    The central thesis to presentism is that only the present exists; what is past no longer exists and future does not exist yet. One problem with this position is how to explicate the asymmetry of time. In ordinary talk, we say that the past is fixed whereas the future is still open. How can we cash out such metaphors? The answer, however, will not automatically follow from presentism itself because past and future are said to be ontologically on par, both being nonexistent. In this essay, I first introduce a theory of presentism, which I call Tensed-Property Presentism, and show how it can explicate the asymmetry of time.
