Viral particles outside a host cell (so called virions) are inert entities with a genome surrounded by a protective coat.
Or do they merely represent an inert biological entity?
The two most important arguments against mathematical realism are the epistemological problem for platonism — how do we come by knowledge of causally inert mathematical entities?
On those earlier conceptions at least many properties are causally inert, other-worldly, abstract entities that exist outside space and time; they are timeless, necessary beings, and since we cannot come into causal contact with them, our knowledge of them is problematic.
Given that properties are abstract entities, and abstracta are causally inert, then God is abstract and causally inert — which is of course inconsistent with the core tenet of classical theism according to which God is the personal creator and sustainer of every contingent being.
Thus for Kant, the Newtonians regard space as an infinite substance-like entity that is imperceptible and causally inert, a view that Kant regards as absurd on general metaphysical grounds.

During the first half of the twentieth century, many scientists considered viruses the smallest living entities and primitive life forms somehow placed between the inert world and highly evolved cells.
The structure is related to that of serine/threonine protein kinases and the present study identifies that the Type VII secretion system exploits and re-uses a stable modular entity and fold that has evolved to participate in protein protein interactions in a similar fashion to the catalytically inert pseudokinases.
