A school of philosophy that celebrates putting primal needs and desires before anything else. A primalist individual will eat when they are hungry, sleep when they are tired, and do what they please when they please to.

However, a primalist may also find satisfaction in what may be more traditionally considered "primal": living outdoors, raw foods or vegan, primalsexuality, etc. Primalism, at its core, is about bringing humanity back to paleolithic or even pre-paleolithic cultural standards and lifestyle.
