Imagine that Alice lives in a classic growing block world, while Twin Alice lives in an eternalist world. Otherwise, the two worlds are exac...

Compare two worlds: Evanescent World (EW): There is a rich three-dimensional reality that exists for only one moment of time. Timeless Wo...

I’ve been thinking a lot this semester, in connection with my Philosophy of Time seminar, about whether the A-theory of time—the view that t...

For years I was convinced that the extrinsic constitution model of divine knowledge, which theists who accept divine simplicity must accept,...

Famously, Boethius says that an eternal being, unlike a merely temporally everlasting being, embraces all of its infinite life at once, “pos...

Argument One: If from x ’s point of view there is an objective fact about what time it presently is, then x is in time. If x knows an o...

One can only know a proposition when it is true. One can only know a proposition when one exists. Thus, one can only know a proposition i...

I ran across this old post of mine and it made me think that there is an interesting distinction between two kinds of change which one migh...

It’s common to say that presentism entails the A-theory. But that’s not so clear. Suppose that time can pass in the absence of change. Now i...

When I think about McTaggart’s famous argument against the A-theory of time—the theory that it is an objective fact about the universe what ...

Classical theism holds that God is timeless and knows all objective truths. According to A-theories of time, objective truths change (e.g., ...

Imagine it’s the last moment of time. What’s next for you? Nothing! It’s a terrifying time, but it’s one that’s hard to describe well. Phras...

Suppose that the full saturated truthbearers are tensed propositions (which I think is essentially what the A-theory of time comes to). Now ...

For this post, suppose that an A-theory of time is true, so there is an absolute present. If we think of possible worlds as fully encoding h...

Suppose: There are tensed facts. If F is a contingent fact solely about physical reality that does not depend on creaturely free choice,...

Let’s suppose that the universe has a beginning and the tensed theory of propositions (which is accepted by most A-theorists) is true. Then ...

In a computer, we have multiple layers of abstraction. There is an underlying analog hardware level (which itself may be an approximation to...

Here is a standard story about Special Relativity and the A-theory of time: There is an objective metaphysical simultaneity, but this met...

There is a structural similarity between the main reasons for adopting the A-theory of time and the knowledge argument against physicalism. ...

This argument is valid: An object that really changes from being F to being G first exists at a time at which it is F and then exists a...
