Divine light surpasses human understanding; God’s presence is incomprehensible yet knowable, if only negatively: if creatures are mutable, God is immutable.

Plato’s Philosophy: Theory of Forms, Knowledge, and the Ideal State
Outlines the three main constituents of the universe. The cosmos, according to Plato, originates from order, not disorder.

Soil Factors
The bedrock is the mineral substrate from which the soil is formed, affecting its color, texture, structure, permeability, and acidity.
The climate is the most influential factor in pedogenesis. Rainfall supplies water for biological activity and chemical leaching or dissolution, dragging items from the topsoil. Soil can be zonal (closely linked to climate) or azonal (related to factors other than climate).
The topography also influences soil composition: plain areas accumulate coarse
