Regarding equality and justice--just when I thought I was making progress, I find that I need to find the basis for making a return or requital--the precept to make a return or requital when one receives a benefit seems to be more than just the precept to love others, no? But does Aquinas explicitly discuss how the former is derived from the latter?
Just when I thought I had gone as far as I needed, something pops up that I had not considered before. While this may be good philosophically, it's not so good for getting a dissertation done as soon as possible...
