No doubt that the speaking (rational) species of the [genus] animal is distinguished from the non-speaking (irrational species) by a power, through which it is enabled to imagine things rational, which power is called the speaking (rational) soul; and the custom has obtained of calling it the “hylik” mind, that is to say the potential mind, thus likening it to the hyle, which is potential matter.[J] Moreover this power is found in the whole human species; and it possesses in itself at the outset none of the mentally-grasped forms, but these arise within it after two sorts of processes: The first is through a Divine guidance, without effort of study, and without profitting from the senses, as for example the mentally-grasped self-evident axioms, like our conviction that the whole is greater than the part, and that two contradictories (contrasts) do not come together at one time in one and the same thing; so that sane-minded adults share equally in the acquisition of such forms. The second sort of process is through earning [the mental thought or truth] by reasoning process, and by array of proof and demonstration, such as the conception of logical truths, like genera, species, differentia, and properties, simple terms, and terms compounded in the various modes of compositions [of several ideas into one composite term], justly-moded syllogisms both valid and false, propositions which if moded into syllogisms lead to necessary demonstrated results, or to argumentative probable results, or to equally balanced rhetorical results, or to primary (axiomatical) sophistical results, or to impossible poetical results;[15] and such mentally-grasped forms as the recognition of the certainty of natural realities, like hyle (primitive matter) and form, privation (non-existence) and Nature, place and time, rest and motion, bulky bodies of the sky-firmament and bulky elemental bodies, absolute universal being and absolute nothingness, generation absolute and corruption absolute, origen of things generated that are within the sky, that are within the deepest depths of mines, and that are on the earth’s crust, amongst which last-named are plant and animal, the true conception “Man” and the truth of the soul’s conception of its own self; and still further such mentally-grasped forms as the conception of ideas mathematical, amongst which are number, pure geometry, stellar geometry, harmonical or musical geometry, optical geometry; and again, further still, such ideas as the conception of divine affairs, like the knowledge of the principles of the absolute self-existent in so far as he exists _per se_, and of the principles consequently adhering to him, such as potentiality, power and efficiency, first cause and accounting cause, essence and accidens, genus and species, incompatibility and homogeneity, agreement and disagreement, unity and multiplicity; and, still further, the fixing of the principles of the
