Humanism
Humanism is a philosophical and ethical stance that emphasizes the value and agency of human beings, individually and collectively, and generally prefers critical thinking and evidence (rationalism and empiricism) over acceptance of dogma or superstition. The meaning of the term "humanism" has fluctuated according to the successive intellectual movements which have identified with it. The term was coined by theologian Friedrich Niethammer at the beginning of the 19th century to refer to a system of education based on the study of classical literature ("classical humanism"). Generally, however, humanism refers to a perspective that affirms some notion of human freedom and progress. It views humans as solely responsible for the promotion and development of individuals and emphasizes a concern for man in relation to the world.
Renaissance architecture
Leon Battista Alberti, born in Genoa (1402–1472), was an important Humanist theoretician and designer whose book on architecture "De re Aedificatoria" was to have lasting effect. An aspect of Humanism was an emphasis of the anatomy of nature, in particular the human form, a science first studied by the Ancient Greeks. Humanism made man the measure of things. Alberti perceived the architect as a person with great social responsibilities.
He designed a number of buildings, but unlike Brunelleschi, he did not see himself as a builder in a practical sense and so left the supervision of the work to others. Miraculously, one of his greatest designs, that of the Church of Sant'Andrea in Mantua, was brought to completion with its character essentially intact. Not so the church of San Francesco in Rimini, a rebuilding of a Gothic structure, which, like Sant'Andrea, was to have a façade reminiscent of a Roman triumphal arch. This was left sadly incomplete.
