VOL. 01 / CAUSAL CLAIMS / OPEN DEBATE
▲ PREMISE §1.01

You think X causes Y?

Let’s trace that thread. Every causal claim is a knot of smaller claims pretending to be simple. We’re here to pull at the knot — gently, repeatedly — and see what unravels.

◇ REBUTTAL §1.02

Correlation is a well-dressed stranger. It shows up to every cause-and-effect party uninvited.

■ EVIDENCE §1.03

In 1854, Dr. Snow mapped cholera onto a London street. The pump on Broad Street was not suspicious until the map made it so.

— a data-shaped story
? ASKING §1.04

What if the effect is quietly authoring its cause?

● PULL QUOTE §1.05
“A cause is a story we believe hard enough to reverse time with.”
— margin note, 3am
◐ CONTEXT §1.06

Hume woke up one morning and decided that necessary connection was just a habit of mind. Breakfast was probably involved.

△ CLAIM §1.07

Every argument fits in a box. Every box leaks.

i.

A butterfly

flaps its wings, allegedly, in a place you’ve never been.

ii.

A pressure shifts

by a fraction that instruments pretend not to measure.

iii.

A ship reroutes

though the captain insists the sea is personal.

iv.

You miss a train

and swear the butterfly is, somehow, your fault.

This is a chain only because we drew it as one. The arrows point forward because paper likes it that way.

PREMISE

Causes are singular.

A is responsible for B. The rest is noise. Call a lawyer and a statistician.

I
REBUTTAL

Causes are a crowd.

B arrived at its own party with twelve friends. A was just the loudest.

II
EVIDENCE

The kitchen fire.

Was it the match, the oxygen, the paper, the dry year, or the forgetful hand? Yes.

III
CONCLUSION

Pick the cause you can move.

Causality is partly ethics. We blame what we can change.

IV
PREMISE

Time is the tell.

Causes arrive before effects. This is the only rule we don’t argue about, yet.

V
REBUTTAL

Memory runs backward.

We remember causes after effects, which is how we invent half of them.

VI
EVIDENCE

Granger’s test.

If X helps predict Y’s future, we call X a cause. The economists are smiling politely.

VII
CONCLUSION

Prediction ≠ cause.

The rooster predicts the dawn. He is not its author, though he believes otherwise.

VIII
PREMISE

Counterfactuals.

X caused Y iff, without X, Y would not have occurred. A sentence that costs physics nothing and philosophy everything.

IX
REBUTTAL

Which world?

The world without X is also a world without the neighbor, the weather, the particular Tuesday. Pick one.

X
EVIDENCE

The randomized trial.

Flip a coin to decide who gets the cause. Wait. Count. Argue about the coin.

XI
CONCLUSION

Provisional, always.

Every cause is on probation. That’s not a flaw in the court; it’s the court.

XII
◎ DRIFT

The cells here stop behaving. That is the point.

◎ SLIP

Some arguments were only holding hands with the grid.

◎ DRIFT

Confounders enter the room. The lights flicker.

◎ SLIP

The data was collected on Tuesdays. Tuesdays are not random.

◎ DRIFT

A third variable is watching everyone from the doorway.

◎ SLIP

The instrument was measuring its own enthusiasm.

◎ DRIFT

We are not certain. We are not ever certain.

◎ SLIP

The argument is now shaped like the argument.

◆ CONCLUSION §5.01

The grid reassembles.

Not back to where it was — somewhere honest. The thesis survives, but humbler. The rebuttals sit closer. The evidence no longer pretends it arrived alone. This is what a finished argument looks like when you are willing to be finished with it.

▲ RESTED §5.02

X causes Y, sometimes, under pressure, in the presence of a witness, if the door is open.

◇ RESTED §5.03

The rebuttal does not disappear. It has a chair now.

■ LEDGER §5.04
  • causes observed: many
  • causes proven: fewer
  • causes believed: unchanged
  • arguments won: not the point
● PULL QUOTE §5.05
“The point of the argument was the argument. The point of the cause is to live as if one exists.”
◆ SIGN-OFF §5.06

The door stays open. Bring your own doubts.
