Summary

It is often not easy to explain to a layperson why recognizing objects is a non-trivial problem, since we seem to solve it so easily by simply looking at the objects. But suppose we were born blind and learned to distinguish between a cube and a sphere through our sense of touch. Then after an operation in which we would have regained sight, could we tell which is the cube and which is the sphere by simply looking and without touching? This thought experiment, which has preoccupied philosophers such as Locke and Molyneux, makes it clear that seeing and recognizing are not easy problems.

The 1st and 2nd edition of the article was written by Heinrich H. Bülthoff and Alexa I. Ruppertsberg.
