Inquisitio consilii est finita in actu ex duplici parte, scilicet ex parte principii, et ex parte termini, quia accipitur in inquisitione consilii duplex principium: sicut enim finis habet rationem principii, ita id quod agitur propter finem, habet rationem conclusionis.
Counsel's investigation is actually finite on both sides, on that of its principle, and on that of its term, because a twofold principle is available in counsel's investigation: just as the end holds the formal aspect of a principle, so the means hold the formal aspect of a conclusion.
Unde id quod primo agendum occurrit, habet rationem ultimae conclusionis, ad quam inquisitio terminatur.
Wherefore that which presents itself as to be done first, holds the formal aspect of an ultimate conclusion whereat the investigation comes to an end.
Nihil autem prohibet consilium potentia infinitum esse, secundum quod in infinitum possunt aliqua occurrere consilio inquirenda.
Nothing however prevents counsel from being infinite potentially, for as much as an infinite number of things may present themselves to be inquired into by means of counsel.
Singularia non sunt infinita actu, sed in potentia tantum.
Singulars are infinite; not actually, but only potentially.
