Yves is a philosopher, essayist and editor. He is a libertarian, an egalitarian and an antispeciesist activist. He is one of the founding members of the French-language journal Cahiers antispécistes (“Antispeciesist Notebooks”) and of the events Veggie Pride, Les Estivales de la question animale (“The Summers of the Animal Question”) and the march to close all slaughterhouses.
Yves is an atheist who is critical of humanism, describing it as a form of elitism. He is a hedonistic utilitarian, who advocates placing sentient individuals at the center of moral concern because they have desires, perceptions, emotions and a will of their own. Yves was influenced by Peter Singer‘s Animal Liberation and is a supporter of Singer’s conception of speciesism, seeing it as instrumental in deconstructing anthropocentric morality.

Henry was a writer and campaigner for social reform in the fields of prisons, schools, economic institutions, and the treatment of non-human animals. He was a noted ethical vegetarian/vegan, anti-vivisectionist, socialist, and pacifist, and was well known as a literary critic, biographer, classical scholar and naturalist.  Salt is considered, by some, to be the “father of animal rights,” having been an early writer to argue explicitly in favour of the topic, in his “Animals’ Rights: Considered in Relation to Social Progress” (1892).

He wrote: “[The] notion of the life of an animal having ‘no moral purpose,’ belongs to a class of ideas which cannot possibly be accepted by the advanced humanitarian thought of the present day—it is a purely arbitrary assumption, at variance with our best instincts, at variance with our best science, and absolutely fatal (if the subject be clearly thought out) to any full realization of animals’ rights.”

Henry also wrote extensively on his rationalism and naturalism, saying: “Religion has never befriended the cause of humaneness. Its monstrous doctrine of eternal punishment and the torture of the damned underlies much of the barbarity with which man has treated man; and the deep division imagined by the Church between the human being, with his immortal soul, and the soulless “beasts”, has been responsible for an incalculable sum of cruelty.”

Strato (~335 – ~269 BCE) was a Peripatetic philosopher, and the third director of the Lyceum after the death of Theophrastus. He devoted himself especially to the study of natural science, and increased the naturalistic elements in Aristotle’s thought to such an extent that he denied the need for an active god to construct the universe preferring to place the government of the universe in the unconscious force of nature alone. He wrote three books relating to animals but his stance on the moral salience of sentience is unclear. He may well have been vegetarian/vegan given the philosophy of Theophrastus, his predecessor, and others in the Peripatetic and Pythagorean traditions.
Strato of Lampsacus on Wikipedia

Theophrastus (~371 – ~287 BCE) , a Greek native of Eresos in Lesbos, was the successor to Aristotle in the Peripatetic school. He was vegetarian or vegan, on the grounds that farming animals robs them of life and was therefore unjust. Non-human animals, he said, can reason, sense, and feel just as human beings do.  He seems to have had a naturalistic worldview. He doubted the idea of a spirit independent of organic activity, although stopped short of completely rejecting it.

Woody is an actor and playwright. He is the recipient of numerous accolades, including a Primetime Emmy Award, and has been nominated for three Academy Awards and four Golden Globe Awards.

He has said: “I was getting into theology and studying the roots of the Bible, but then I started to discover the man-made nature of it. I started seeing things that made me ask ‘Is God really speaking through this instrument?’ My eyes opened to the reality of the bible being just a document to control people.” He is vegan.
