Does time differ from change? Philosophical appraisal of the problem of time in quantum gravity and in physics: A response

In this paper I respond to the paper "Does time differ from change? Philosophical appraisal of the problem of time in quantum gravity and in physics" by Alexis de Saint-Ours, in which, among other things, he contrasts the views of Rovelli and myself. There are three main parts in my response. First, I consider Saint-Ours's question about the relationship between time and change and whether it is possible to have the latter without the former. Second, I go into somewhat more detail about the differences between Rovelli and myself concerning the nature of relationalism. Finally, I take the opportunity to discuss how my ideas about the nature of time have changed during the last decade as a result of examination of the role played by scale in the dynamics of the universe.
