The states by virtue of which the soul possesses truth by way of affirmation or denial are five in number, i.e. art, scientific knowledge, practical wisdom, philosophic wisdom, intuitive reason. The soul seeks truth via art , scientific knowledge , practical wisdom , philosophic wisdom , intuitive reason . Practical wisdom is a true and reasoned state of capacity to act with regard to the things that are good or bad for man. Practical wisdom, then, must be a reasoned and true state of capacity to act with regard to human goods. Plainly, then, practical wisdom is a virtue and not an art.
Practical wisdom is a virtue .
It follows that the first principles of scientific truths cannot be grasped either by by science or by art or by prudence. Nor are these first principles the objects of philosophic wisdom. First principles are products of intuitive reason . Wisdom must plainly be the most finished of the forms of knowledge. It follows that the wise man must not only know what follows from the first principles, but must also possess truth about the first principles.
