Single Idea 12579

[filed under theme 12. Knowledge Sources / B. Perception / 6. Inference in Perception ]

Full Idea

Perceptual experience has a second layer of nonconceptual representational content, distinct from immediate 'scenarios' and from conceptual contents. These additional contents I call 'protopropositions', containing an individual and a property/relation.

Gist of Idea

Perception has proto-propositions, between immediate experience and concepts

Source

Christopher Peacocke (A Study of Concepts [1992], 3.3)

Book Ref

A Reaction

When philosophers start writing this sort of thing, I want to turn to neuroscience and psychology. I suppose the philosopher's justification for this sort of speculation is epistemological, but I see no good coming of it.

Peacocke's account of possession of a concept depends on one view of counterfactuals [Peacocke, by Machery]
Peacocke's account separates psychology from philosophy, and is very sketchy [Machery on Peacocke]
Concepts are constituted by their role in a group of propositions to which we are committed [Peacocke, by Greco]
A concept's reference is what makes true the beliefs of its possession conditions [Peacocke, by Horwich]
Possessing a concept is being able to make judgements which use it [Peacocke]
A concept is just what it is to possess that concept [Peacocke]
Perceptual concepts causally influence the content of our experiences [Peacocke]
Perception has proto-propositions, between immediate experience and concepts [Peacocke]
An analysis of concepts must link them to something unconceptualized [Peacocke]
Most people can't even define a chair [Peacocke]
Consciousness of a belief isn't a belief that one has it [Peacocke]
Employing a concept isn't decided by introspection, but by making judgements using it [Peacocke]
