 Taurellus develops some further considerations against understanding subsistence dependence in terms of the emanation of the essences of natural beings from the essence of God. Suppose that the heavens are preserved by means of continuous creation or by means of a perpetual efflux of divine essence. In this case, Taurellus argues, Heraclitus’ view of the perpetual flux of all things would be confirmed since nothing would remain intact beyond the duration of a moment. If emanation is thought of as a “flow” of essence, as much essence as is conveyed to a particular object at a given moment has to be previously withdrawn from its source (KOS: 235–236). In this way, emanation of essence implies the constant change both of created things and their source. Taurellus argues that such a conception of the mutability of all created things is contrary to the Aristotelian conception of the regular and stable motions of the stars—motions which become inexplicable once one assumes that stars are unstable and momentary objects. The same holds, according to him, for the fixed and stable figure of stars (KOS: 236).
