A. a focus on humankind as the core of beliefs and ideas
Explanation:
Humanism is a polysemic concept that applies both to the study of human letters, classical studies and Greco-Roman philology, as well as to a generic doctrine or vital attitude that conceives human values in an integrated way. On the other hand, humanism is also called "Belief system centered on the principle that the needs of sensitivity and human intelligence can be met without having to accept the existence of God and the preaching of religions," which approximates secularism or secularist positions. It is applied as a denomination to different philosophical currents, although in particular, to Renaissance humanism (the European cultural current developed parallel to the Renaissance from its origins in 15th-century Italy), characterized at the same time by its classical philological vocation and for his anthropocentrism against medieval theocentrism.
