Abstract
'Photo-credit: David Hume': a dialogue showing how application of Hume's three vivacity principles of resemblance, contiguity and causation--even his illustrations of them--not only immediately clarify the main sources of interest in photography, but locate photography in the broad and fascinating history of various functions that images serve us, thereby dispelling ongoing mystification about it. (In the dialogue, Veronica represents our contiguity and causal interests, Miranda [named for a Japanese camera company] our depictive ('resemblance') interests, while Clara serves as philosophical moderator.)
