An announcement: next week's class will end early, around 7:25 PM.
Today we discussed Ian Hacking's argument for entity realism. Hacking proposed that the strongest case for realism is made by scientists who do not theorize, but interact with and manipulate objects. It is doing things with entities, not theorizing about them, that shows their existence. Hacking's argument parallels arguments often made for basic, common-sense knowledge of an external world: we know there is an external world because we are embodied in it.
We then refreshed our memory regarding virtue ethics. Aristotle, as we saw, understands a life of flourishing as a life lived in awareness of the moral landscape. A person living this way will be an excellent example of a human being. Virtues, as we saw, are character traits that are adjusted so as to be appropriate to the demands made of us by the moral world. A good character is thus like a fit body: both are prepared for whatever the world presents to us.
