Abstract

The common assumption in the debate between the A- and B-theories is that there is a difference between A- and B-time. A-time has been said to be characterized by a flow, whereas B-time has been said not to consist of a flow. This way of construing the debate, however, is mistaken. Both A- and B-time possess "flow" or transition. But if this is so, we need to ask how B-time flow differs from A-time flow. I argue that none of the ways in which the difference has been characterized is satisfactory. My conclusion is that the debate between A- and B-time either needs to be recast or given up.
