The author shows very well how the history of vegetarianism is old and rich. He leans on First of lAntiquité; and we realize that each other flow in Figure arguments very similar to those heard today lon. The second part is more daring but convincing: Leglise would have condemned vegetarians because they would be kinder than God towards non-humans. The thesis is strong, could probably be qualified (because many Christians beginning with Francis Assisi protected the animals) but is still documented and seductive. The last two parts are more focused on today. One of the themes that do not appeal to Luc Ferry and other Francis Wolf of this world (followers of bullfighting and great humanists before the LORD), this is as lethic animal sorigine in the Enlightenment. For Rousseau and all other human rights defenders were beasts. The last part, sometimes lyrical, is on the contemporary period which is in phase végétarianisation so to speak. The part about Gandhi is fascinating. All this is very well written; we do not sennuie.
