 According to presentism, all that is physically real is the present—a system of physical events all of which are simultaneous with each other. No other events are real. Precisely what this system of events may be, now, as I snap my fingers, may not be known to me; but there is a fact of the matter as to what it is, and it is a universal fact which embraces us all. It is an intersubjective reality—now, as a snap my fingers—and it is a reality which contains us only as an incidental part. But even if one knew all that there is to know, consistent with special relativity, one would not be able to say what this system of events might be. According to presentism, therefore, special relativity is radically deficient as a description of reality. It is blind to the sequencing of what is physically real. (2002: 279–80)
