An old but interesting question

I'm going to steal a really good question and topic from the Philosopher's Zone for friday the 29th - "Molyneux's problem."

See, Molyneux was an Irishman from the 17th century. And when he wasn't busy keeping up with all things dealing with optics he read up on contemporary philosophers and medical journals.

"If a blind man were suddenly given sight, would he be able to differentiate a cube from a sphere by sight alone?"

Regardless of any given answer, the question is a powerful one. The type of question, in fact, that makes me love philosophy. Questions like the above opens the mind to channels of thought heretofore unexplored.

Therefore, an evening spent thinking over Molyneux's problem is an evening well spent.
