Quote #10
[...] it would also be reasonable for the gods to delight in what is best and most akin to them—this would be the intellect—and to benefit in return those who cherish this above all and honor it, on the grounds that these latter are caring for what is dear to the gods...And that all these things are available to the wise person especially is not unclear. He is dearest to the gods, therefore, and it is likely that this same person is also happiest. As a result, in this way too, the wise person would be especially happy. (10.8.1179a26-32)
And there you have it: to be wise is to be happy.
More than that, it's to be blessed by the gods. Dang. It's interesting that Aristotle, who's been so interested in establishing what is particular to humans, should discover that the best thing for them is not to be humans but to be gods. Oh, the irony.
But seriously, humanity is, in this philosophy, marked by a kind of divinity not available to animals. That divinity is the intellect, which can perceive itself and grasp the idea of superior ideals and beings.
