[…] videbit quam primo statim dogmate p 3, seqq. in Hobbio hoc opinionis monstrum; nihil ex se & simpliciter malum Bonumve esse, tam feliciter prostraverit.[…] he shall see, forthwith and before all else, on p. 3 sqq. how fortunately he has, by means of doctrine, overthrown this monstrosity of an opinion in Hobbes, that nothing is simply and in itself bad or good.1674, Friedrich Gesen, Domini Samuelis Pufendorfii […] contra jus naturae iniquitas inque illius scrutinio infelicitas […], page 57:
Hobbio autem indecorum erat maximè hac in re, vel hoc in loco labi: cùm quia status civilis peculiare privilegium, cuilibet in statu naturali tribuere turpe fuit, etiam tum cùm statuum hujusmodi discrimina accuratissimè tradere præ se fert; […]But it was especially shameful for Hobbes to err in this matter, or in this place; for it is disgraceful for him to accord to anyone in the state of nature a peculiar privilege of civil society precisely where he pretends to discuss with the greatest accuracy the differences between these states […]1683, Richard Cumberland, De legibus naturae disquisitio philosophica […], page 54:
