“The possible is an option on being”
Being and Nothingness“The possible is an option on being” names a central claim about possibility: it is not a property that an idea acquires through affirmation, negation, or expectation, but an opening onto being made possible by human reality’s relation to itself. Possibility exists because the For-itself is not simply what it is; it stands apart from itself in the form of what it may be.
Possibility as a relation to being
The expression compresses an argument against treating possibility as a quality contained in a representation. Neither affirming that a centaur exists nor denying its existence can make the centaur possible. Nor can a synthesis of affirmation and negation explain possibility merely by adding those two acts together: the synthesis would itself need to be understood as an organized whole with its own meaning. Similarly, not knowing whether an idea corresponds to reality leaves the mind indifferent; ignorance cannot grant the idea a claim upon the real.
Expectation does not supply the missing ground. Tendencies that incline someone to anticipate one outcome rather than another already presuppose a relation to possibilities; they do not create that relation. Apprehending something as possible therefore requires an original surpassing, rather than a subjectivity closed within what it already is.
The For-itself as its own possibility
The possible can enter the world only through a being that is its own possibility. For human reality, this means existing not merely as what it presently is, but as the right to be what it is. The language of a right exposes a separation: property becomes a right when it can be contested, whereas the undisturbed enjoyment of what one possesses is simply a fact. In the same way, possibility entails a distance between human reality and the being it has the right to be.
This distance is not an accidental gap added to an otherwise self-contained subject. The possible is an aspect of the For-itself that escapes it precisely insofar as it is the For-itself. It belongs to the structure through which human reality exceeds its present state, and is described as a new aspect of the nihilation of the In-itself in the For-itself.
Why objects do not possess possibilities by themselves
The In-itself, which is what it is, cannot have possibilities in its own right. A possibility relating objects to a possible outcome arises only through a being that stands before possibilities and organizes the objects in relation to them. The example is a billiard ball rolling over cloth: the possibility that the ball will be stopped by a fold belongs neither to the ball nor to the cloth considered separately. It emerges when a being comprehends the ball and cloth as a system in which that outcome can occur.
Such comprehension cannot simply come from outside, from the In-itself, and it cannot be reduced to a private thought detached from the being that thinks. It must coincide with the objective structure of the being that comprehends its possibles. The expression thus marks a double refusal: possibility is neither a ready-made feature of things nor an arbitrary projection of a sealed-off subject. It arises through human reality’s being open to what it is not yet.
