Highlights from the Volume

2. Key Writings from Hilary Putnam
This section showcases Putnam’s foundational philosophical contributions, encompassing:Functionalism in Philosophy of Mind
- Putnam asserted that mental states are characterized by their functions, not merely by their physical configuration—similar to how a mousetrap can be constructed from wood or metal but still retains its identity through its operational role.
- He famously contended that "meanings aren’t confined to the mind"—implying that a term such as “water” derives its meaning from factors beyond our cognition, like the existence of actual H₂O. This aligns with the idea that the definition of “gold” is based not solely on our perceptions, but also on the tangible essence found in the environment.
- Putnam suggested that truth does not merely reflect reality, but functions instead as a lens that we adjust through collective human viewpoints—truth is what holds coherence within a given conceptual framework.
- In his later years, Putnam advocated for a moral realism that rejected the notion of ethics as entirely subjective, comparing moral evaluations to assessing the consistency of a narrative, similar to critiquing a book for inconsistencies and gaps.
