It was great to see all of you out today. We talked about a couple of things. First, we talked about the way in which the Early Modern picture of science, which is about predicting and controlling the world, seems inevitably to raise questions of ethics. After all, if you're going to control the world, you have to figure out the right way to control it.
After that we discussed Hume's problem of induction - this is to set us up for next week. If we can't see how causes necessitate their effects, then it seems impossible to ground our inductive, or experimental reasoning. Experimental, or inductive reasoning cannot ground itself. We are trying to establish whether the future will resemble the past, so it is no use insisting that it always has. On the other hand, if the past doesn't necessitate the future, we can't get certainty through logic. Bad news for science, it would seem!
Karl Popper will show us a way in which science might work around Hume's puzzle.
