Why do we need the cognitive level in addition to the biological level?

• A. Mental states and processes are defined functionally, not anatomically
• B. Mental states are defined anatomically
• C. It is identical to the biological level
• D. It has no relation to the brain

Answer: (A)

Mental states and processes are defined functionally, not anatomically. The cognitive level asks what a mental state does—the input it responds to, the internal states it interacts with, and the output it produces—rather than where it sits in the brain or which tissues are involved. This functional view lets us describe thinking in terms of roles and causal relationships, which can be realized by different neural hardware. In other words, the same belief or goal can be implemented by different brain structures across people, species, or even artificial systems, as long as the functional pattern remains the same. That multiplicity of realizations is why we need a cognitive level separate from the biological level: it captures the abstract processes that generate behavior, not just the physical substrate that supports them. The other options imply mental states are fixed to anatomy, identical to brain biology, or unrelated to the brain, which would ignore the essential way cognition depends on functional organization and brain involvement.
