A Course in Miracles is perfectly logical

Each thought system starts with a logical premise, which determines everything that comes from it, which are perfectly logical conclusions. This is true of both God’s creation and the EGO’s world, which are logical outcomes.

The separation from God followed NEAT, LOGICAL steps. The thought system of the ego is run by impeccable logic, just as God’s thought system is. The outcome of each system depends entirely on its logical premise. At the CORE of A Course in Miracle’s metaphysics is PURE LOGIC.

If you can understand the logical premise of each system, and if you can follow the progression of logical conclusions based on that premise - which is IMPECCABLE LOGICAL REASONING, you will correctly understand ALL of the metaphysics of the course. Where everything fits. The TRUTH about the entire separation from God, states of awareness, what is true and false, what is real or unreal, who created what, how the systems MUST function etc.

It is all TOTALLY LOGICAL. If you struggle with logical reasoning you may have difficulty SEEING the logic or following it.

This literally means, that states of mind, states of separation, the making of the body and the world, all of the mechanics of special relationships, sin and death, the nature of the physical universe and its laws, ALL OF IT, is a LOGICAL CONCLUSION. Correctly discerning what the logic IS, HOW it progressed, and WHY that makes SENSE, is the key to accessing the core metaphysics in the course. Once you do this, you can refer to this metaphysics as a cheat-sheet, a reference to TELL YOU, what ANY statement in the course MUST MEAN, where it fits, and what JESUS MEANS. GUARANTEED.

"T-23.II.21. From the belief in sin, the faith in chaos must follow. 2 It is because it follows that it seems to be a LOGICAL CONCLUSION; a valid STEP IN ORDERED THOUGHT. 3 The steps to chaos DO FOLLOW NEATLY from their starting point. 4 Each is a different form in the PROGRESSION of truth's reversal, leading still deeper into terror and away from truth. 5 Think not one STEP is smaller than another, nor that return from one is easier. 6 The WHOLE DESCENT FROM HEAVEN LIES IN EACH ONE. 7 And WHERE YOUR THINKING STARTS, THERE MUST IT END."

"The ego's LOGIC is as IMPECCABLE as that of the Holy Spirit, because your mind has the means at its disposal to side with Heaven or earth, as it elects."

"The Holy Spirit USES LOGIC as easily and as well AS DOES THE EGO, except that His CONCLUSIONS are not insane. 5 They take a direction EXACTLY OPPOSITE, pointing as clearly to Heaven as the ego points to darkness and to death. 6 WE HAVE FOLLOWED MUCH OF THE EGO’S LOGIC, and have SEEN ITS LOGICAL CONCLUSIONS. 7 And having seen them, we have realized that they cannot be seen except in illusions, for there alone their seeming CLEARNESS seems to be clearly seen. 8 Let us now turn away from them, and follow the SIMPLE LOGIC BY WHICH THE HOLY SPIRIT TEACHES the SIMPLE CONCLUSIONS that speak for truth, and only truth."

"The Kingdom is the RESULT OF PREMISES, JUST AS THIS WORLD IS. 2 You may have carried THE EGO’S REASONING TO ITS LOGICAL CONCLUSION, which is total confusion about everything. 3 If you really saw this RESULT you could not want it. 4 The only reason you could possibly want any part of it is because you do not see the whole of it. 5 You are willing to look at the ego's PREMISES, but not at THEIR LOGICAL OUTCOME. 6 Is it not possible that you have done the same thing with the premises of God? 7 YOUR CREATIONS ARE THE LOGICAL OUTCOME OF HIS PREMISES. 8 His THINKING has established them for you. 9 They are exactly where they belong. 10 They belong in your mind as part of your identification with His, but your state of mind and your recognition of what is in it depend on what you believe about your mind. 11 Whatever these beliefs may be, they are the PREMISES that will determine what you accept into your mind."

"Look calmly at the LOGICAL CONCLUSION of the ego's thought system and judge whether its offering is really what you want, for this is what it offers you. 2 To obtain this you are willing to attack the Divinity of your brothers, and thus lose sight of yours. 3 And you are willing to keep it hidden, to protect an idol you think will save you from the dangers for which it stands, but which do not exist."

"In one sense the ego's fear of God IS AT LEAST LOGICAL, since the idea of Him does dispel the ego."
