Medusa

Medusa is Sartre’s image for the way the Other’s look petrifies the for-itself: what had been the nothing by which things appear becomes, from outside, a thing among things. The myth gives a vivid figure to the tension between consciousness’s transcendence and the object-being conferred on it by another.

The Look and Petrifaction

Alone, the for-itself transcends the world; it is the nothing through which things are disclosed. The Other’s appearance changes this relation. The Other’s look fixes the for-itself in the in-itself, placing it within the world as an object among objects. Sartre identifies this petrifaction as the profound meaning of the myth of Medusa.

An Outside That Cannot Become the Whole

This objectification does not erase the for-itself’s distinctive mode of being. In its encounter with the Other, it is indeed present in the midst of the in-itself, but this is its outside: by nature, the for-itself cannot coincide with its being-in-itself. Medusa therefore figures a real transformation in how the self exists for others, not a final conversion of consciousness into a thing without remainder.

Place in the Argument

The image follows Sartre’s account of the for-itself as the nihilation and radical negation of the in-itself. The encounter with the Other adds a second aspect to that account: the for-itself is also fixed as in-itself in the world. Medusa condenses this reversal into a single mythic image, making visible how another’s presence can confer an object-being that solitary consciousness does not possess in the same way.
