One way

I took a sculpture class as an undergrad (somehow I fit it in between the 18 philosophy courses, not counting the 3 I sat in on and never missed a day).

My professor said that one of his contemporaries had bragged that he had found five ways to represent drapery.  This is no mean task, and my professor said he hadn’t a clue about how to go about representing drapery, let alone know five ways.  But he said, after a while, he found one way to do it.  And one way is all that he really needed.

In philosophy there are untold numbers of bad arguments and reasons why those arguments are bad.  None of them matter, though, if you know one way to argue well.
