Wisdom isn't knowledge that causes suffering for others; it is enlightened insight for improving one's own life as well as the lives of others.

Wisdom for Modern Life by Daisaku Ikeda

The SGI is a gathering of ordinary people. We struggle to ensure that the people are not despised and exploited by the powerful. To help all people become strong and wise, we are developing a network of peace and culture and putting great effort into education. By nature, the people are strong, wise, cheerful and warm. Religious faith has the power to draw out those qualities. The purpose of faith is not to turn people into sheep; it is to make them wise. Wisdom isn't knowledge that causes suffering for others; it is enlightened insight for improving one's own life as well as the lives of others.
