When does a conclusion follow, and when is it a prediction?

A rule can tell you what must follow if its premises are true. A pattern in observations can suggest what you may find next. Deduction and induction make these different kinds of move: a valid deduction still needs true premises, while further observations can overturn an inductive generalization.

Is the red you see the same red that I see?

We can agree that a tomato is red and choose the same matching paint. Does that agreement show that red feels the same to each of us? The puzzle separates what we can compare publicly from what another person’s experience is like.
