In doing that, we show that there may exist also entities without identity, and emphasize the importance of paying attention to the metalanguage of scientific theories, for they may be also fundamental in determining the theory's ontological commitment. date: 2007-04 date_type: published citation: Krause, Decio (2007) Entity, but no Identity.
