Lactantius

“ For if we must look to the heaven, it is undoubtedly for no other reason than on account of religion; if religion is taken away, we have nothing to do with the heaven. Therefore we must either look in that direction or bend down to the earth. We are not able to bend down to the earth, even if we should wish, since our posture is upright. ”

“ Again, those creatures which look forward to the future and lay up for themselves food, plainly have foresight. Indications of reason are also found in many of them. For since they desire things useful to themselves, guard against evils, avoid dangers, prepare for themselves lurking-places standing open in different places with various outlets, assuredly they have some understanding. Can any one deny that they are possessed of reason, since they often deceive man himself? ”

“ Therefore the chief good of man is in religion only; for the other things, even those which are supposed to be peculiar to man, are found in the other animals also. For when they discern and distinguish their own voices [1] by peculiar marks among themselves, they seem to converse: they also appear to have a kind of smile, when with soothed ears, and contracted mouth, and with eyes relaxed to sportiveness, they fawn upon man, or upon their own mates and young. ”

“ And concerning this the opinion of Cicero is true: “Of so many kinds of animals,” he says, “there is none except man which has any knowledge of God; and among men themselves, there is no nation either so uncivilized or so savage, which, even if it is ignorant of due conceptions of the Deity, does not know that some conception of Him ought to be entertained.” ”
