Uxor tua sicut vitis abundans, in lateribus domus tuae

Pretiosa in conspectu Domini mors sanctorum eius

I am presently embarked on the admittedly foolhardy project of translating the whole of the Summa Theologiae. Will I ever finish? Well, at least I have started.  As I fashion the latest drafts of the various questions, I make them available here in .pdf format.  I am constantly making unannounced revisions to these files.  But the latest versions are those available here on any given day.

Part 1 and Part 1-2 and Part 2-2 are complete in a loose sense.  
That is to say, I'm constantly revising them as I have occasion to re-read them.  A slightly earlier version of the Treatise on Law (Part 1-2, questions 90-108) came out in book form in 2009 from St. Augustine's Press (click here for the Amazon site). Likewise, a slightly earlier version of The Treatise on Human Nature (Part 1, questions 75-102) came out in book form in 2010 from St. Augustine's Press (click here for the Amazon site).

Comments are welcome, no matter what their nature.  At present I am especially interested in receiving corrections to the treatises in Part 2-2 from the treatise of prudence on. (Experts on religious life are especially invited to look at ST 2-2, qq. 184-189). I have already incorporated the truly amazing number of corrections that I have received to this point. I am grateful to all of you who have sent corrections, especially to a couple of people who have gone way beyond anything I could have dreamt of or hoped for.

And so it's on to Part 3! Just 90 more questions.
