I believe human intelligence is a characteristic of the mind, it stays with the soul, and its development is one of the important goals in each incarnation. From what I've read we are born with an IQ that doesn't suffer major fluctuations over one's life, under normal health circumstances. On the other hand I've watched a couple of documentaries, that presented cases when individuals that suffered major traumas acquired new and exceptional gifts in disciplines as mathematics, painting, music, for which they didn't show even some interest before. Is the brain only a limiting factor of our soul's intelligence, or more? I've noticed behavioural characteristics in some individuals that are similar to those of certain relatives from previous generations, not only parents, but aunts and uncles, grandparents, or further. Does the genetical inheritance play a role in the intelligence of an individual? Which and how?
