Full Idea
Philosophical arguments are never incontrovertible - well, hardly ever. Their purpose is to help expound a position, not to coerce agreement.
Clarification
'Incontrovertible' means 'impossible to challenge'.
Gist of Idea
Arguments are nearly always open to challenge, but they help to explain a position rather than force people to believe

A Reaction
A bit over-cautious, perhaps. Most philosophers are converted to a position when they hear a single key argument, though it is probably 'tipping the balance' of previous discussions.
