Hrm. I've never played with Psionics before, so we could say that neither has my character. And if he has never dealt with them before, it's something new to learn.
Also, it is easier to gain access to those in power when you have power yourself. He could wait 50 years until he is head of the monastry or whatever, but if he thinks that by helping this group of Psions he could gain renown which can be turned into leverage, he will. Renown is useless. But the power it grants him, to get at those in power and maybe get them to listen to him, could be very useful indeed. Having the king and councils make education compulsary would go a LONG way towards increasing the learning of the people.
