André Pierre Le Guay de Prémontval (16 February 1716 – 2 September 1764) was a French mathematician and philosopher.
[1] In 1744, he was forced to flee France to Switzerland due to his criticism of Catholic doctrines,[2][3] accompanied by his student Marie Anne Victoire Pigeon; on 30 June 1746, they married.
[5] Later they moved to Berlin, where he was admitted to the Royal Prussian Academy of Sciences.
[6] Prémontval criticised the empiricist theory of the self, arguing that there is a real distinction between an individual's personality and soul that is often ignored, and that our possession of the later is our justification for our interest in the former.
[7] Prémontval’s hypothesis termed "psychocracy" proposed that there is real interaction between the body and soul, but it is an immaterial kind of influence as opposed to a physical kind.
