Various people have told me that they have found my course handouts useful. Since Notre Dame is deprecating the web space where many have been hosted in the past, I thought that it might be useful for some to have them here. Feel free to use them as you would like.

But, N.B.: these are just course handouts, many written in an afternoon. The level of care in citing relevant sources and covering all relevant points of view is not what one should expect from a published paper. They were written with the aim of explaining material to a (usually undergraduate) class. Many of them are also now quite old and so (obviously) do not take account of literature which postdates the class. Also, I have changed my mind about some things over the years and regard some past handouts with something approaching horror. So, use at your own risk!
