It is this example that most closely correlates with the analogy of the neural network in humans. Initially Wiener provides the example of “a feedback that is too brusque” in relation to a rudder, which will cause it to overshoot. Following this example, Wiener describes the action of picking up a pencil. Here, he says, “there must be a report to the nervous system , conscious or unconscious, of the amount by which we have failed to pick up the pencil at each instant” (7).
