The 'motif' of Logic in Aristotle's corpus
The primacy of logic can be seen as a type of motif among Aristotle's arguments. Roughly speaking, the whole of Aristotle's corpus can be understood as his logical system applied to various schematic issues about existence. This is certainly the case with the Metaphysic which seeks to explain unseen systems in light of what we understand to be true. Things exist in the secondary realm, the physical one, because of the first causes, which we can understand in light of logic and proper causality. (This essential amounts to logical intergration, to draw a math analogy).
The symbolism of numbers and math
Math is a critical facet of philosophy because it involves logic applied to numerals. Sections Mu and Nu in the Metaphysics deal extensively with the ontology of math and whether or not numbers are symbols or not. Their inclusion as a symbol in this section is due to their representative nature in the Metaphysics.
The Unmoved Mover
This is perhaps one of the most literary figures in the otherwise very literal, terse work of the Metaphysics. The image of God offered is a reference to the belief that God was not caused by anything, but rather that God issues all causality as the source for existence and reason and cause and effect. This is a rather beautiful postulate about theology and a beautifully symbollic way to discuss God.
