- "This interaction between perception and action is also seen in what psychologists call perpetual constancies. For us, an object can remain recognizable as the same object while our viewpoint on it changes. (...) Perceptual constancies are see in a fairly wide range of animals, including octopuses and some spiders, as well as vertebrates." #Other Minds by Peter Godfrey-Smith #Peter Godfrey-Smith
