This is a fantastic resource on in general - note that Thomas often wrote _better_ objections than those who held the positions he would argue against. That is, he would take the arguments he disagreed with and make them more cogent, more reasonable, and provide more applicable facts and citations than were in popular circulation at the time. Then he would counter these _best_ arguments. The point was to find the truth, not to win the argument. That said, the _Summa_ assumes that you are reasonably familiar with the works of Aristotle and Plato - so some arguments (or counter-arguments) may sound arbitrary to those who are not yet familiar with those works. Final note, another good source to read the Summa is http://newadvent.org/summa/ http://newadvent.org/summa/
