Humanism

Humanism is a broad category of ethical philosophies that affirm de dignity and worth of all people, based on the ability to determine right and wrong by appealing to universal human qualities, particularly rationality.

Erasmus

Renaissance humanism was a movement that affected the cultural, political, social and literary landscape of Europe starting in the last decades of the 14th century. It revived the study of Latin and Greek with the resultant revival of the studies of science, philosophy, art and poetry of classical antiquity. Noteworthy humanists from this period include the Dutch theologian Erasmus, the English author Thomas More, the French writer Francois Rabelais and the Italian poet Francesco Petrarch.

Petrus Mosellanus belonged to the category of christian humanist of that period.
