BARZELLOTTI, GIACOMO. – Philosopher, born in Florence in 1844, died in Rome in 1917. He taught in Pisa and Rome. A pupil of Maimani, partly a follower of Kant, though never original, his theoretical philosophy reduces to a psychological analysis of the fact of human knowledge. Moral values are posited as independent of science. The practical norm is inspired not by reason, but by the heart, by faith, by a very refined practical tact, not theoretical, guided by conscience.
He wrote: *La morale nella filosofia positiva* (Florence 1871); *D. Luzzaretti di Arcidosso detto il Santo* (Bologna 1885); *Santi, solitari e filosofi; saggi psicologici* (2nd ed., 1886); *Dal Rinascimento al Risorgimento* (Palermo 1909), in addition to articles scattered in various journals.
