Molyneux's Problem. This was a question posed to Locke whether a person born blind and who knew shapes by feel (cubes, spheres, etc.) would be able to identify those shapes without touching them if they suddenly gained the power of sight. It's basically a question of how unified our senses are, whether we can take information from one source input and draw conclusions from other sources. It's one of those issues where empirical observation -- science -- can step in and solve the problem. Turns out the answer is no.
