Zeno's Paradox Explains Why You Can't Get Out of Bed
Zeno argued you can never cross a room, because half the distance always comes first. The same regress keeps you in bed, and one sum dissolves it.
Zeno of Elea, a Greek philosopher of the fifth century BCE, argued that you can never cross a room. Before you reach the far wall you must reach the halfway point. Before that, the quarter point. Before that, the eighth. The list of required first steps has no first entry, so motion never begins.
Nobody believes this, and everybody lives it at 6:40 a.m.
Lying in bed, the regress runs fast. First I need to wake up properly. Before that, check the time. Before that, decide whether today counts. Each “first I need to” has another one behind it, and the pile has no bottom.
Why the paradox dissolves
Add up the distances: 1/2 + 1/4 + 1/8 and so on. The total is 1. Infinitely many pieces, one finite room. The pieces shrink in time as well, so the walk takes a normal number of seconds. The infinity was bookkeeping, not a wall.
The bed version works the same way. The preparations you keep inventing are not a real queue. Most are imaginary.
The smallest physically possible step
Skip the sequence and pick the smallest action your body can perform: put both feet on the floor, which is also a workable label for the 6 a.m. alarm itself. It needs no plan, and the next movement is then already available. Marcus Aurelius opened his pep talk about getting out of bed by reminding himself what he was getting up for.
DontSnooze, an iPhone app, attacks the regress from the other side: after the alarm you have 30 seconds to film proof you’re up, so the infinite series gets a deadline.
Camus’s Sisyphus is the same walk, repeated daily. Zeno never refuted the walker. The walker simply never waited for the argument to finish.
