I imagine this has been done to death on this sub-forum, but bear with me for a few.
I (a physics PhD candidate) have been debating with another graduate student (also in physics) about the nature/origin or morality. I, being Catholic, adhere to Absolutism while my classmate adheres to Relativism.
As a proof for absolutism, I stated (using Kreeft’s Refuation… as a guide) that because we have a structure for moral arguments we require a higher level for morality (that is, we require an absolute morality) because otherwise we’d be saying “Blue is a better color than green!” when we say, “Abortion is bad!” His response was,
He gave two more examples, but they had the same form as above. It seems to me, at first, that he’s agreeing with me (that a higher level needs to be there to have an argument) but is disagreeing with the semantics. Then it seems that he doesn’t understand the difference between a principle and a situation (as Kreeft uses the terms) as all three of his examples start with situations and have no principles.
So is there any help to bust his ‘logic’ and help my case?
