Thesis Some films do philosophy that prose cannot, rather than illustrating it
Where it stands
I'll argue a thesis my analytic friends here find indulgent: some films do philosophical work in their own right, work that can't be fully restated in prose.
The sceptic's argument is simple. Whatever philosophical content a film has can be put into words: indeed, critics explaining it always do. So the film is a vehicle for ideas found elsewhere. And films can't do what philosophy does: state premises, draw inferences, be refuted.
My reply has two parts.
First, a film can put the viewer in a position rather than describe one. It can withhold information so the audience shares a character's ignorance, then reveal it so they feel the correction. Questions about self-deception, about memory, about whether you'd recognise the person you love, become available as experience. A paper can describe that experience. It can't make it happen to you.
Second, Stanley Cavell. In Pursuits of Happiness he reads the Hollywood ‘comedies of remarriage’ (The Philadelphia Story, His Girl Friday, Adam's Rib and others) as working through what marriage is: a couple must be re-acknowledged, chosen again, through conversation. I think those films are a contribution to the philosophy of love and of recognition that couldn't have been written as a treatise, because what they show is the tone in which acknowledgement happens.
Noël Carroll and others are sceptical of this kind of claim, and I respect their caution. But I think the restatement objection proves too much: you can paraphrase a poem, too.
