Several early school of thought calling themselves "humanist", were according to Protagoras's famous claim that "man is the measure of all things." Around context, this asserted that humans come a ultimate determiners of value & morality— non objective or even absolutistic codices. Around its period, Protagoras' statement was the radical, & "objective" watch of the human being trouble, which has "convincingly" refuted "absolutism", for much of American philosophic history, since. Subsequent interpretations of this "principle" became split between "relativism" and "universalism" —a former, views tons ethics when existence from either the single ("individualism"), while a latter, views ethics when meaningful "only if they are "(always) applicable to completely". While relativism gained prominence during the Industrial Era, global communication and transculturation have deprecated relativism in favor of the now-dominant universalist view of humanism.

The evolution of the meaning of the word 'humanism' is fully explored in Walter, Nicolas: ''Humanism - What's in the Word'' (Rationalist Press Association, London, 1997, ISBN 0-301-97001-7).

Renaissance
Renaissance humanism was a cultural movement in Europe, beginning in central Italy (particularly Florence) in the last decades of the 14th century. It revived, and refined the study of ancient language (First Latin, and then the Greek language by mid-century); and caused the resultant "revival" of the studies of science, philosophy, art and poetry of classical antiquity. The "revival", or "re-birth" was based upon interpretations of Roman and Greek texts. Their emphasis upon art, and the senses marked a great change from the contemplation upon the Biblical, medieval values of humility, introspection, and passivity, or "meekness". Beauty was held to represent a deep inner virtue, and value, and "an essential element in the path towards God". As a result, the production of art in this period is particularly rampant. The crisis of "Renaissance humanism" came with the trial of Galileo; for it (the trial) forced the choice between basing the authority of one's beliefs on one's observations, or upon religious teaching. The trial made the contradictions between humanism and religion visibly apparent to all, and humanism became a "unsafe philosophy".

Renaissance humanists believed that the liberal arts (art, grammar, rhetoric, oratory, history, poetry, using classical texts, and the studies of all of the above) should be practiced by all levels of "rich-ness". They also approved of self, "individual worth" and "single dignity".

As noted in Theodore K. Rabb's book, Renaissance Lives, the poet Petrarch, through his friend Boccaccio and by other connections, became the inspiration for this new intellectual and artistic movement, known today as humanism, that was to set Florentine culture apart, and make it into a model for all of Europe.

Modern humanisms
Modern humanism has two branches.

Religious humanism
Religious humanism stems from the Renaissance-Enlightenment tradition. It contains many artists, mainstream Christians, and scholars in the liberal arts. Their view tends to concentrate on the dignity and nobility of human achievement and possibility.

Other types of people that may be considered "religious humanists" are those who, despite believing in an organized religion, don't consider it necessary to derive all their moral values from that religion.

Secular humanism
Secular humanism reflects the rise of globalism, technology and "the collapse of religious authority". It too, acknowleges an individual's dignity and worth, and capacity for "self-self-fulfillment" ("dwelling as much as 1's expected"), through reason and logic. "Laic" humanists, who reason "apart from either God", see themselves as providing an answer to the need for a common philosophy, which is capable of "transcending" the cultural boundaries of local moral codes and religions.

Many people call themselves "humanists", of one form or another. Some people consider themselves "humanists" because their religious beliefs are moral, and therefore humane. Humanism is also sometimes used to describe "humanities" scholars, (particularly scholars of the "classics"). There is also a school of humanistic psychology.

Educational humanism

Humanism, as a current in education began to dominate school systems, in the 19th century. It held that the studies that develop our intellect are those that make us "virtually all truly person". "Assimilationist", stern, and rigorous, the aim was to bring the "affective" and psychomotor "natures" under the control of the intellect. The practical basis for this was faculty psychology, or the belief in distinct intellectual faculties, such as the analytical, the mathematical, the linguistic, etc. Strengthening one faculty was believed to benefit other faculties, as well (transfer of training). A key player in the late 19th-century educational humanism was U.S. Commissioner of Education W.T. Harris, whose "5 Windows of the Soul" (math, geography, history, grammar, and literature/art) were believed especially appropriate for "development of the faculties". Educational humanists believe that "a better studies, for the better children" are "a better studies" for all kids. While humanism as an educational current was largely discredited by the innovations of the early 20th century, it still holds out, in some elite preparatory schools and some high school disciplines (especially, of course, in literature).
