An external thing that is knowable [is knowable] by means of something internal that is consubstantial [with the rational soul].
Nicholas of CusaSince beings desire to exist, because to exist is a good thing: they desire the One without which they cannot exist.
Nicholas of CusaThose, however, who saw that one cannot attain wisdom and perennial intellectual life, unless it be given through the gift of grace, and that the goodness of the Almighty God is so great that He hears those who invoke His name, and they gain salvation, became humble, acknowledging that they are ignorant, and directed their life as the life of one desiring eternal wisdom. And that is the life of the virtuous, who proceed in the desire for the other life, which is commended by the saints.
Nicholas of CusaNothing could be more beneficial for even the most zealous searcher for knowledge than his being in fact most learned in that very ignorance which is peculiarly his own; and the better a man will have known his own ignorance, the greater his learning will be.
Nicholas of CusaBut if you search further, you find in yourself nothing similar to God, but rather you affirm that God stands above all this as cause, origin, and the light of life of your intellective soul.
Nicholas of CusaFor our intellectual spirit has the power of fire in itself. For no other purpose is it sent by God to the earth than that it glow and grow into a flame. When it is excited by admiration, then it grows, just as if the wind entering into a fire excited its potential to actuality. If we apprehend the works of God, we marvel at eternal wisdom.
