Late 16 century scientist William Molyneux proposed a philosophical problem (Per the Stanford Encyclopedia of Philosophy) he asked, "Suppose a Man born blind, and now adult, and taught by his touch to distinguish between a Cube, and a Sphere of the same metal, and close to the same bigness, so as to tell, when he felt one and the other; which is the Cube, which is the Sphere. Suppose then the Cube and Sphere where placed on a Table, and the Blind Man to be made to see. The Man would then only use his sight, before he touch'd them, would he be able now to distinguish, and tell, which is the Globe, which the Cube?" (Some words where changed to make it easier to understand the question since it was written in old world English)
