Nam qui hominem, quamuis ob merita damnatum, in conspectu suo iugulari pro uoluptate computat, conscientiam suam polluit, tam scilicet, quam si homic… - Lactantius

Solus (homo) sapientia instructus est ut religionem solus intellegat, et haec est hominis atque mutorum vel praecipua, vel sola distantia; nam caetera quae videntur hominis esse propria, etsi non sint talia in mutis, tamen similia videri possunt … Quid tam proprium homini quam ratio, et providentia futuri? Atqui sunt animalia, quae latibulis suis diversos, et plures exitus pandant; ut si quod periculum inciderit, fuga pateat obsessis; quod non facerent, nisi inesset illis intelligentia, et cogitatio. Alia provident in futurum.

Man only is endowed with wisdom so as to understand religion, and this is the principal if not the only difference betwixt him and dumb animals; for other things that seem peculiar to him, though they are not the same in them, yet they appear to be alike … What is there more peculiar to man than reason, and foresight? Yet there are animals which make several different ways of retiring from their dens; that when in danger they may escape; which without understanding and forethought they could not do. Others make provision for the future.

For he who reckons it a pleasure that a man, though justly condemned, should be slain in his sight, pollutes his conscience as much as if he should become a spectator and a sharer of a homicide which is secretly committed.
