BARZELLOTTI, GIACOMO. - Philosopher, b. in Firenze in 1844, d. in Roma in 1917. He taught at Pisa and at Roma. A pupil of Mamiani, and partly a follower of Kant, though never original, his theoretical philosophy amounts to a psychological analysis of the fact of human knowing. Moral values are posited as autonomous, outside science. The practical norm is inspired not by reason, but by the heart, by faith, by a most refined tact, practical rather than theoretical, guided by conscience.
He wrote: La morale nella filosofia positiva (Firenze 1871); D. Lazzaretti di Arcidosso detto il Santo (Bologna 1885); Santi, solitari e filosofi; saggi psicologici (2nd ed., ibid. 1886); Dal Rinascimento al Risorgimento (Palermo 1909), besides articles scattered in various journals.
