most touch receptors are present at the finger tips and as they are closer together, a more accurate result is identified by the brain ie there are two points, not one.
as the distance from finger tips increases, the number of receptors per unit area decrease, and the result identified by the brain is more inaccurate.

ok people start thanking me! :D :p
