Moreover, see if in rendering a term named by the privation, he has failed to render the term of which it is the privation, eg the state, or contrary, or whatever it may be whose privation it is; also if he has omitted to add that in which the privation is naturally formed either without qualification or else that in which it is naturally formed primarily: eg whether in defining ignorance as a privation he has failed to say that it is the privation of knowledge; or has failed to add in what it is naturally formed, or, though he has added this, has failed to render the thing in which it is primarily formed, placing it (e.g.) in man or in the soul, and not in the reasoning faculty; for if in any of these respects he fails, he has made a mistake.
