Abstract

Suppose you are a blindsighted subject and an experimenter sitting opposite you says of an object in your functionally blind field ‘that peach looks delicious’. Unless you move your head to encompass the object within your normal field of vision you will not know which object she is talking about. Suppose now she reverts to the strategy used by neurophsychologists who work with blindsighted subjects and simply tells you that there is an object there and asks you either to reach for it or guess its shape, colour and so forth. If you are one of the well-trained blindsighted subjects who have been worked over for many years by psychologists you may well be able to do so, while denying you have any visual experience of the object and insisting you are only guessing. And, in concurrence with the existential formulation the experimenter now uses, instead of the demonstrative, it is natural to think that your singular reference, based on your perceptual input, is descriptive, as in ‘the object she maintains is there’ or ‘the object I am guessing about’ or ‘the object in my blind field’, etc.
