The Never Ending Pool

I can't agree. Our most verifiable experience of time is our own personal history, existing as it does in an enduring "memory." We cannot really know that anything "happened" before our time. We allow this as a reality ONLY bacause we have a perception of our own past, present and future, and we can project this beyond our own experience in history and confidently assume that reality persited before us and will persist after us. But, we cannot know this, nor will we ever have the same confidence in it as a reality as we will our own personal history (memories).
