First define intelligence. Knowing yourself is a good thing. Intelligence indicates forethought, sensitivity, the ability to problem-solve among other things in general... but it can bring misery. Knowing yourself and having a far greater intelligence than others can become lonely, because there are as a rule few truely intelligent people and they are far between.

Those that choose to not be blind are certainly hated, as the blind resent those that see.... and how is the blind sure of what the seeing say about the physical world using their eyes? It's like a totally different world to someone who is a genius.

...but intelligence can also extend to those amiable souls who truely understand people and know them heart and soul, even when they have barely met them... perhaps they are not intelligent in the usual 'book-learning' way, but their social and personal wisdom is far greater.
