Purpose
There has been considerable debate for over a century whether the purpose of Listing's law is primarily motor or perceptual. Some modern neuroscientists -who have tended to emphasize optimization of multiple variables- consider Listing's law to be the best compromise between motor factors (e.g., taking the shortest possible rotation path) and visual factors (see below for details).

Famous quotes containing the word purpose:
“In those days, when my hands were much employed, I read but little, but the least scraps of paper which lay on the ground, my holder, or tablecloth, afforded me as much entertainment, in fact answered the same purpose as the Iliad.”
—Henry David Thoreau (1817–1862)
“I don’t like to be idle; in fact, I often feel somewhat guilty unless there is some purpose to what I am doing. But spending a few hours—or a few days—in the woods, swamps or alongside a stream has never seemed to me a waste of time.... I derive special benefit from a period of solitude.”
—Jimmy Carter (James Earl Carter, Jr.)
“I beg to assure you that I have never written you, or spoken to you, in greater kindness or feeling than now, nor with a fuller purpose to sustain you, so far as in my most anxious judgement, I consistently can. But you must act.”
—Abraham Lincoln (1809–1865)
