Repulsion and Solidity

The thesis that all Matter is a product of Attraction and Repulsion is difficult to reconcile with the ordinary experience of 'solid' objects.  However, that the 'subject' of experience is actually an agent, i. e. is itself constituted by repulsive and attractive forces, transforms 'solidity' into another repulsive force, i. e. to a resistance to the repulsion of an agent.  In other words, 'solidity' is what Kant calls an 'appearance', i. e. it has no subsistence independent of the context of the interaction of two repulsive forces, even if Kant's failure to completely re-conceive Subjectivity as Agency prevents him from similarly re-conceiving Appearance as the product of Dynamic interaction.  Likewise, if Locke had conceived his subject of experience not as a passive slate, but as constituted by dynamic Primary Qualities, he might have arrived at a concept of Secondary Qualities as resulting from the interaction of subjective and objective Primary Qualities.
