When a prehistoric artist pressed a pigment-covered hand to a cave wall and blew color around it, something remarkable happened. The resulting outline was a declaration of presence and also an admission of absence. The handprint was not a hand. It was a trace of someone who lived, breathed, hoped, feared, hunted, loved, and eventually vanished. This gap between representation and reality has always shaped how humans express themselves.

Magritte reminded us of the same truth much later with a pipe that "was not a pipe." His painting has become a classic example of a meta-message, a communication about communication itself. Like Alfred Korzybski's insight that "the word is not the thing" and "the map is not the territory," or Denis Diderot's literary experiment This Is Not a Story, Magritte's work highlights the fundamental gap between symbols and what they represent.
We intuitively recognize that no medium can ever contain the living substance of the person who created it. This very blog post is its own meta-message, acknowledging that these words about representation are themselves only representations, and that this post about the impossibility of digital presence is itself an attempt at digital presence.
This tension sits at the heart of every form of self expression. The medium gestures toward the self but never equals it. And yet we continue to endeavor, knowing the attempt will always fall short.
