Abstract

The Growing Block Theory of time asserts that temporal reality encompasses all present and past things. The world grows as things come to be present. When something becomes past it does not cease to be, it simply moves away from the growing edge of reality. Thus past things are just like present ones, except not present. But if past things are just as real as present ones, and qualitatively just like them, how can I tell if what is happening is present and not past? It seems everything would look the same to me whether I was past or present. And so I don’t know that I am present. To avoid this intolerable result, I argue on behalf of the Growing Block Theorist that the present does not look the same as the past. Experiences exemplify the property of presentness when they are present, and I can be directly acquainted with that fact. My direct acquaintance enables me to be justified in believing my experiences are present and to know the same. I develop this view and conclude by responding to objections.
