i still like the D&D take to wisdom better. i think it pins it more accuratly.

in D&D intelect is the accumulation of knowledge. one with lots of intelect and no wisdom would likly be a wild mage. a person who knows a grate deal, but not nessacarily how to use what they know. one who has high wisdom but little intelect would be like the village idot who knows how to read ppl and to still get what they want.
(i read that some where and it stuck in my head)
so you can be wise without knowledg and it gives you the ability to read ppl and to know what it is they are saying even when they bumble their words and take too long or not long enough to say it.
