Cognitive Science and The Philosophy of Mind
Q What is the focus of this blog?
A This blog will summarize articles, papers, and materials I have gone through that touch on the subject of Philosophy of Mind and how its presence lays important foundation for the development of general artificial intelligence.
The blog covers the following topics:
- What Constitutes The Philosophy of Mind

- Consciousness As A Weak, Strong, or Normal Emergence
- The Primal Instincts vs. The Unknown

- Computationalism and The Computational Theory of Mind
- A Turing Style Computational System
- The Computational vs The Representational Theory of Mind
- Computationalism vs Functionalism
- The Emergence of The Representational Theory of Mind
- What Are Syntactic Underpinnings?
- Tying Everything Together and Connecting The Dots
- In A Nutshell
Q What are “easy” and “hard” problems of consciousness?
A The easy problems involve understanding mechanisms of perception, attention, and behavior. The hard problem concerns subjective experience or qualia, which are deeply subjective and cannot be directly observed or measured.
Q What is fundamental property dualism?
A Fundamental property dualism regards conscious mental properties as basic constituents of reality, on a par with fundamental physical properties. This view is also referred to as panpsychism.
Q What are the hypotheses over the emergence and origin of consciousness?
A The hypotheses include strong emergence, weak emergence, and normal emergence. Each hypothesis offers a different perspective on how consciousness arises from physical processes:
- Strong Emergence: Higher-level properties that are fundamentally new and cannot be reduced to lower-level explanations. For example, consciousness itself might be considered strongly emergent, involving subjective experiences that cannot be directly deduced from neural activity alone.
- Weak Emergence: Higher-level properties that are unexpected but fully explainable by lower-level processes. For example, the behavior of a flock of birds can be explained by simple rules followed by individual birds, leading to complex patterns.
- Normal Emergence: Properties that arise predictably from underlying processes. For example, the temperature of a gas results from the average kinetic energy of its molecules, and this relationship is well-understood and predictable.
Q What is the Primal Instincts vs. The Unknown theory?
A This theory suggests that humans could perform tasks as automata without being aware of it, citing examples such as driving while talking and fight-or-flight responses.
Q What is the significance of consciousness according to Thomas Henry Huxley?
A Huxley believed that sensations and feelings are mere byproducts of the brain’s mechanics, and do not cause any behavior.
Q What is the "Nomological dangler" according to J.J.C. Smart?
A Smart argued that seeing consciousness as a purely physical process eliminates the need to explain the grey area of brain processes in a more scientific and established system.
Q What are the theories that address the mind-body problem?
A Theories include Type vs. Token Identity Theory, Eliminative Materialism, Functionalism, Neutral Monism, and Mind-Body Dualism. These theories offer different perspectives on the relationship between consciousness and the physical world:
- Type vs. Token Identity Theory: Proposes that mental states are identical to specific physical states or processes in the brain. Type identity theory suggests each mental state type corresponds to a specific physical state type, while token identity theory allows for different physical states across different instances.
- Eliminative Materialism: Suggests that current folk psychology and common-sense understandings of mental states, including consciousness, are fundamentally flawed and may be eliminated or revised in light of future scientific understanding.
- Functionalism: Defines consciousness in terms of functional roles within a system, emphasizing the causal relations between inputs, outputs, and other mental states. Consciousness arises from the functional organization of the brain.
- Neutral Monism: Proposes that consciousness and physical phenomena are different manifestations of a neutral substance or property underlying reality. Consciousness is neither purely mental nor purely physical but emerges from a more fundamental neutral substrate.
- Mind-Body Dualism: Posits that consciousness is a non-physical or immaterial aspect of reality. It suggests that consciousness exists independently of physical processes and may have properties that cannot be fully explained in terms of material phenomena.
Q What is Computationalism?
A Computationalism holds that the mind is a computational system similar to a Turing machine, and core mental processes are computations similar to those executed by a Turing machine.
Q What is a Turing-style computational system?
A A Turing-style computational system includes memory locations, a central processor, and a machine table that determines the processor’s actions based on its current state and the symbol it is accessing.
Q How does the Computational Theory of Mind (CTM) compare with the Representational Theory of Mind (RTM)?
A CTM focuses on computational processes, while RTM emphasizes mental representations and their connections to the external world. RTM addresses limitations of CTM by incorporating qualitative aspects of consciousness and flexible cognitive processing.
Q What are productivity and systematicity in CTM and RTM?
A1 CTM:
- Productivity: CTM explains the productivity of thoughts by assuming that the mind, as a computational system, can generate an infinite number of thoughts from a finite set of symbols and rules.
- Systematicity: CTM assumes systematicity by subscribing to the structural organization of thoughts and the systematic rules of inference that govern them.
A2 RTM:
- Productivity: RTM posits that a finite set of symbols in natural language can entertain an infinite number of logical propositions using a finite set of concepts and ideas.
- Systematicity: RTM highlights the inherent systematic relationships between basic cognitive constituents, facilitating coherent and structured thought processes.
Q What are the limitations of CTM?
A Limitations include the Symbol Grounding Problem, difficulty in explaining qualia and consciousness, and rigid rule-based processing that may not capture the flexible nature of human cognition.
Q What is Connectionism?
A Connectionism is an approach within cognitive science that emphasizes distributed processing and learning from experience, using interconnected units similar to neurons in the brain.
Q What is the significance of hybrid models in AI?
A Hybrid models integrate connectionist ideas with representational theories, combining symbolic manipulation capabilities with the learning and adaptability features of connectionism.
Q What are syntactic underpinnings?
A Syntactic underpinnings refer to the foundational principles and structures that dictate the formation of sentences and phrases in a language, including rules for word order, phrase structure, and grammatical categories.
Q What strategies can address syntactic underpinnings?
A Strategies include using grammar formalisms, developing parsing techniques, building rule-based systems, leveraging linguistic resources, and employing machine and deep learning approaches to learn syntactic patterns.
Q How does Connectionism address the limitations of CTM?
A Connectionism offers a dynamic, continuous representation of cognitive processes through interconnected units, addressing the rigidity and symbolic limitations of CTM by using distributed representations and learning from experience.
Q What is the main takeaway from this blog?
A The blog explores the Computational Theory of Mind (CTM) and its implications, addressing various theories on consciousness, the mind-body problem, and cognitive processes. It highlights the limitations of CTM and introduces Connectionism and the Representational Theory of Mind (RTM) as alternative approaches.
