Letters 89.4

In the first place, therefore, if you approve, I shall draw the distinction between wisdom and philosophy. Wisdom is the perfect good of the human mind; philosophy is the love of wisdom, and the endeavour to attain it. The latter strives toward the goal which the former has already reached. And it is clear why philosophy was so called. For it acknowledges by its very name the object of its love.
