Al-Ma’arri, also known under his Latin name Abulola Moarrensis (973 – 1057) was a blind Arab philosopher, poet, and writer. Despite holding a controversially irreligious worldview, he is regarded as one of the greatest classical Arabic poets. He was a robust naturalist and rationalist and attacked the dogmas and practices of many religions. He was a vegan, known in his time as moral vegetarianism, entreating: “do not desire as food the flesh of slaughtered animals / Or the white milk of mothers who intended its pure draught / for their young”.

Brigid was a novelist, critic, and campaigner for social reforms, including the rights of authors and animal rights. Her 1965 Sunday Times article is credited by psychologist Richard D. Ryder (another Sentientist) with having triggered the formation of the animal rights movement in England. Brigid was one of the signers of the Humanist Manifesto and was president of the National Anti-Vivisection Society.

Brigid wrote that she and her father were “natural, logical and happy atheists”. She said: “Reason can always disarm the irrational. If reason finds itself to be irrational, it can disarm it; and if one finds reason and discovers that eating animals is immoral, unnecessary, and done largely for superstitious reasons, then one is delivered from the compulsion to do it.”

Jeremy Bentham was an English philosopher, jurist, and social reformer regarded as the founder of modern utilitarianism. He was an atheist and an early advocate for granting moral consideration and rights to non-human animals based on their sentience, not on capacity to reason.

He wrote in 1780: “The day may come when the rest of the animal creation may acquire those rights which never could have been witholden from them but by the hand of tyranny… The question is not ‘Can they reason?’ nor, ‘Can they talk?’ but, ‘Can they suffer?’”

In our discussion he says: “Maybe there will come a point when Humanism ceases to be – that Humanism evolves into Sentientism. I would like to see that. And I would like to be part of the process that makes that happen.”
