Eugenio Vittorio Rignano (31 May 1870 in Livorno – 9 February 1930 in Milan) was a Jewish Italian philosopher.
[8] His book The Nature of Life (1930) was described in a review as presenting a "militant, at times almost an evangelical exposition and defense of an energetic vitalism.
"[9] However, historian Peter J. Bowler has written that Rignano rejected both materialism and vitalism and adopted a similar position to what was known as emergent evolution.
[10] Li Dazhao, one of the founders of the China Communist Party, was an avid reader of Rignano's works.
[11] Rignano's views on acquired characteristics and organic memory are discussed in detail by historian Laura Otis and psychologist Daniel Schacter.
