"By all which it is most manifest, that it is not for nourishment, or want, or any necessity, but for mere gluttony, wantonness, and expensiveness, that they make a pleasure of villany."
"As, therefore, among men, he who, for the sake of his own safety, or that of his children or country, either seizes the wealth of certain persons, or oppresses some region of city, has necessity for the pretext of his injustice; but he who acts in this manner through the acquisition of wealth, or through satiety or luxurious pleasure, and for the purpose of satisfying desires which are not necessary, appears to be inhospitable, intemperate, and depraved."
"Sextius believed that man had enough sustenance without resorting to blood, and that a habit of cruelty is formed whenever butchery is practised for pleasure."
"A man can live and be healthy without killing animals for food; therefore, if he eats meat, he participates in taking animal life merely for the sake of his appetite. And to act so is immoral."
"I hold that the depravity of the physical and moral nature of man originated in his unnatural habits of life. The origin of man, like that of the universe of which he is a part, is enveloped in impenetrable mystery. His generations either had a beginning, or they had not. The weight of evidence in favour of each of these suppositions seems tolerably equal; and it is perfectly unimportant to the present argument which is assumed. The language spoken however by the mythology of nearly all religions seems to prove, that at some distant period man forsook the path of nature, and sacrificed the purity and happiness of his being to unnatural appetites. The date of this event, seems to have also been that of some great change in the climates of the earth, with which it has an obvious correspondence. The allegory of Adam and Eve eating of the tree of evil, and entailing upon their posterity the wrath of God, and the loss of everlasting life, admits of no other explanation, than the disease and crime that have flowed from unnatural diet."
I know I read something closer to the sentence in this post, but I can't find it right now. It's going to bug me
