On 25 September 2019, Steve Fuller gave a Codex Talk at the Royal Society of London, commemorating the ‘world’s top 50 innovators’ on the 500th anniversary of the death of Leonardo da Vinci. Da Vinci authored the ‘Codex’ in question, which is a notebook of his thoughts, including a drawing of ‘Vitruvian Man’, which begins Fuller’s talk.
The ‘fork in the road for the future of humanity’ refers to transhumanism and posthumanism, which Fuller treats as projecting radically alternative visions for the human condition.
