The Cogito — Descartes's foundational proposition 'I think, therefore I am' — occupies a position of peculiar centrality in the depth-psychological corpus, serving simultaneously as the cornerstone against which phenomenological, hermeneutical, and post-structuralist critiques are levelled and as a persistent reference point for understanding the constitution of selfhood and subjectivity. Ricoeur treats the Cogito as paradigmatic of philosophies of the subject, situating his hermeneutics of the self at an equal distance from the 'apology of the cogito and from its overthrow,' while tracing its displacement first by the God-idea within Descartes's own system and then by Nietzsche's hyperbolic scepticism. Merleau-Ponty, in a sustained examination occupying a dedicated chapter of the Phenomenology of Perception, contests the disembodied, atemporal self-transparency the Cogito implies, restoring to it what he calls 'temporal thickness' and insisting that self-consciousness is not a pure reflexive act but is embedded in bodily comportment and expression. Hillman reads Deconstructive moves in French thought as 'modes of decapitating the cogito,' yet argues they remain caught within it. Descartes's own text anchors the discussion with the Second Meditation's claim that the thinking thing is 'the only thing that cannot be stripped from me.' The major tension running through these encounters is whether the Cogito can survive its own scrutiny once language, body, time, the unconscious, and divine alterity are restored to the analysis.
the quarrel over the cogito, in which the 'I' is by turns in a position of strength and of weakness, seems to me the best way to bring out the problematic of the self
Ricoeur frames the entire hermeneutics of selfhood around the contested status of the Cogito, proposing that his own project steers between uncritical affirmation and nihilistic dissolution of the 'I think.'

By a sort of rebound effect of the new certainty (namely that of the existence of God) on that of the cogito, the idea of myself appears profoundly transformed... The cogito slips to the second ontological rank.
Ricoeur argues that within Descartes's own system the Cogito is ontologically demoted once the idea of God is established, revealing the instability of the first-person foundation from the outset.

'I doubt': there is no way of silencing all doubt concerning this proposition other than by actually doubting, involving oneself in the experience of doubting, and thus bringing this doubt into existence as the certainty of doubting.
Merleau-Ponty reinterprets the Cogito as a performative, embodied act rather than a purely intellectual intuition, arguing that certainty arises through lived enactment rather than reflective self-presence.
, Phenomenology of Perception, 1962thesis
we are restoring to the cogito a temporal thickness. If there is not endless doubt, and if 'I think', it is because I plunge on into provisional thoughts and, by deeds, overcome time's discontinuity.
Merleau-Ponty argues that the Cogito must be temporalised and rendered existentially thick rather than treated as a self-identical, instantaneous act of pure reason.
, Phenomenology of Perception, 1962thesis
this cogito should be: 'One thinks, therefore one is.' The wonderful thing about language is that it promotes its own oblivion... Descartes nowhere mentions it.
Merleau-Ponty contends that the Cogito is secretly mediated by language and expression, a dimension Descartes suppresses, making the apparent immediacy of self-consciousness a linguistic artefact.
, Phenomenology of Perception, 1962thesis
doubting is thinking; next, the 'I am' is connected to the doubt by a 'therefore,' reinforced by all the reasons for doubting, so that we should read: 'To doubt, one must be.'
Ricoeur clarifies the logical structure of the Cogito, showing that the existential claim is inseparable from the act of doubting, establishing self-existence as a propositional necessity rather than a mere feeling.
, Oneself as Another, 1992thesis
the cogito has to succumb to this version (which is itself hyperbolic) of the evil genius, for what the latter could not encompass was the instinct for truth. Now this is precisely what has become 'enigmatic.'
Ricoeur argues that Nietzsche's radicalised scepticism defeats the Cogito by targeting the will-to-truth itself, the very resource Descartes relied on to escape universal deception.

The shattered cogito: this could be the emblematic title of a tradition, one less continuous perhaps than that of the cogito, but one whose virulence culminates with Nietzsche, making him the privileged adversary of Descartes.
Ricoeur names a counter-tradition of 'cogito-shattering' that runs from Descartes's critics through Nietzsche, setting the dialectical frame within which depth-psychological accounts of selfhood must operate.

deconstructive moves may be French modes of decapitating the cogito... it stops short and remains an exercise of the cogito. The guillotine blade never quite cuts through.
Hillman argues that poststructuralist deconstruction, despite its apparent radicalism, remains trapped within the very cogito it seeks to dissolve, failing to achieve the truly alchemical transformation of mind.

it is thought; this alone cannot be stripped from me. I am, I exist, this is certain. But for how long? Certainly only for as long as I am thinking
Descartes's primary text establishes the Cogito's temporal and conditional character: existence is guaranteed solely by the ongoing act of thinking, a restriction that subsequent critics exploit.
, Meditations on First Philosophy, 2008thesis
the Cogito can be interpreted as a combination of primary intuition ('I think') and immediate inference therefrom ('I exist')... a quite different interpretation holds that the Cogito is to be understood in terms of performance
This editorial passage surveys the interpretive field, contrasting the inferential and performative readings of the Cogito, both of which bear directly on depth-psychological accounts of self-awareness.

All thought of something is at the same time self-consciousness, failing which it could have no object... Self-consciousness is the very being of mind in action.
Merleau-Ponty rearticulates the Cogito's structure in phenomenological terms, insisting that intentionality and self-awareness are co-original rather than sequentially related.

this book, once begun, is not a certain set of ideas; it constitutes for me an open situation... my consciousness takes flight from itself and, in them, is unaware of itself.
Merleau-Ponty illustrates how lived consciousness typically escapes reflexive self-presence, undermining the Cogito's assumption that self-awareness is the mind's natural resting state.

there are so many things besides in the mind itself that can serve to make the knowledge of it more distinct, that there seems scarcely any point in listing all the perceptions that flow into it from the body.
Descartes's text extends the Cogito's self-knowledge claim, arguing that the mind is more transparently known than any bodily thing — a premise that phenomenological critics will reverse.

there is a weakness in my nature that means that I cannot always concentrate attentively on one and the same piece of knowledge... by careful and frequently repeated meditation, ensure that I remember this maxim
Descartes acknowledges a structural limit of the Cogito-grounded mind — the inability to sustain continuous attention — and prescribes meditational practice as a remedy, a tension later thinkers exploit.

Copernicus and the others who followed him... were able to begin to 'dis-identify' with that subjectivity and to view experience as though it were from an Archimedean standpoint some distance from oneself.
Edinger situates the Cartesian Cogito within a broader history of ego-consciousness achieving distance from participation mystique, framing it as a stage in the evolution of Western self-awareness rather than a logical problem.
