Moreover, in a system of two bodies mutually acting upon each other, since the differences between their centres and the common centre of gravity of both are reciprocally as the bodies, the relative motions of those bodies, whether of approaching to or of receding from that centre, will be equal junong themselves. Therefore since the changes which happen to motions are equal and directed to contrary parts.

Actioni contrarium semper et aequalem esse reactionem: sive corporum duorum actiones in se mutuo semper esse aequales et in partes contrarias dirigi.

Another quote from the 1680s

Ignorance of the law excuses no man; not that all men know the law, but because 'tis an excuse every man will plead, and no man can tell how to confute him.

Another quote from Age of Enlightenment

Of all the animals, with which this globe is peopled, there is none towards whom nature seems, at first sight, to have exercis'd more cruelty than towards man, in the numberless wants and necessities, with which she has loaded him, and in the slender means, which she affords to the relieving these necessities.

These eyes of mine would look on only thee
In that last hour when light shall fail.
Embrace me, dear, in death! Let thy hand be
In my cold fingers pale!
