Christianity Dark Ages

The power the papacy grows and reaches its apex due to removal of older reigimes. Barbarian powers such as Lombards supplanted older emperors and took on different roles w.r.t. culture and faith. In the vicissitudes of state powers exchanged, the Church grew its authorities on faith as it took opportune moments assert its independence. However, authority wasn’t simply the command of the word but also a militaristic one (“Just war”) in the so-called defense of the institution. Ultimately, the great schism between east and western churches was the refusal of the former to submit to such an authority.

The scholastic philosophy that dominated this era (West) was the extension of Aristotle’s metaphysics and logic/dialectic. Western Christianity readily adopted the language and terms set established by their ancestors to define the nature of God. One of the earliest ontological arguments for existence of God was established by Saint Anselm; Russell quotes,
“We define God as the greatest possible object of thought. Now if an object of thought does not exist, another, exactly like it, which does exist, is greater.Therefore the greatest of all objects of thought must exist, since, otherwise, another, still greater,would be possible. Therefore God exists.”
The argument is a play on language where existence is used as a predicate.

Scholasticism culminated with the works of Saint Thomas Aquinas whose beliefs on the nature of God followed the metaphysics of Aristotle. God as actus puras (pure act) is identical with his essence which necessitates his existence; this is analogous to fusing both the Aristolean form and matter in their relation of potentiality and actuality. The existence of God follows from Aristotle’s “unmoved mover” or prime mover / first cause. Last, Thomas asserts that truth is derived from two sources: Natural reason or the logic of man from first principles is the first source. Divine reason or revelation by the grace of God is the second source. Moreover, the two bodies of knowledge derived from these sources can coexist (non-contradictory); this protected the many creeds issued by the Church in a retroactive sense.

schism

Outside of issue of papal authority, the great schism between Eastern and Western churches disagreed on the nature of the trinity of God. From the works of Aquinas, the Western church’s holy trinity (father, son, holy-spirit) belong to the essence of God and are all inter-related but impersonal; each Person is not an treated as an individual per-se but are distinguished via relations with one another. I liken the Father to the universal form of all ideas, the Son as God’s awareness of the forms (self-knowledge) through will/intellect, and the Holy-spirit as an archetypal conscience that is derived from a tension between universals and particulars. The Eastern church disagrees as they center the God head on the Father (personal) as the sole originator of both the Son and the Holy-spirit.

ockham

The end of the middle ages is marked by the rejection of universals and the regularization of concepts. William Ockham was a major proponent of this Nominalist movement by asserting that universals didn’t exist but are abstractions via intellect (bottom-up organization); universals are merely words. Ockham’s razor posited that entities should not be multiplied beyond necessity which is to say that solutions or explanations should be parsimonious or as simple as possible. Such a constraint will have a power effect on the enlightenment period where older assumptions are discarded/culled away and the scientific method for acquiring knowledge on nature can advance (in increments).

transmigration     forms

The Egyptian-Orphic concerns with the afterlife and Pythagoras’s mysticism led to a curious “wheel-of-fate” image representing reincarnation, a telos of the soul towards “the one”, and a commitment to a particular ascetic way of life. Socrates-Plato further differentiated the concept by separating soul from body and allowing the former to persist beyond corporeal existence for a time before returning (transmigrating and being later bound) to a body. In my conception (left), the soul is enlarged during life on earth via a way of living. In Plato’s world, this may be done by acquiring knowledge (“Ideas”) which are not from sensory impressions (that are distortions/illusions) but come from without (the mind/insight). This can be told in his “parable of the cave” but I render this by simply juxtaposing an ideal triangle (straight lines) to a perceived triangle (curves) (right).   

republic

Plato’s utopia or ideal society was influenced by Lycurgus’s Sparta but can be broken down into 3 class systems (guardians, soldiers, commoners) with distinct virtues (wisdom, courage, temperance). I summarize each of them as follows: Wisdom is penetrating thought and insight. Courage is a firm center surrounded by uncertainty. Temperance is the rejection of extremes. 

forms and matter    essence

Plato’s protege, Aristotle tried to clean up (remove) much of the former’s mysticism out of his concepts. Our impression of things are now derived from how “form” shapes “matter” in a teleological manner (left: circle into triangle). The incompleteness of ideas have been concretized into the notion of “essence” or the observed qualities that a thing must possess to be classified as such (right: 3 sides make a triangle).

govt

Aristotle’s politics were more practical than that of Plato’s Republic as he had enough sense to recognize power dynamics inherent in the tension between body (material) and soul (ideals). Here I signify the relations in terms of where power is concentrated (central v.s. egalitarian) and the form of the relation (material v.s. ethics).

logic

Last, we have Aristotle’s syllogistic logic which I summarize in terms of venn-diagrams. See the concept map for more elaboration.
