Being and Existence

The concept of "Being and Existence" as Lacan deploys it here names a structural division — not a philosophical given — that is produced by a specific formal operation: Pascal's Wager. Lacan reads the Wager not as a piece of probability calculus or a prudential argument for belief, but as the staging of a radical split within the subject. On one side stands being — what the subject is prior to and beneath any particular form of life, including its mortal existence; on the other side stands existence — the contingent, finite life that is staked and potentially lost in the Wager. The crucial move is Lacan's identification of the "nothing" that is risked (the life one may lose) with objet petit a: not sheer nullity but the irreducible remainder or cause of desire, that ungraspable object-void which is not nothing but rather "no being" in the technical Lacanian sense. The Wager thus becomes a structural analogue of the subject's constitutive loss — the cession of a piece of being that produces the desiring subject.

What the Wager reveals, on this reading, is that existence is not the ground of being but rather something staked against it, separable from it, and ultimately identifiable with that fragment of real enjoyment (objet a) whose loss is the condition of desire's possibility. The "division between being and existence" is therefore not a metaphysical taxonomy but a topological split internal to the subject's relation to the Real — a real understood as the impossible-to-question, the brute fact of chance (hasard) that no symbolic calculation (probability theory) can domesticate. The wager formalises what psychoanalytic experience discovers structurally: the subject is always already split between what it is (a void, a site of being) and the contingent existence it inhabits and must risk.

This concept appears in jacques-lacan-seminar-13 and jacques-lacan-seminar-13-1 (both at p. 122), making it a single theoretical moment within Lacan's thirteenth seminar. Within the seminar's broader argument, the Being/Existence split functions as a hinge between the theory of the subject and the theory of the Real. It is an extension — or rather a specification — of the canonical concept of objet petit a: whereas objet a is generally characterised as the structural remainder produced when the subject enters the Symbolic, the Being/Existence split names the precise experiential or formal occasion (the Wager) at which that remainder becomes visible as the gap between what is staked (existence) and what cannot be staked (being). The concept thus sharpens the canonical account of Desire by locating its cause (objet a) at the divide between these two registers rather than at some inner psychological origin.

The cross-reference to the Real is equally central: by identifying chance (hasard) with the Real qua impossible-to-question, Lacan positions the Being/Existence split as the point at which the Real irrupts into existential experience. This aligns with the canonical principle that the Real is not the raw world but precisely what resists symbolisation — and Pascal's Wager, stripped of its probabilistic veneer, becomes the formal structure that forces the subject to confront that resistance. The concept is also in implicit dialogue with the canonical treatment of the Infinite: the Wager's structure (a finite stake against an infinite prize) is precisely the "bad infinite" logic that Lacan subverts by locating the real stakes not in the calculation of gains but in the subject's relation to that which cannot be calculated — the Real. The Act (another cross-referenced canonical) is implicitly at stake as well: the Wager requires an act that cannot be grounded in knowledge, mirroring the Lacanian Act as a leap beyond the subject's symbolic resources.

the important thing is not at all this suspense in so far as it is radical, but the division that it introduces between being and existence.

The quote is theoretically loaded because it performs an explicit redirection: by dismissing the "suspense" (the dramatic uncertainty of the Wager's outcome, which is the focus of probabilistic readings) as not "the important thing," Lacan displaces the entire register of calculation and stakes his interpretation on the structural division — a term that resonates directly with the barred subject ($) and the split between being and existence that the Wager enacts rather than merely represents.
