Just as any knowledge of the taste of something we have never actually tasted is quite empty until we do taste it, so the taste of this wisdom cannot be acquired by hearsay but by one's actually touching it with his internal sense, and then he will bear witness not of what he has heard but what he has experientially tasted in himself. To know of the many descriptions of love which the saints have left us without knowing the taste of love is nothing other than a certain emptiness. Thus it is that it is not enough for him who seeks after eternal wisdom to merely read about these things, but it is absolutely necessary that once he discovers where it is by his understanding he make it his very own.

(Nicholas of Cusa)
