This Aristotelian treatise makes up part of the philosopher's Parva Naturalia, which is Latin for "short treatises on nature." In this text, he presents his ideas about the human senses. He connects each sense to an element—sight to water, touch to earth, etc. While Aristotle's view of the senses is scientifically inaccurate in many ways, this treatise is a fascinating read for anyone interested in learning more about how the ancients understood the world.
