Single Idea 6644

[filed under theme 12. Knowledge Sources / B. Perception / 3. Representation ]

Full Idea

Computational psychologists object to the 'ecological' approach to perception (with its externalist, direct realist picture), because it leaves us entirely in the dark as to how our senses 'pick up' information about the environment.

Gist of Idea

Computationalists object that the 'ecological' approach can't tell us how we get the information

A Reaction

I find myself siding with the computationalists, but then I have always favoured the representational view of perception among philosophers. Lowe comments that both approaches neglect actual experience. We construct models, e.g. of London.
