Alberto Radicati, Count of Passerano (Torino, 11 November 1698 – 24 October 1737, The Hague), was an 18th-century historian, philosopher and free-thinker. He was the reputed author of the 1732 work A Philosophical Dissertation upon Death, Composed for the Consolation of the Unhappy by a Friend of Truth, published in London. This work created a scandal and led to the arrest of Radicati and his translator. The Dissertation upon Death is referenced by George Berkeley in his 1733 , section 5. There Radicati's work is used as an example of a free-thinker explicitly adopting the radical views attributed to the free-thinkers by Berkeley in his 1732 dialogue Alciphron, and so to defend Berkeley against the charge of attacking a strawman.
