Lewis

"The intellectual life is not the only road to God, nor the safest, but we find it to be a road, and it may be the appointed road for us. Of course it will be so only so long as we keep the impulse pure and disinterested; we may come to love knowledge -- our knowing -- more than the thing known: to delight not in our talents but in the fact that they are ours, or even in the reputation they bring us. Every success in a scholar's life increases this danger. If it becomes irresistible, he must give up his scholarly work. The time for plucking out the right eye has arrived. "
