Films are like Persian rugs: you keep them at their best by using them. Before you can show an old film, it has to exist -- that is, it has to have been conserved (in the archival sense). And in order to conserve it, first it has to have been "collected" (in the going-out-of-one's-way-to-rescue-and-save-what-others-discard sense). The cinema is a means towards the acquisition of knowledge in the manner of Saint Thomas: by touch. Read all you like about love, but if you haven't made love, your idea of it will be totally false.
