"And the fourth?"
Calling time the Fourth Dimension connects it to space – and makes our brains hurt.

"Just how old are you?" Calvin asked her.
Mrs. Whatsit reminds us that our understanding of time depends on arbitrary measures, and is very local: what significance would a time system based on the Earth's revolving around the sun have for anyone outside this solar system?

[Mr. Murry] "Time is different on Camazotz, anyhow. Our time, inadequate though it is, at least is straightforward. It may not be even fully one-dimensional, because it can't move back and forth on its line, only ahead; but at least it's consistent in its direction. Time on Camazotz seems to be inverted, turned in on itself. So I have no idea whether I was imprisoned is that column for centuries or only for minutes." (10.23)
Mr. Murry suggests that time is an experience, but a shared one – he may not be able to trust his own experience, but he still feels like there's a clock somewhere he should be able to check his experience against. But if Camazotz is an entirely different planet, do "centuries" and "minutes" have any meaning?
