Aristotle's Distinction of Act and Potency Is Not a Genus

Being is intrinsically analogical, consisting in a likeness of diverse proportions of actuality. Thomas affirms that metaphysics gives the principles to all the other sciences. Act is not act because it is joined to potency; manyness involves act as limited by potency. Finite, quiddity or essence is intelligible to us. The proper object of the human intellect is quiddity in corporeal matter.
