Although physicists stifl de- bate the details of this proposal, Boltz- mann convincingly plucked away one fea- ture of Newtonian time. There is only one “me” in the detenser’s universe with endurance, but many times; and many of them have an equal right to represent my perspective — the perspective from which I view the universe. Chapter 9 asks callenver philosophical Q: Answering the second question would go a long way towards recovering manifest time.
Researchers must now reverse this train of thought and reconstruct the time of experience from the time of nonfundar mental physics, which itself may need to be reconstructed from a network of cor- relations among pieces of a fundamental static world.
In fact, there is much more even in this chapter, but I will discuss only the point relevant to the main thread of the book.
Computing and the WorldCambridge: General relativity, too, lacks Newtonian time, but at least it has various partial substitutes that together behave like New- tonian time when gravity is weak and rel- ative velocities low.

Tearing Spacetime Asunder 4. Using it, physicists are able to calculate the probabilities of any experimental outcome at any time.
This struc- ture is built into our language, thought and behavior. In fact, he presents the reader with what he calls an informal dilemma: Edited by Craig Callender. University of Toronto Press. But canonical quantum gravity al- ready offers a more developed idea.

Although it is hardly possible to address this issue in full in a single chapter Chapter 4: The theory’s probabilistic predictions require time to have certain features. To the left of the wall, the ball appears in two positions; on the right, it does not appear at all.
According to one, time may arise from the way tkme the universe is parti- tioned; what we perceive as time re- flects the relations among its pieces.
Craig Callender assures us that many physicists believe in the latter and far more bizarre theory. Recent research attempts to perform just this feat.
It should be acknowledged that being present is no part of the content or the phenomenology of my typing experience. Remarkably, the illlusion, relative to the nucleus, obeys the standard time-dependent equation of quantum mechanics. Instead, I think I am simply having this experience, rather than the experience of eating breakfast earlier this morning.
We perceive time because we are, by our very nature, one illusino those pieces. They include the metrical distinctions associated with the signature of realistic spacetime metrics, the one-dimensionality of time, the “mobility asymmetry” we can go back and forth in space, but not in timedirectionality “time arrows”and the existence of timelike but not spacelike “genidentity lines.
No single feature of physical time deserves to be called ” the difference. What follows is a comprehensive tour of philosophy of time from Callender’s perspective, written with great insight, as well as wit and flair.
This is right on.

Suppose, for simplicity, that each common now is stitched from the local “present patches” of the same participants. As already noted, Callender thinks this question may be empty.
The present moment does not exist in them and therefore neither does the flow of time. In Chapter 7 Callender proposes a new difference between time and space. But relativity does away with it, presenting the friends of “tensed time,” “absolute becoming,” and other A-theoretic notions with the unpleasant dilemma of having to choose between structures that may be congenial to manifest time but are not relativistically invariant e.
