Is Phenomenology of Perception already the break with Sartre?

Yes — philosophically, if not socially. Part Three Ch III of Phenomenology of Perception — the chapter on freedom that closes the book — is a chapter-length rejoinder to Sartre's Being and Nothingness (1943). Sartre is never named. Every constructive move is a counter-Sartre move. The 1955 political break that will end the friendship in Adventures of the Dialectic is not a new rupture; it is the public actualization of a rupture whose philosophical substrate was already complete ten years earlier. The wiki's standard story — MP and Sartre together through the 1940s, political break in 1955 — preserves the social history at the cost of misdescribing the philosophical history.

The Short Answer

The Freedom chapter opens with the formulation MP will demolish: "Our freedom is either total or non-existent. This is the dilemma of objective thought and its accomplice, reflective analysis" (PhP p. 519). This is near-verbatim Being and Nothingness — Sartre's 1943 position that consciousness is nothingness at the heart of being and that the for-itself is its own free projection with no middle term. Everything that follows in the chapter is point-by-point refusal:

  1. Freedom by means of motivations, not in spite of them. "I am free, not in spite of or beneath these motivations, but rather by their means. For that meaningful life, that particular signification of nature and history that I am, does not restrict my access to the world; it is rather my means of communication with it" (p. 520). This is a structural rejection of the Sartrean dualism of freedom/facticity — see conditioned-freedom, motivation-mp.

  2. "Class is prior to class consciousness." The day-laborer does not decide to be a proletarian (Sartrean voluntarism), nor is he objectively placed (orthodox Marxism); he exists as a worker in a pre-predicative mode of being-in-the-world. "Idealism and objective thought equally miss the arrival of class consciousness... because they are unaware of the relation of motivation" (p. 510). Both alternatives — Sartre's and orthodox Marxism's — are condemned in the same sentence.

  3. The prisoner example (p. 518). Sartre's tortured prisoner who refuses to talk demonstrates (for Sartre) that consciousness always has total freedom. MP's same prisoner is not free "through a solitary and ungrounded decision" but through "a certain mode of Mit-Sein" — a long-prepared commitment sustained by comrades, political engagement, daily life. "It is not ultimately a bare consciousness that resists the pain, but the prisoner along with his comrades."

  4. "I am a psychological and historical structure" (p. 520). The closing synthesis. The self is not a néant but a structure. Existence comes "with a way of existing, or a style" — not self-made from nothing.

  5. The book's closing sentences. "Freedom... becomes mired in the contradictions of commitment and does not notice that it would not be freedom without the roots that it thrusts into the world" (p. 521). Freedom needs its roots; Sartrean freedom was defined by their absence.

None of these is a minor disagreement. Together they amount to a rejection of Being and Nothingness's governing ontology.

Why, then, is Sartre not named?

Three plausible reasons, which are not mutually exclusive:

  • Sartre was MP's friend and political co-founder. Les Temps Modernes was founded in 1945, the same year as PhP; Sartre and MP would edit it together for a decade. The Freedom chapter could not have ended a friendship that was about to be launched.
  • MP is more interested in the position than in its author. The "dilemma of objective thought and its accomplice, reflective analysis" is framed as a structural error, not a personal one. Sartrean freedom is an instance of this error, not its only instance.
  • The argument is meant to stand on its own. To name Sartre would invite a defensive response where MP wants a structural critique. The unnamed demolition has more philosophical force.

But whatever the reason, the absence of Sartre's name does not make the argument less Sartrean-targeted; it may even sharpen it, by forcing the reader to recognize the target on their own.

What This Reframes

If the philosophical break is already complete in 1945, several features of the MP/Sartre trajectory look different.

The 1955 Adventures of the Dialectic is not a new position

The conventional reading: MP in 1955 is disillusioned by Sartre's Communism-without-the-party, and Adventures of the Dialectic is the public articulation of a newly-felt philosophical distance. The revised reading: MP in 1955 is saying publicly what PhP 1945 already argued. Adventures's critique of Sartrean "ultrabolshevism" is an application of PhP's critique of Sartrean voluntarism. The philosophical content has not changed; only the willingness to name the opponent has.

This is confirmed by the 1954–55 Passivity course's critique of Sartre, which is continuous with PhP's critique: the Passivity course's "lateral passivity" thesis is the 1954–55 version of PhP's argument that freedom operates by means of motivations, not in spite of them. See passivity.

The Signs Introduction's long Sartre-meditation is a culmination, not a reversal

The 1960 Introduction to Signs contains MP's longest public engagement with Sartre — a 13-page meditation on the Sartre of the Aden Arabie preface and the Saint Genet essay. The meditation is sometimes read as MP's final revision of his relationship with Sartre. On the "PhP-already-breaks" reading, it is something more interesting: MP's final public statement of a position he has held for fifteen years. What makes it possible is that after 1955 the break is no longer socially costly; by 1960 MP can say, for the first time, what he has always thought.

The 1959 retraction of the tacit cogito does not change anything

The January 1959 working note retracting "the tacit cogito" is the clearest example of MP explicitly disavowing a position in PhP. But crucially, it is not the Freedom chapter MP retracts. The tacit cogito is retracted because it remains "a variant of the pensée de penser" — i.e., because it remains too Cartesian, not because it remains too Sartrean. On the Sartre question, the 1945 position is unchanged all the way to MP's death in 1961. This is itself significant: if MP had changed his mind about Sartre philosophically, the 1959–61 working notes would show it, and they do not.

Caveats and Tensions

  • Sartre in the 1940s was not yet the Sartre of the Critique of Dialectical Reason. The Critique (1960) develops a position considerably closer to MP's, with serialized action, practico-inert structures, and the historical sedimentation of projects. It is possible that by 1960 the philosophical distance had narrowed even as the political distance had widened. MP himself does not say this explicitly, but the Signs Introduction acknowledges that Sartre 1960 is not Sartre 1943.
  • The 1945 critique is of a specific Sartre text, Being and Nothingness. MP is not criticizing "Sartre as such"; he is criticizing a particular ontology. Sartre's 1948 essay "Black Orpheus" and the 1946 Anti-Semite and Jew have different targets and different vocabularies — and MP does not engage them in PhP.
  • Beauvoir's Ethics of Ambiguity (1947) develops a position very close to MP's Freedom chapter, though still in Sartrean vocabulary. If Beauvoir was working toward conditioned freedom from within Sartrean ontology as early as 1947, the philosophical break was not uniquely MP's — which complicates the "MP vs. Sartre" framing by adding a third term.
  • The chapter's argumentative success is not unanimous. Sartre in the Critique would say that the prisoner example is still a choice, just a choice made within a sedimented situation, and that MP's "by means of motivations" is a matter of emphasis rather than principle. The philosophical distance may be real but smaller than MP's rhetoric suggests.

What Follows

If this question's answer is right, three things follow for how the wiki should treat the MP/Sartre relationship:

  1. The 1945 rupture should be a primary fact, not a revisionist claim. The conventional story of "political break in 1955" should be corrected in the direction of "political actualization of a 1945 philosophical break."

  2. conditioned-freedom is load-bearing for the MP trajectory in a way that is easy to miss if the Freedom chapter is read as a technical addendum to PhP rather than as the book's closing statement. The whole book has to end in the Freedom chapter; everything the body-schema, the phenomenal field, operative intentionality, and motor intentionality do in the book converges on the demolition of Sartrean freedom in the final chapter.

  3. The wiki's jean-paul-sartre page should record Sartre's role as the primary unnamed interlocutor of PhP Part Three, not merely as the post-1955 political antagonist. This is already done in the page's "PhP Part Three Ch III: The Unnamed Break (1945)" section, added during the PhP ingest.
