1. Aristotle on eudaimonia, and function and virtue

2. The good ‘What is the good for human beings?’
What is it that we are aiming at?
What would provide a successful, fulfilling, good life?
Good: the purpose for which we do things, the point of doing them
Some activities (making drugs, diagnosis) are done for the sake of others (health)
Is there some end for whose sake we do everything else?

3. Eudaimonia The good for a human life Eudamonia v happiness ‘Happiness’
‘living well and faring well’: flourishing
Eudamonia v happiness
Eudaimonia is not a state of mind, but relates to the activity of living
It is not subjective, but objective
It is not easily changed, but relates to a life as a whole

4. What is eudaimonia?
Not pleasure: animals share in this, but there is more to a human life
Not wealth: money is a means to an end
Honour? But what do you want to be honoured for?
The virtues? Not just having them, but exercising them. What about being virtuous but very unfortunate?

5. Final ends
Final end: an end that we desire for its own sake, not for some further purpose
Is there just one ‘final end’? Is eudaimonia or anything else our only good?
Some final ends, e.g. pleasure, knowledge, we seek both for their own sake and for the sake of something else, viz. eudaimonia
These other final ends are constituent parts of eudaimonia
But only eudaimonia we seek for its own sake and no other purpose

6. Eudaimonia and function
Eudaimonia: living well, our final end
But what is this?
Ergon: something’s function or characteristic form of activity (functioning rather than purpose)
An x is a good x when it performs its characteristic activity well
Good eyes see well; good knives cut well; good plants flourish
(c) Michael Lacewing

7. Virtue Arête: a quality that aids the fulfilment of a thing’s ergon
An excellence or ‘virtue’
The focus of an eye; the sharpness of a knife
(c) Michael Lacewing

8. The ‘function argument’
Being rational – guided by reasons – is the characteristic activity of human beings
Not reasoning but doing things for reasons
This is a psychological property, an activity of the ‘soul’ (psyche)
So our virtues will be properties than enable us to do this well
So eudaimonia consists in activity of the soul which exhibits the virtues by being in accordance with (‘good’ or ‘right’) reason (orthos logos)
(c) Michael Lacewing

9. Testing the analysis Is this argument plausible?
There are three types of good:
goods of the mind (e.g. intelligence, courage, etc.)
goods of the body (e.g. strength, health etc.)
‘external’ goods (e.g. wealth, food, etc.).
People generally agree that the goods of the mind are worth more than the others.
Eudaimonia is ‘living well’. The argument spells this out.
(c) Michael Lacewing

10. Testing the analysis
The good life involves virtue, pleasure and prosperity
Virtue: Central to the account. We must act on virtue, not merely possess it.
Pleasure: People find pleasant whatever it is that they love. A virtuous person loves living virtuously.
Prosperity: In order to live virtuously, we will also need a certain amount of external goods.
