Latin

Conatus quo unaquæque res in suo esse perseverare conatur, nihil est præter ipsius rei actualem essentiam.

English (Elwes 1883)

The endeavour, wherewith everything endeavours to persist in its own being, is nothing else but the actual essence of the thing in question.

Modern English

The *conatus* by which each thing strives to persist in its being is nothing other than the actual essence of that thing.
