Beyond Order: 12 More Rules for Life

by Jordan B. Peterson

Among more differentiated and complex creatures—the larger and commonly recognizable denizens of the natural world—the sensory and motor functions separate and specialize, such that cells undertaking the former functions detect patterns in the world and cells in the latter produce patterns of motor output. This differentiation enables a broader range of patterns to be recognized and mapped, as well as a broader range of action and reaction to be undertaken. A third type of cell—neural—emerges sometimes, as well, serving as a computational intermediary between the first two. Among species that have established a neural level of operation, the “same” pattern of input can produce a different pattern of output (depending, for example, on changes in the animal’s environment or internal psychophysical condition).
