How charming is divine philosophy!
  Not harsh, and crabbed, as full fools suppose,
    But musical as is Apollo's lute...

                Milton, Mask of Comus (l. 476)

Nicolas of Cusa

Wisdom is not to be found in the art of oratory, or in great books, but in a withdrawal from these sensible things and in a turning to the most simple and infinite forms. You will learn how to receive it into a temple purged from all vice, and by fervent love to cling to it until you may taste it and see how sweet That is which is all sweetness. Once this has been tasted, all things which you now consider as important will appear as vile, and you will be so humbled that no arrogance or other vice will remain in you. Once having tasted this wisdom, you will inseparably adhere to it with a chaste and pure heart. You will choose rather to forsake this world and all else that is not of this wisdom, and living with unspeakable happiness you will die.

De sapientia; Dolan, 1962
