Aristotle

Aristotle analyzed virtues into moral and intellectual virtues (dianoetic virtues, the Greek aretai dianoetikai). In the Posterior Analytics and Nicomachean Ethics he identified five intellectual virtues - as the five ways the soul arrives at truth by affirmation or denial. He grouped them into three classes:

• Theoretical:
  • Sophia -i.e. wisdom of the eternal and unchangeable, philosophical wisdom.
  • Episteme -i.e. scientific knowledge, empirical knowledge.
  • Nous -i.e. intuitive understanding.
• Practical:
  • Phronesis -i.e. practical wisdom/prudence.
• Productive:
  • Techne -i.e. craft knowledge, art, skill.

Subjecent intellectual virtues in Aristotle:

• Euboulia. Deliberating well, deliberative excellence. Thinking properly about the right end.
• Sunesis. Understanding, sagacity, consciousness of why something is as it is. - e.g the understanding you have of why a situation is as it is, prior to having phronesis - understanding of what to do about it -i.e what is the best action.
• Gnomê. Judgement and consideration. Virtue which allows people to make equitable or fair decisions.
• Deinotes. Cleverness. The ability to carry out actions so as to achieve a goal.
