Do you agree with Aristotle that "Virtue is the constitutive good for our happy or flourishing life?"

Yes.

Most of the recent burgeoning interest in the virtues, within philosophy and the social sciences, has been on the role of the virtues in good character and how to cultivate it. However, what is sometimes overlooked is that, historically (for example within Aristotelian approaches), the virtues are seen to be part and parcel of the flourishing life. Flourishing is a wider concept that simply that of good character, and in many ways more complex, politically charged and multi-layered. Terminological disputes abound, for instance, about the relationship between the concepts of ‘well-being’, ‘happiness’ and ‘flourishing’. Even for those who adopt the Aristotelian position of understanding flourishing (eudaimonia) as objective well-being, various theoretical and practical quandaries remain.
