I think
Kant was speaking of what I define as the Involutionary Inward Path when he defined metaphysics as giving a sense of wholeness, like logic, but that it was a delusory wholeness. I think the real “delusory” here happens when the denoting or naming of wholeness, or God, like logic or mathematics, becomes the thing of belief, or the thing in itself. I disagree with Kant that the God-Within and the God-Without of metaphysics cannot be known, and I think also that the God Within and the God Without are real but are supermaterial or epiphenomenal. However, the God Within has to be defined as Half-Known because the God Within, or the Spirit-Will-Within, is not Godhood.
The Godhood reached in the Evolutionary Outward Path is a Real and the Supreme Object, or Objects, and not delusory, and here God In Itself is also supermaterial or epiphenomenal and can be reached by way of material and supermaterial evolution. This defines
theological materialism. Kant might define both the
Inward and Outward Path goals as necessarily delusory, but since we do not know God fully until we evolve to Godhood, this does seem to define a form of idealism.
The knower becomes the known when Godhood is reached, but not when the God Within is known, or more precisely, when the God Within is seen and Half Known. The God Within or the Half Known can be known outside of Western science (so far) through the methods of the mystics of the Inward Path of the Revealed Religions. What cannot be fully known by the subject is the Real Supreme Object Godhood, which requires that It/They be evolved to in the material and supermaterial world before It/They can be fully known, then the knower becomes the known as the Real Supreme Object.
A central “a priori” knowledge (prior to observation) exists in the Holy Spirit (the material Spirit-Will), or the Will to Godhood, which effects our knowledge of life, as well as effecting the direction of life. It is not really a “biased “ knowledge, the Spirit-Will just requires that we see some of its real world in a way that will best advance itself and us, since we are the vehicle of the Spirit-Will's advancement. It sees the Real World and it would not be able to successfully advance itself in evolution if it saw an unreal world. A bee or a bird sees its own version of the real world based on the same evolutionary needs, the world it sees is real but not the more complex world we see. I define the Soul as the Zenith of the Mind, and the Spirit-Will as The Zenith of the Soul.
This means we are determined---not biased---to see certain sections of the real world which are therefore not merely a delusory product of our phenomenal minds but are real. It is mind that essentially does this knowing however crude the mind may be. The greater the mind the greater the reality of the world is grasped.
Projecting this epistemology upward to when Godhood is attained at the Zenith of Evolution, Godhood would be able to see Complete Reality and not just these lower sections of reality as we see.
Theological materialism heals the division between faith and science because it heals the divisions between the spiritual and the material by defining the spiritual as supermaterial.
