Remarks on the Philosophy of Psychology, Volume 1 (Remarks on the Philosophy of Psychology)

In one sentence

The "mental" is not a hidden, private theater of inner states; rather, "mental" refers to the public, observable ways in which we behave and speak.

Why read this (and who it's for)

This book is a foundational text for anyone who wants to understand the "linguistic turn" in philosophy. It solves the problem of mentalism—the assumption that there is a "ghost in the machine" (a private, inner life) that causes our actions.

It is for philosophers, cognitive scientists, and anyone who finds themselves asking, "What is my mind doing?" It will teach you to stop looking inward for the source of your thoughts and start looking at the structure of your behavior and the language you use to describe it.

The big idea

Wittgenstein argues against the "Cartesian" view of the mind. We often think of the mind as a private room where "mental events" occur, and that our bodies are merely the instruments of these hidden events. Wittgenstein argues this is a linguistic trap. When we say "I am thinking," we are not describing a private, internal sensation; we are describing a public, observable state of affairs.

The central thesis is that mental life is a public practice. To have a "mental" state is to be engaged in a specific type of behavior that is intelligible to others. If you cannot describe a mental state without referring to observable behaviors (like "he looks sad" or "she is solving a puzzle"), then the "mental" is not a separate, hidden entity—it is the behavior itself.

Wittgenstein wants us to see that the "inner" is not a place we go to; it is a way we speak. By analyzing the grammar of our psychological language, we realize that the "soul" or "consciousness" is not a thing to be discovered, but a way of organizing our experiences of behavior.

Key ideas

The Fallacy of the "Inner"

• What it is — The belief that mental states are private, internal occurrences that happen "behind" our behavior.
• Why it matters — If we believe the mental is private, we treat the mind as a mystery to be solved by "looking inside," which leads to a dead end because there is no "inside" to see.
• In the book — Wittgenstein argues that when we say "I am thinking," we are not referring to a hidden process; we are describing a state of being that is only meaningful in the context of our public interactions.

Behavior as the Primary Data

• What it is — The assertion that the only things we can actually know about "mental" states are the observable behaviors associated with them.
• Why it matters — It shifts the focus of psychology from "finding the soul" to "mapping the behavior." It forces us to admit that we only know the mind through the "outward" manifestations of the mind.
• In the book — He points out that we never "see" a thought; we see a person looking thoughtful, writing a note, or reacting to a stimulus. The "thought" is the label we give to the behavior.

The Grammar of Mental Life

• What it is — The idea that "mental" terms are part of a linguistic rule-game. We use words like "know," "believe," and "feel" because they have a specific function in our shared social life.
• Why it matters — It reveals that psychology is a branch of linguistics/philosophy, not a biology of the soul. To understand the mind, you must understand the rules of the language we use to describe it.
• In the book — Wittgenstein suggests that when we say someone "knows" something, we are describing their ability to perform a certain role in a social interaction, not a secret internal "light" of awareness.

The Illusion of Privacy

• What it is — The critique of the idea that "my" thoughts are somehow more private than "your" thoughts.
• Why it matters — It breaks the "solipsistic" trap. If my thoughts were truly private and inaccessible, I wouldn't be able to communicate them at all. The fact that I can communicate them proves they are not "private" in the way we think they are. -### The Role of Description
• What it is — The realization that "mental" states are actually descriptions of behavior.
• Why it matters — It simplifies the human experience. We don't need to invent a "hidden world" to explain why people do things; the description of the behavior is the mental state.
• In the book — He argues that when we describe a mental state, we are not "reporting" on a hidden thing; we are identifying a behavior.

Frameworks & tools

The Behavioral Mapping Method

To understand a "mental" state, stop trying to "feel" what the person is feeling. Instead, map the behavior:

1. Identify the Action: What is the person physically doing? (e.g., "He is staring at the screen.")
2. Identify the Context: What is the social/environmental rule? (e.g., "He is trying to solve a coding problem.")
3. Identify the Linguistic Label: What word do we use to describe this behavior? (e.g., "He is concentrating.")
4. The Synthesis: The "mental" state is the label we apply to the combination of action and context.

Memorable examples & stories

The "Inner" Room

Wittgenstein critiques the idea of a "private room" where the mind happens. He argues that if you were truly alone in a room, you wouldn't have a "mental life" in the way we think of it; you would simply be a body in a room. The lesson is that "mental" requires a public context.

The "Knowing" Rule

Consider what it means to "know" a fact. Wittgenstein suggests that "knowing" isn't a feeling of certainty; it is the ability to answer a question correctly in a specific social game. The lesson is that mental states are functional, not mystical.

The Description of "Thinking"

When we say someone is "thinking," we aren't looking at a brain wave or a soul; we are describing a person who is engaged in a specific type of behavior (like pondering). The lesson is that the "mental" is a shorthand for a complex set of behaviors.

Key quotes

• "The mental is not a hidden thing." (Paraphrased)
  • Why it matters: It strips away the mystery of the "soul" and forces us to look at observable reality.
• "To say that someone is thinking is to say that they are engaged in a certain behavior." (Paraphrased)
  • Why it matters: It defines the mental as a behavioral category, not an ontological one.
• "The 'inner' is not a place." (Paraphrased)
  • Why it matters: It destroys the metaphor of the mind as a container or a hidden interior space.

How to apply it

This week

• The Observation Exercise: When you see someone "thinking" or "feeling," stop and describe exactly what they are doing physically. (e.g., instead of "She's sad," say "She is looking down and her shoulders are slumped.")
• The Language Audit: Notice how often you use "internal" words (I feel, I think, I know) to describe things that are actually behaviors.

Ongoing

• Practice Behavioral Analysis: When analyzing your own behavior, treat your "mental" states as descriptions of your actions. If you can't describe the action, the "mental" state is likely a confused concept.
• Reject the "Ghost": Whenever you find yourself trying to "find" your thoughts as if they were objects in a room, remind yourself: "The thought is the behavior."

Common pitfalls

• The "Biological" Trap: People often think Wittgenstein is saying the mind is only neurons. He isn't. He is saying the meaning of the mental is found in the language and behavior, not just the chemistry.
• The "Nothingness" Trap: Some think he is saying there is "nothing" inside us. He isn't saying there is nothing; he is saying that the "mental" is not a thing—it is a way of describing how we act.
• Over-simplification: Don't mistake his critique of "mentalism" for a denial of experience. He isn't denying that you experience things; he is denying that those experiences are "private" objects hidden from the world.

Connects to

• Daniel Dennett's Consciousness Explained: Dennett takes a similar "functionalist" approach to the mind, though he focuses more on the brain's architecture than Wittgenstein's linguistic analysis.
• Thomas Nagel's "What Is It Like to Be a Bat?": Nagel argues for the "subjective" experience of the mind, which Wittgenstein would challenge by asking how that "subjectivity" can be described without referring to behavior.

If you remember only three things

• The "mental" is not a hidden interior; it is a public, observable behavior.
• "Thinking" and "Feeling" are labels for behaviors, not descriptions of hidden objects.
• To understand the mind, you must analyze the grammar of the language we use to describe it.

Internalize it

• Reflection questions

  • If I were alone in a room for a year with no one to speak to, would my "mental life" still be the same?
  • When I say "I am thinking," what specific behaviors am I actually describing?
  • How does my life change if I stop viewing my thoughts as "private objects" and start viewing them as "publicly intelligible behaviors"?

• Flashcards Q: What is Wittgenstein's primary critique of mentalism? A: The belief that mental states are private, internal events hidden from the world.

Q: How does Wittgenstein define "thinking"? A: As a description of a person engaged in a certain, observable behavior.

Q: What is the "Grammar" of mental life? A: The set of rules and social contexts that give meaning to words like "know," "believe," and "feel."

Q: What does Wittgenstein mean by "the mental is not a hidden thing"? A: He means that mental states are not "objects" located inside us; they are ways of describing how we behave and interact.

Q: Why is the "private room" metaphor for the mind problematic? A: Because it treats the "inner" as a place, whereas the "inner" is actually a way of speaking about behavior.

Fidelity note

This summary is based on the core philosophical arguments of Wittgenstein's Remarks on the Philosophy of Psychology. Because Wittgenstein's writing is notoriously dense and "dialectical" (he often writes in fragments to provoke thought rather than to provide a linear argument), some of his nuances regarding the specific "grammar" of certain words may be simplified here. Readers should be aware that Wittgenstein is not providing a "theory" of psychology, but rather a "critique" of how we mistakenly use language to create a fake psychology of the soul.
