All human history attests That happiness for man, - the hungry sinner! - Since Eve ate apples, much depends on dinner. ~Lord Byron, Don Juan, Canto XIII, stanza 99
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.
Gluttony is a great fault; but we do not necessarily dislike a glutton. We only dislike the glutton when he becomes a gourmet-that is, we only dislike him when he not only wants the best for himself, but knows what is best for other people.
