IB Philosophy 6.2.1 Cognitive Science and the Concept of the Self Notes

What Is Cognitive Science?

1. Cognitive science is an interdisciplinary field that draws on psychology, neuroscience, linguistics, artificial intelligence, and philosophy to study the mind and its processes.
2. Where philosophy of mind traditionally relied on conceptual analysis (breaking ideas apart to examine their logic) and thought experiments, cognitive science adds empirical data from brain scans, behavioural experiments, and computational models.
3. The central question linking the two fields is whether the traditional philosophical concept of the self can survive what neuroscience actually reveals about how brains generate experience.
4. Philosophers such as Patricia Churchland have argued that philosophy cannot afford to ignore neuroscience: our theories of mind must be constrained by what we know about the brain.
5. This connects directly to the Unit 6 overarching question of what differentiates science from non-science: cognitive science claims to study the self scientifically, but many philosophers question whether subjective experience can be captured by scientific methods alone.
6. Functionalism is one of the dominant theories in cognitive science. It says that what makes something a mental state is the job it does, not what it is physically made of. Your pain, for example, is whatever plays the functional role of pain: it gets triggered by damage, it makes you want to stop the hurting, and it influences your behaviour. That role could be played by neurons in a human brain or, in principle, by silicon chips in a computer.
7. Critics like John Searle respond that functionalism misses what matters most: the qualitative character (the “raw feeling” of an experience, like the specific sting of pain) of conscious experience, which no purely computational account can explain.
8. Today, we’re examining the tension between these approaches: cognitive science offers powerful tools for mapping the self; philosophy asks whether those tools are sufficient to capture everything the self involves.
9. Understanding how philosophy of mind and cognitive science relate is essential for evaluating the reductive explanations (attempts to explain the self entirely in terms of biology and chemistry) explored in topic 6.2.2, where the question becomes whether all aspects of human life can be reduced to biochemistry.
10. As you work through this material, keep in mind the demarcation problem: does cognitive science's reliance on empirical methods make its claims about the self genuinely scientific, or do some of its conclusions smuggle in philosophical assumptions that cannot be tested?

The Minimal Self and the Narrative Self

1. Cognitive science distinguishes between two layers of selfhood: the minimal self and the narrative self.
2. The minimal self is the immediate, pre-reflective sense of being a subject of experience (it arises before you consciously think about yourself), the basic feeling that this body is mine and these actions are mine.
3. Shaun Gallagher, a leading figure in this research, identifies two key components of the minimal self: sense of ownership (this hand is my hand) and sense of agency (I am the one moving it).
4. Neurological conditions like somatoparaphrenia (where patients deny that a limb belongs to them) reveal that ownership and agency can come apart, suggesting the minimal self is not a unified given but a construction of the brain.

The Narrative Self and Its Philosophical Implications

1. The narrative self is the richer, autobiographical sense of identity that emerges when we weave memories, intentions, and social roles into a coherent life story.
2. Daniel Dennett describes the narrative self as a "centre of narrative gravity", not a real entity inside the brain but an abstract point around which our stories about ourselves converge, much like a fictional character authored by the brain.
3. The distinction matters philosophically because the minimal self could exist without narrative. Newborn infants and patients with severe amnesia arguably possess a minimal self but lack a narrative one.
4. This raises a key objection: if the narrative self is a construction, could it be a useful fiction rather than something real? And if so, what grounds personal identity and moral responsibility, topics explored in 1.4.2 and 1.4.3?
