Single Idea 7373

[filed under theme 15. Nature of Minds / B. Features of Minds / 7. Blindsight ]

Full Idea

Discussions of blindsight have tended to ignore just how paltry the information is that blindsight subjects glean from their blind fields.

Gist of Idea

Blindsight subjects glean very paltry information

Source

Daniel C. Dennett (Consciousness Explained [1991], 11.4)

Book Ref

Dennett,Daniel C.: 'Consciousness Explained' [Penguin 1993], p.342


A Reaction

This is a bit unfair, because blindsight has mainly pointed to interesting speculations (e.g. Idea 2953). Nevertheless, if blindsight with very high information content is actually totally impossible, the speculations ought to be curtailed.
