I would say that it depends upon whether your increased learning has opened your eyes to the infinite learning available to you. If it has, you are more wise, as you were less aware of the vastness of available learning when you "knew less." If, however, your increase learning has erroneously led you to believe that there is less for to learn than there was before, then you are less wise. Looked at as a function of the available knowledge of the universe, as that available knowledge goes to inifinity, the fraction of knowledge one has learned goes to zero.
Mathmatically... [my knowledge] / [total knowledge] = 0 when [total knowledge] = infinity
If you have not grasped, or cannot grasp the above then you are unwise regardless of your level of education.
"Educated" individuals fall on both ends of this spectrum.
A PhD was described to me once as "Imagine the the totality of human knowledge as a giant circle. Now, go the very edge of that circle and imagine an infinitesimal pimple sticking out from the circle. That is a PhD thesis."
Having earned a PhD myself, I think that this is a pretty good visual as it encompasses 2 critical aspects of a PhD. 1.) In the grand scheme of things, a PhD- by itself- is pretty meaningless. 2.) A PhD thesis should not exist within the bounds of current knowledge, but expands the boundaries of our collective understanding of the universe- in whatever field it is undertaken.
Put another way, a PhD is "learning more and more about less and less until you know everything about nothing..."
