Pleasure is the source of wisdom:

The feeling of pleasure is not only higher than wisdom, but it serves as the root and source of wisdom. When a person comes up with a new discovery in an intellectual matter, he becomes filled with joy. The reason that he feels this joy is because the newly discovered wisdom has freshly derived from his feeling of pleasure, and hence he currently enjoys the pleasure that is involved with its discovery. However, after time passes he no longer feels this pleasure in the new concept and discovery, as the time lapse has allowed the discovery to become distanced from its source in pleasure.
