Single Idea 4049

[filed under theme 12. Knowledge Sources / B. Perception / 5. Interpretation ]

Full Idea

A unique yellow experience may be evoked with monochrome light of 580nm, or a mixture of 540nm and 670nm. ..Our interpretation of colour experience is a highly idiosyncratic artefact of our visual system.

Clarification

'nm' are nanometres. 'Idiosyncratic' means unique and unpredictable.

Gist of Idea

The way in which colour experiences are evoked is physically odd and unpredictable

Source

Alvin I. Goldman (Phil Applications of Cognitive Science [1993], p.117)

A Reaction

This confirms what I have always thought - that colour (as qualia) is strictly a feature of minds, not of the world.

6873 Coherent justification seems to require retrieving all our beliefs simultaneously [Goldman]
6874 Internal justification needs both mental stability and time to compute coherence [Goldman]
6875 Reliability involves truth, and truth is external [Goldman]
8831 Introspection is really retrospection; my pain is justified by a brief causal history [Goldman]
