Philosophy Question from the 1600's

[SteelCitySouth]

This riddle was answered beginning in 2003. The answer is no. Those who had their sight restored, having been blind their entire life were not able to distigush between different object using sight alone. It wasn't until they had used both senses over time were they able to then begin to be able to learn how to do this using sight alone.
