about that which is future, and which may therefore be

influenced, whereas what has been cannot not have been: and so

Agathon is right in saying

"Of this alone is Deity bereft, To make undone whatever hath been

done."

Thus then Truth is the work of both the Intellectual Parts of the

Soul; those states therefore are the Excellences of each in which

each will best attain truth.

Chapter III.

Commencing then from the point stated above we will now speak of

these Excellences again. Let those faculties whereby the Soul

attains truth in Affirmation or Negation, be assumed to be in

number five:[10] viz. Art, Knowledge, Practical Wisdom, Science,

Intuition: (Supposition and Opinion I do not include, because by

these one may go wrong.)
