The Passage of Time

What, if anything, are we talking about when we say that time passes? In the Western tradition, philosophical investigations on the nature of time divide between realist approaches according to which there is a truth beyond the metaphor of the passage, and anti-realist approaches according to which the passage of time is ultimately an illusion. In this contribution, I will overview the logical space in which various options for the realist and the antirealist are to be found: time idealism and passage antirealism, various forms of standard realism, and non-standard forms of realism of passage.
