Welcome to Tollat Summam. I began this project about two years ago. Due in large part to the learning which resulted from sketching out the expositions contained in this blog, I became aware of the inadequacy of these same expositions. For the most part they are solid attempts at explaining the true sense of St. Thomas's text. However, I have begun to revise and completely rewrite most of the content which was originally posted here. The blog will remain untouched, though the re-written commentary will eventually be published elsewhere (hopefully in print). I hope that what remains here is useful to you, but read it with a skeptical eye.
