THE LOGICAL FUNCTION PERFORMED BY THE PHOTOGRAPHS IN THE THOUGHTS ABOUT THE OBJECTS PHOTOGRAPHED

Abstract

The main objective of this paper is to understand the logic role played by photographs in thoughts about entities known only through photographs. I will contrast two general interpretative lines: photography as knowledge by acquaintance and as knowledge by description. The analyses of those interpretations will take into account possible relations with discussions about metaphysics of time and episodic memory. Throughout the paper I will criticize the treatment of photography as acquaintance, based on John Zeimbekis' interpretation. In its treatment as acquaintance, photography would play the logical role of a demonstrative that points to a particular entity in the past, through the causal route that links the photograph to its referent. The criticism of this concept has as its starting point the distinction between the causal referent of the photograph and its representational content (the visual properties exemplified by the photograph). The thesis here developed (along the lines proposed by Zeimbekis) is that the photographic content would not be sufficient to determine the numerical identity of the referent. Thus, it will be proposed a shift of the logic role played by photography from a referential role to a predicative. Photograph would exemplify phenomenal properties attributed to an entity known only by description.
