Same As It Ever Was.

By far the greatest influence is exercised by the glance. For it is by this that we express supplication, threats, flattery, sorrow, joy, pride or submission. It is on this that our audience hang, on this that they rivet their attention and their gaze, even before we begin to speak. It is this that inspires the hearer with affection or dislike, this that conveys a world of meaning and is often more eloquent than all our words.

~ Marcus Fabius Quintilianus 35-100 A.D.

Roman educator and father of modern philosophy on persuasion & rhetoric.
