The history of philosophy from the Ancient Greeks until now has mostly been an oscillation between - or attempt to find a middle-way, a compromise, between - two extremes; which have various labels but any choice of these two extremes always runs into the same problems.
One is that this is (or was) a single and unified reality (monism); which has either apparently split into a multiplicity - or else people have the illusion that it has split. Unity is ultimate, variety is merely temporary, or an illusion. One God created everything from nothing, The principle of the universe is order - chaos is contained within order, order will prevail. We Men are pieces of God, seeds, droplets from a divine ocean - but everything we are is Of God. Everything In Total is Good - and evil is temporary, a transitory kind of imbalance. God is omniscient and omnipotent. This mortal life is - by comparison with divine unity - utterly insignificant, and cannot affect anything that is eternal.
The other extreme is that which supposedly derives from Heraclitus: everything flows, everything changes, order and stasis are temporary and illusory; ultimately chaos rules. All 'understanding' is temporary, contingent, or merely delusional. There is no purpose or meaning to reality - it Just Is. There is no God. This apparent mortal life is everything - but it is nothing, really... a succession of subjective impressions merely. The are no real values: no truth, beauty or virtue - neither good nor evil.
By my understanding, neither of the above traditional extremes offer any meaning or purpose for this mortal life; nor do they provide a solid basis for our individual freedom or creativity, nor for the reality of both good and evil.
I regard Christianity as having become trapped by the metaphysical assumptions of monism, in opposition to the chaos which it regards as the only alternative. As a result, Christianity - as taught and exemplified by Jesus Christ, and described especially in the Fourth Gospel - has been distorted into a pre-existing monist framework which really does not make sense. Although by complexification and mystification - and by the false dichotomy with chaos (regarded as the only alternative) - an illusion of sense can be made and sustained by diktat, threats and authority.
Yet there is at least one metaphysical alternative to the above two, and that is the metaphysics to which I have adhered for about the last decade. This begins with the existence of beings in the midst of chaos, and has God as the creator, and creation as the making of a world of harmony between beings, aiming at greater freedom, hence greater consciousness; and always increasing creativity.
This harmony of beings is love - analogous to the love within an ideal family; and it can be understood as shared creative purposes and the mutual accommodation and help which is the consequence of love.
Therefore is the two classic and traditional views are monism and chaos; then this third view is rooted in creation. We began with chaos as a background, but with innumerable beings already existing. Creation began with God, and it was God who made possible the cooperation (harmony) between beings that began to change the universe.
Reality is neither and ultimate order, nor is it disorganized randomness; but reality changes, evolves, develops through time - and towards increasing love, harmony, purpose, meaning. This changes happens by the development of beings, under the influence of God. Initially being can passively be raised towards greater consciousness, by adding to their equipment
The advantages I find, up-front, are that it explains the origins of evil in chaos, the nature of evil in opposition to the Good; the nature of Good in God's creation - and the movement through time from evil towards Good: as God began with a chaotic universe and then made Heaven, and (since the work of Jesus Christ) began to people heaven with those beings who chose to subscribe to the project of Good. Thus it also explains the work of Jesus Christ, and accounts for his essential role in the divine project.
It accounts for the reality of freedom in our independent eternal origin as beings; the spiritual war whereby beings (such as ourselves) choose either the side of God and divine creation; or else to oppose that. It makes sense of the possibility of beings such as ourselves becoming genuine co-creators (ie, bringing something new, additional to God) in the creation that God began.
It provides a model for the meaning and purpose of this mortal life - its meaning in love which is working with the divine harmony, and acts of co-creation (even in this mortal life, but more so in resurrected eternal life); and as a time for learning and preparation for immortality to come.
So far, this metaphysics of creation has proved itself absolutely solid in response to the tests and critiques of my interrogations and life-experiences.
But this third metaphysics seems not to be understood by the adherents of Christian monism, or chaos; and the reasons is that they do not follow the implications of their metaphysics to their conclusions; but instead introduce 'unprincipled exceptions' or 'auxiliary hypotheses' so as to provide a pseudo-rationalization for (in particular) the meaning of mortal life and the reality of freedom.
These incoherent elements serve to take away the demand for something different; yet they fail to solve the incoherences that have been evidence for thousands of years, and are so obvious to adherents of the opposite views. I mean, the incoherence of traditional Christian metaphysics is obvious to evil-atheist-'materialists', and vice-versa.
The metaphysics of creation is only seldom held explicitly and consciously; yet I regard it as essentially the simple, instinctive, innate metaphysics of childhood (and, probably, ancestral hunter gatherers) that has been raised to a higher level of conscious awareness.
It is the metaphysics of the Fourth Gospel ('John') - and implicitly what Jesus lived and taught - and completed by his opening of Heaven to Men.
