Raymond Ruyer (13 January 1902 – 1987) was a French philosopher in the late 20th century. His work covered topics including the philosophy of biology, the philosophy of informatics, the philosophy of value and others. His most popular book is The Gnosis of Princeton in which he presents his own philosophical views under the pretence that he was representing the views of an imaginary group of American scientists. He developed an account of panpsychism which was a major influence on philosophers such as Adolf Portmann, Gilbert Simondon, Gilles Deleuze and Félix Guattari.
