what is his stand on the manifest-scientific image compatibility
ChatGPT said:
James W. Cornman took a moderately reconciliatory stance on the compatibility of the manifest image and the scientific image—a conceptual division introduced by Wilfrid Sellars.
Let’s break this down:
Background: Sellars’ Distinction
- Manifest Image: The world as it appears to us—common-sense experiences, intentions, values, persons, etc.
- Scientific Image: The world described by scientific theory—atoms, molecules, fields, forces, etc.
Sellars argued these are not fully compatible, and that philosophy should aim to fuse them into a unified view.
Cornman’s Position
Cornman broadly agrees with Sellars’ framework, but he’s less pessimistic about integrating the two images. In his work—especially in Perception, Common Sense and Science (1975)—he explores how the scientific image can reinterpret, rather than replace, the manifest image.
Key Points of Cornman’s View:
- Epistemic Caution but Optimism:
- He acknowledges the tension between the two images but argues that science need not completely discard the manifest image.
- Scientific theories can explain why the manifest image appears as it does (e.g., perceptual illusions) without denying its utility or reality.
- Phenomenal vs. Theoretical Reality:
- Cornman sees phenomenal experience (how things appear to us) as real and worthy of explanation, not just illusion.
- Science, in his view, can explain the mechanisms behind appearances while still validating the role of appearances in guiding action and belief.
- Reinterpretation, Not Elimination:
- The manifest image may be reinterpreted in light of science (e.g., the table is not solid but made of atoms), but it isn’t eliminated.
- He aligns with a kind of constructive realism, where the manifest image is still important for human understanding and moral life.
- Bridge via Perception and Language:
- In his work on perception, Cornman tries to show that sense-data theories and scientific realism can be compatible through a careful analysis of how language and experience interact.
In Summary:
| Aspect | Cornman’s View |
|---|---|
| Compatibility of manifest and scientific image | Partially compatible through reinterpretation |
| Attitude toward manifest image | Respects and preserves its role in daily life |
| Role of science | Explanatory and interpretive, not eliminative |
| Alignment with Sellars | Agrees on the distinction, but more optimistic about synthesis |

was he an emergentist
ChatGPT said:
James W. Cornman was not an emergentist in the traditional or strong metaphysical sense, but he did explore views that interacted with or resembled aspects of emergentism, particularly in his work on materialism and mental states.
Let’s clarify what this means:
What Is Emergentism?
Emergentism is the idea that:
- Higher-level properties (like consciousness or mental states) arise from lower-level physical systems (like neurons),
- But these properties are not reducible to, nor fully explainable by, those lower-level components.
- There are “emergent laws” or causal powers that operate at higher levels.
So, a classic emergentist would say that while the brain gives rise to the mind, the mind has genuinely new properties that are not predictable or deducible from brain activity alone.
Cornman’s View: Materialism with Nuance
In his 1971 book Materialism and Sensations, Cornman defends a version of materialism (or physicalism), but one that tries to accommodate the reality and explanatory importance of mental phenomena.
Key aspects of Cornman’s view:
- Rejects Dualism:
- Cornman is committed to materialism—he does not believe in non-physical minds or souls.
- All phenomena, including mental states, ultimately depend on physical processes.
- Mental States Are Real:
- He doesn’t reduce mental states to mere behaviors or brain states in a simplistic way.
- He acknowledges the qualitative, subjective character of sensations (what philosophers call qualia) and tries to explain them within a materialist framework.
- Emergentist Flavor (without full commitment):
- While he stops short of strong emergentism, Cornman is open to the idea that mental properties may supervene on physical ones in non-reductive ways.
- He seems sympathetic to non-reductive materialism, where higher-level phenomena (like consciousness) depend on but are not identical to physical processes.
- Explanation Through Correlation, Not Reduction:
- He suggests that a one-to-one correlation between physical and mental states may be enough for explanation—even if reduction isn’t possible.
- This is more conservative than emergentism but not eliminative of the mental realm.
Conclusion:
Cornman was not a strong emergentist like C.D. Broad or Samuel Alexander.
But he was also not a reductive physicalist in the strictest sense.
He occupies a middle ground:
A materialist who recognized the autonomy and explanatory importance of mental phenomena,
With a position that might be best described today as non-reductive physicalism or “emergentist-leaning materialism”.
Would you like a comparison between his view and someone like Jaegwon Kim (who critiques emergentism), or between Cornman and modern thinkers like David Chalmers or Thomas Nagel?

compare to all three
ChatGPT said:
Excellent — let’s compare James W. Cornman to Jaegwon Kim, David Chalmers, and Thomas Nagel in terms of their views on mind-body relations, emergence, and materialism.
Overview of Philosophers
| Philosopher | Core Orientation |
|---|---|
| James W. Cornman | Moderate non-reductive materialist |
| Jaegwon Kim | Initially non-reductive, later shifted to reductionist physicalism |
| David Chalmers | Property dualist, coined the hard problem of consciousness |
| Thomas Nagel | Non-materialist realist, critiques reductive materialism, seeks a more inclusive naturalism |
Key Issues Compared
1. Mind–Body Problem
| Philosopher | View |
|---|---|
| Cornman | Mental states are real and physical, but not reducible in a straightforward way; likely a non-reductive materialist |
| Kim | Early support for non-reductive physicalism, but later rejected it for creating causal overdetermination; turned toward reductive physicalism or eliminativism |
| Chalmers | Argues physicalism can’t explain consciousness; proposes naturalistic dualism (physical + non-physical properties) |
| Nagel | Consciousness cannot be captured by current physical theories; proposes a future, expanded conception of science |
2. Emergence
| Philosopher | View |
|---|---|
| Cornman | Open to weak emergence: mental properties depend on physical but are not reducible; avoids full-blown emergentism |
| Kim | Strongly critical of emergentism: says it leads to unacceptable causal closure problems unless emergent properties reduce to physical ones |
| Chalmers | Supports naturalistic property dualism: conscious experience is a fundamental feature of the world, potentially emergent but non-reducible |
| Nagel | Suggests that emergence may be needed, but only as part of a radical expansion of natural science to account for subjective experience |
3. Consciousness and Qualia
| Philosopher | View |
|---|---|
| Cornman | Accepts the reality of qualia, tries to fit them into a materialist system via correlation and explanatory integration |
| Kim | Skeptical of non-physical qualia; saw mental causation as problematic in non-reductive frameworks |
| Chalmers | Qualia are irreducible; argues no physical account can explain why brain processes feel like anything |
| Nagel | Famous for “What is it like to be a bat?”; qualia show the limits of objective science in capturing subjective experience |
4. Attitude Toward Science and Reduction
| Philosopher | View |
|---|---|
| Cornman | Science can reinterpret the manifest image but should preserve mental phenomena |
| Kim | Committed to physicalist reduction to preserve causal efficacy of the mental |
| Chalmers | Science must be supplemented with new principles (e.g., psychophysical laws) |
| Nagel | Existing science is incomplete; proposes a new naturalism that can account for consciousness, value, and meaning |
Summary Table
| Feature | Cornman | Kim | Chalmers | Nagel |
|---|---|---|---|---|
| Ontology | Physicalist | Physicalist | Dualist (naturalist) | Non-materialist realist |
| Emergence | Soft/weak emergence | Rejects strong emergence | Accepts | Accepts or suggests |
| View on Qualia | Real, physicalistically interpreted | Problematic unless reducible | Irreducible | Irreducible |
| Reductionism | Rejects strict reduction | Favors reduction | Rejects reduction | Rejects reduction |
| Mental Causation | Compatible with physicalism | Problematic in non-reductive views | Needs new principles | Requires expanded science |
| View on Science | Can expand to include mind | Must preserve causal closure | Needs new fundamental laws | Needs broader conception |
Final Verdict on Cornman in Context
- Cornman is less radical than Chalmers or Nagel and more cautious than Kim.
- His position predates the hard problem discourse but grapples with similar tensions.
- He seeks to preserve the reality of mental experience without abandoning materialism, making him an early voice in what would become the non-reductive materialist camp.
- Unlike Chalmers and Nagel, he trusts science’s explanatory potential more, though not to the point of eliminativism like Kim leaned toward.
