Merleau-Ponty's Conceptual Shift

1. The Major Shift: From Phenomenology to Ontology

The simplest way to frame the change between Phenomenology of Perception (1945) and The Visible and the Invisible (published posthumously in 1964) is as a shift in fundamental inquiry.

• Earlier Work (Phenomenology): Primarily focused on describing the structures of lived experience. The central question was, "What is it like to perceive the world as a lived body?"
• Later Work (Ontology): Focused on investigating the fundamental nature of Being itself that makes such experience possible. The question became, "What must Being be like for a world to appear to us at all?"

This is a move from describing the phenomena to questioning the ground of the phenomena. The following video provides an excellent initial overview of this shift.

As the video notes, while the arc of moving from a description of human existence to an inquiry into Being itself is similar to Heidegger's, the method is crucially different. For Merleau-Ponty, Being is not something accessed by turning away from appearances; rather, Being is the very "being of the phenomenon." This commitment to the perceptual world remains, but the nature of the inquiry deepens. Why did he feel this deepening was necessary?

2. Merleau-Ponty's Self-Critique

Merleau-Ponty did not see his later work as a refutation of Phenomenology of Perception, but as a project to bring its implications to their proper "ontological explication." However, this required a rigorous critique of the earlier work's limitations. He came to believe that, for all its innovations, Phenomenology of Perception had not fully escaped the philosophical tradition it sought to overcome.

The following reading from the Internet Encyclopedia of Philosophy details the core of this self-critique.

The core problems Merleau-Ponty identified in his earlier work can be summarized as follows:

1. It Remained a "Philosophy of Consciousness": Even though it described a body-subject engaged in the world, the philosophical analysis still often began from the position of a reflecting consciousness (the philosopher) looking at experience. This subtly presupposes the very subject-object distinction he wanted to dissolve. The analysis was about how objects present themselves to us, which keeps the "subject" pole of the dichotomy implicitly in place.
2. The Terminology Was Insufficient: As a consequence, terms like "body-subject," so central to Phenomenology of Perception, began to seem inadequate. This terminology is conspicuously absent from his later writings as he sought a language that was not tied to the concept of a "subject."

A Deeper Problem: The "Tacit Cogito"

Beyond this general critique, Merleau-Ponty pinpointed a specific, foundational concept from his earlier work that he now saw as "impossible": the tacit or pre-reflective cogito. This was the idea of a self or consciousness that exists before language and reflective thought—a silent, primordial awareness we could access through phenomenology.

In his later work, he realized this was a philosophical fiction. He concluded that the very act of thinking about a pre-linguistic self is, paradoxically, an act performed in language.

This next reading explains this crucial reversal in his thinking.

This is a profound shift. The attempt to "return to the things themselves" in a pure, pre-linguistic state is rejected as a "misplaced nostalgia." Instead, he recognizes that language and thought are interwoven with our being from the start. This move away from a philosophy of consciousness and the tacit cogito clears the way for a new kind of inquiry—one that doesn't start with a "subject" at all, but with the fabric of Being in which seeing, thinking, and speaking are already intertwined.

3. The New Direction: An Ontology of the Visible and Invisible

Having critiqued his prior starting point, Merleau-Ponty needed a new one. He finds it in what he calls perceptual faith: the undeniable, pre-philosophical reality that we are in and of a world that appears to us. The goal is no longer to explain how a subject can know an object, but to investigate the structure of this appearing itself.

This new ontology is an ontology of the Visible and the Invisible.

• The Visible: The sensible world, the realm of perception. It is continuous, whole, and primary.
• The Invisible: The world of thought, ideas, and language. It is not separate from the Visible but is its hidden lining or structure. It is often fragmented and secondary.

The video segment below introduces this new orientation.

This reorientation is radical. Philosophy, especially since Descartes, has traditionally begun with thought (cogito ergo sum) and then tried to prove the existence of the sensible world. Merleau-Ponty now insists we must start with the sensible world—the Visible—and understand thought—the Invisible—as something that emerges from it. This is the positive project of his late philosophy, for which he would develop new concepts like Flesh (chair) and the chiasm to describe the relationship between the Visible and the Invisible.

As the Stanford Encyclopedia of Philosophy article concisely puts it, the goal of The Visible and the Invisible is to "clarify the ontological implications of a phenomenology that would self-critically account for its own limitations." (Resource LINK, Section 1).

Conclusion

Today we have mapped the crucial turn in Merleau-Ponty's career: the movement from the phenomenology of perception to the ontology of Being. This was not an arbitrary change but a philosophically necessary one, driven by a rigorous self-critique.

Key Takeaways:

• The Conceptual Shift: Merleau-Ponty's work shifts from a phenomenology (describing lived experience) to an ontology (investigating the structure of Being that makes experience possible).
• Motivation for the Shift: He came to believe that Phenomenology of Perception, despite its intentions, remained a "philosophy of consciousness" that did not fully escape the subject-object dichotomy.
• Critique of the Tacit Cogito: A key element of his self-critique was the rejection of the "tacit cogito," the idea of a pre-linguistic self. He recognized that language and thought are integral to being, not later additions.
• The New Ontology: His later project is an ontology of the Visible (the sensible world) and the Invisible (the world of thought), which attempts to understand how the latter emerges from the former, reversing the traditional philosophical starting point.

Preview of the Next Lesson:

We have now established why Merleau-Ponty needed a new conceptual framework. In our next lesson, we will begin to explore that framework itself. We will tackle what is arguably the most important and difficult concept of his later work: the Flesh (chair). This is his term for the elemental fabric of Being, the shared medium in which the seer and the seen, the toucher and the touched—and the Visible and the Invisible—are intertwined.
