Grasp, Mathematics, Logic

A grasp by a hand can completely contain an object.  Now, the process of Counting is not a transition from one item to another, but a cumulation.  In other words, a higher number contains a lower number.  Furthermore, a contained object can itself contain an object, in which case, the latter is also within a grasp.  So, derivable from physiological Grasp are both Mathematics, i. e. all operations are modes of Counting, and Logic, i. e. the fundamental pattern of which is: if A contains B, and B contains C, then A contains C.  Thus, what are traditionally classified as 'pure' mental processes can be derived from manual Grasp.
