 Developing an analogy from Wright (1998), if it’s your turn with the kaleidoscope, you have a type of privileged perspective on the shapes and colors it presents. If someone else in the room wants to know what color dominates, for example, the most straightforward course would be to ask you. But this type of privileged access comes with no guarantee. At least in principle, you might be quite wrong about the tumbling shapes. You might be dazzled by afterimages, or momentarily confused, or hallucinating, or (unbeknownst to you) colorblind. (Yes, people often don’t know they are colorblind, a point stressed by Kornblith 1998.) It is also at least in principle possible that others may know better than you, perhaps even systematically so, what is transpiring in the kaleidoscope. You might think the figure shows octagonal symmetry, but the rest of us, familiar with the kaleidoscope’s design, might know that the symmetry is hexagonal. A brilliant engineer may invent a kaleidoscope state detector that can dependably reveal from outside the shape, color, and position of the tumbling chunks.
