 Next, we turn to an objection to presentism that concerns the idea that time really passes. The challenge, put simply: presentism isn’t compatible with time’s passage. This is a problem since presentism is a view that requires that reality is “dynamic” and that there is a change in what exists over time, which is usually described in terms of the passage of time. (For the purpose of this entry, we ignore general arguments to the conclusion that time doesn’t really pass and, instead, focus on specific challenges to presentism.)
