 Price (2011) has replied to Maudlin by abandoning the claim that the units in “one second per second” cancel, leaving a pure number. He now insists, rather, that a ratio of a quantity to itself can not be a rate at all. Maudlin’s example only seems to evade this point by supposing a ratio of dollars offered to dollars returned. That ratio differs, as he sees it, in an essential way from the ratio of one second to one second or, for that matter, from the ratio of one mile to one mile, which are both ratios of quantities to themselves. Neither in his view can be a rate, and the former ratio is no more characteristic of time than the latter ratio is of space.
