Form and Grasp

For most Philosophers, starting wth Plato and Aristotle, 'Form' may have a variety of meanings, but the fundamental one is Shape.  Now, Aristotle classifies Shape as a Common Sensible, i. e. it can be an object of any of the Senses.  However, he does not explain how any of them can be the source of the circumambience required to cognize, either via direct surface contact or via a synthesis of direct surface contacts, a solid object.  Instead, that source can only be Grasp, i. e. the enfolding hand.  Accordingly, if analogy is involved in the Knowledge of any Form, it can be only with the hand, not the eye.  Thus, Aristotle's likening of Mind as the Form of Forms, to the hand as the tool of tools, is more literal than he appreciates.
