For anyone who's interested (and to bookmark for my own future reference ) I found an interesting YouTube channel that covers Aquinas' arguments as well as some criticisms of them. It's evidently the course material for A-Level Religious Studies (where for context, A-Levels are UK education usually for 16-18 year olds, after secondary school, usually prior to going to university). The channel is called "The Cogito", and I've watched several of the videos now and IMO they are very clearly explained and unpacked/dissected. So I'll just list, as links, the relevant videos here:
Aquinas' First Cosmological Argument (The First Way)
Aquinas' Second Cosmological Argument (The Second Way)
Aquinas' Third Cosmological Argument (The Third Way)
Criticisms of the Cosmological Argument
Note: It does not appear have a video for the Fourth Way.
Aquinas' Design Argument (The Fifth Way)
Hume's criticisms of the Design Arguments. Note: This last one also covers Paley's Design Argument, for which there is a separate video for anyone interested, but that's not really relevant to this discussion.
