Richard Weikart, professor of history at California State University, joins Justin to talk about his new book ‘The Death of Humanity’. He says the loss of belief in the value of human life is leading to disastrous consequences for society.

Peter Singer is an Australian ethicist who believes we should dispense with the concept of the sanctity of human life in favour of a view of ‘personhood’. Humans who are less capable of having preferences, such as babies, have less claim to be kept alive.

They debate whether this view of humanity is dangerous and Susan Blackmore, atheist psychologist and philosopher also joins the conversation.
