Wisdom is the right use of knowledge. To know is not to be wise. Many men know a great deal, and are all the greater fools for it. There is no fool so great a fool as a knowing fool. But to know how to use knowledge is to have wisdom.
In the spiritual world ... he will be wise who courts acquaintance with the most ordinary and transparent facts of Nature; and in laying the foundations for a religious life he will make no unworthy beginning who carries with him an impressive sense of so obvious a truth as that without Environment there can be no life.

If you lack knowledge, go to school. If you lack wisdom, get on your knees! Knowledge is not wisdom. Wisdom is the proper use of knowledge.
