Pathophysiology is the key to disease. To a physician, the word has connotations that convey both the philosophy and the aesthetic of poetry—not surprisingly, part of its Greek root, physiologia, has a philosophic and poetic meaning: “an inquiry into the nature of things.” When pathos—“suffering” or “disease”—is prefixed to it, we have a literal expression of the essence of the doctor’s quest, which is to make inquiry into the nature of suffering and disease.
