Presumably to say that happiness is the supreme good seems a platitude, and some more distinctive account of it is still required. This might perhaps be achieved by grasping what is the function of man.. Is it likely that whereas joiners and shoemakers have certain functions or activities, man as such has none, but has been left by nature a functionless being?
Aristotle - Happy - Man

Men are good in one way, but bad in many.
Aristotle - Goodness - Bad - Man

The soul is characterised by these capacities: self-nutrition, sensation, thinking and movement.

A likely impossibility is always preferable to an unconvincing possibility.
Aristotle - Impossible - Possible

To say of what is that it is not, or of what is not that it is, is false, while to say of what is that it is, and of what is not that it is not, is true.
Aristotle - Confusing - Truth - Falseness

The origin of action - its effecient, not its final cause - is choice, and that of choice is desire and reasoning with a view to an end. This is why choice cannot exist either without thought and intellect or without a moral state; for good action and its opposite cannot exist without a combination of intellect and character. Intellect itself, however, moves nothing, but only the intellect which aims at an end and is practical.
Aristotle - Action - Choice - Intelligence

The good person is related to his friend as to himself (for his friend is another self).
