“All beings proceed from One First Cause. For either there is no cause of any being, or the causes of all finite things revolve in a circle, or the ascent (progression) is to infinity, and one thing is the cause of another, and the presubsistence of essence (cause) will in no respect cease. If, however, there is no cause of beings, there will be neither an order of things second and first, of things perfecting and perfected, of things adorning and adorned, of things generating and generated, and of agents and patients, nor will there be any science of beings. For the knowledge of causes is the work of science, and we are then said to know scientifically when we know the causes of things”.
~ Proclus ‘Metaphysical Elements”
