Course VIII - Teaching 13: Affirmative Negation

He who wishes to take the spiritual life will not achieve it if his mind does not change attitudes before knowledge of life and before his relation with the rest of individuals and their beliefs.
Usually, our mind sustains some few things known, already determined, experimented and proved, and feels quite proud and content with such supremacy.
Our mind merely affirms in the magnetic field of its knowledge, while systematically negates all that is outside this field.
So, our mind solves any metaphysical problem by faithfully using some few unknown postulates of its creed, calls these postulates “truth”, negates all postulates of other creeds a priori and even discards their partial consideration.
If one faith negates another faith without any cause, this is merely because of bad intention; only right intention leads to knowledge of the truth.
Our mind can penetrate into the secret of a thing unknown only by assuming an attitude of affirmative negation.
No negation is possible, since true knowledge adds to an imperfect knowledge what is indispensable to complete it.
Our mental attitude of affirmative negation is a state of expectation and good will to know what we do not know. Moreover, he who does not negate a knowledge because he does not know it, even now is affirming it potentially, and remains mentally in tune with extant possibilities to grasp and know it.
An affirmative negation contains potential knowledge of the universe.
