  As in the previous line of reasoning, Gassendi seeks to establish that some properties of macro-sized objects—variable solidity here, immutable materiality in his first argument—require an underlying atomic architecture. Unfortunately, the atomic account offered by the present argument also is not necessary to explaining the macro-property—for we can still have diverse degrees of resistance to pressure even if the basic elements of matter also range in degrees of solidity. Worse still, this account is not even sufficient to the task. Given that atomic size and the amount of interparticulate void are also variable factors, different combinations of these structural characteristics could yield identical degrees of solidity across the otherwise very distinctive macro-level objects they compose. Then varying atomic architectures is not sufficient for varying degrees of resistance to pressure in objects on the macro scale.
