Our mind has impeccable logic. The thought system of the Holy Spirit has impeccable logic. Everything which extends from God has impeccable logic. The metaphysics of the course is PERFECTLY logical. If something does not correlate logically it is false.
"The opposite of love is fear, but what is all-encompassing can have no opposite. Fear is the opposite of love. If love has an opposite it creates a state which does not exist." ergo.. logically... fear does not exist.
"He (God) did not make two minds, with Heaven as the glad effect of one, and earth the other's sorry outcome which is Heaven's opposite in every way. God does not suffer conflict. Nor is His creation split in two. How could it be His Son could be in hell, when God Himself established him in Heaven?" <--- this is perfectly logical. It means EARTH DOES NOT EXIST. "There is no world." ... if earth is opposite to heaven in every way and heaven (love) has no opposite, there is no earth. Period. This is METAPHYSICAL FACT.
Our mind has this capacity for perfect logic because it is perfect. However, when we are in the ego, the ego also USES our perfect logic to develop its entire thought system. Every single part of the ego's thought system is derived perfectly logically from an initial false premise.
All aspects of separation, the reason for the making of matter, the result of sickness and death, the making of an artificial world, all wars and conflicts, all dynamics of interpersonal relationships, all specialness and attack, is ALL - ABSOLUTELY ALL - based on a progression of IMPECCABLE LOGIC.
This world coming about and the arising of bodies and the invention of sickness and war and death can ALL be explained using nothing but logical statements. No interpretation or "fluffy glue" or fanciful ideas needed to make sense of it. It is all BLACK AND WHITE.
The belief that you are guilty because you sinned, is logic. The belief that your real sin affected God and therefore God is justified in a counter attack, is logic. The idea of denial is a logical split with entirely predictable logical consequences. Every consequence and result that has come about from the separation from God, can only happen ONE WAY and with ONE RESULT because it is all derived LOGICALLY.
If you can see the logic, you are seeing the METAPHYSICS.
"The ego has a purpose, just as the Holy Spirit has. The ego's purpose is fear because only the fearful can be egotistic. The ego's logic is as impeccable as that of the Holy Spirit because your mind has all the means at its disposal to side with Heaven or earth, as it elects. But again, let us remember that both are in you. In Heaven there is no guilt because the Kingdom is attained through the Atonement, which releases you to create. The word "create" is appropriate here because, once what you have made is undone by the Holy Spirit, the blessed residue is restored and therefore continues in creation."
