Giovanni Papini was an Italian journalist, essayist, novelist, short story writer, poet, literary critic, and philosopher. A controversial literary figure of the early and mid-twentieth century, he was the earliest and most enthusiastic representative and promoter of Italian pragmatism. Papini was admired for his writing style and engaged in heated polemics. Involved with avant-garde movements such as futurism and post-decadentism, he moved from one political and philosophical position to another, always dissatisfied and uneasy: he converted from anti-clericalism and atheism to Catholicism, and went from convinced interventionism – before 1915 – to an aversion to war. In the 1930s, after moving from individualism to conservatism, he finally became a fascist, while maintaining an aversion to Nazism.

Giovanni Carmelo Verga di Fontanabianca was an Italian realist (verista) writer, best known for his depictions of life in his native Sicily, especially the short story and later play Cavalleria rusticana and the novel I Malavoglia.

Giovanni Villani was an Italian banker, official, diplomat and chronicler from Florence who wrote the Nuova Cronica on the history of Florence. He was a leading statesman of Florence but later gained an unsavoury reputation and served time in prison as a result of the bankruptcy of a trading and banking company he worked for. His interest in and elaboration of economic details, statistical information, and political and psychological insight mark him as a more modern chronicler of late medieval Europe. His Cronica is viewed as the first introduction of statistics as a positive element in history. However, historian Kenneth R. Bartlett notes that, in contrast to his Renaissance-era successors, "his reliance on such elements as divine providence links Villani closely with the medieval vernacular chronicle tradition." In recurring themes made implicit through significant events described in his Cronica, Villani also emphasized three assumptions about the relationship of sin and morality to historical events, these being that excess brings disaster, that forces of right and wrong are in constant struggle, and that events are directly influenced by the will of God.

Girolamo Savonarola, OP or Jerome Savonarola was an ascetic Italian Dominican friar from Ferrara and a preacher active in Renaissance Florence. He became known for his prophecies of civic glory, his advocacy of the destruction of secular art and culture, and his calls for Christian renewal. He denounced clerical corruption, despotic rule, and the exploitation of the poor.

Giuseppe Maria Garibaldi was an Italian general, patriot, revolutionary and republican. He contributed to Italian unification and the creation of the Kingdom of Italy. He is considered one of the greatest generals of modern times and one of Italy's "fathers of the fatherland", along with Camillo Benso, Count of Cavour, Victor Emmanuel II of Italy and Giuseppe Mazzini. Garibaldi is also known as the "Hero of the Two Worlds" because of his military enterprises in South America and Europe.

His theory of knowledge is sometimes called scripturalism.
