Latin Grammar: Subject Infinitive
Deinde dedit causam propter quam magis adiuvat Naturalem scientiam quam aliam, dicendo: EST ENIM QUASI PRINCIPIUM ANIMALIUM. Idest, et causa in hoc est quia cognoscere de animalibus est maxima cognitio partium naturalium, et anima est principium animalium. Unde necessarium est ut scire de anima sit necessarium in cognitione animalium, non tantum utile.
As you know, the infinitive, or second principal part of a verb, is a verbal noun. It can, therefore, be used as the subject or object of a verb. As a subject, it is often--although not always--rendered in English with an -ing ending. For example: Videre est credere = Seeing is believing.
