Aristotelian ethics is not just about cultivating virtue as a kind of good character. Although he does emphasize it a lot, ultimately character is just a means and a potentiality for actualization of the real goal of that part of living well that is under our power. The actualization itself comes from good practice (praxis), grounded in sound, well-rounded deliberation and choice. Aristotle also says the very best life is that of the philosopher. Not only is philosophy valuable in itself, but it also helps us deliberate.
The best deliberation and choice is supported by intellectual virtues, a concern for justice, and a spirit of friendship or love, but it would not even get off the ground without progress in the classic “moral” virtues, which are all said to pertain to our emotions or passions, and to how we are affected by pleasure and pain. Aristotle characterizes each of these emotional virtues as a kind of mean, or balanced emotional state.
Thus, courage is presented as a mean between rashness and cowardice. Temperance is a mean between self-indulgence and insensibility. Interestingly, justice and prudence are also included among emotional virtues, and subjected to a similar analysis. Other emotional virtues are presented as following the same pattern. Unlike the Stoics, neither Plato nor Aristotle advocated suppressing the emotions.
