Humanism is a philosophical and ethical stance that emphasizes the value and agency of human beings, individually and collectively, and affirms their ability to improve their lives through the use of reason and ingenuity as opposed to submitting blindly to tradition and authority or sinking into cruelty and brutality. The term was coined in 1808 by the early nineteenth century German educational reformer and theologian Friedrich Niethammer and gradually adopted into English. Niethammer had wished to introduce into German education the humane values of ancient Greece and Rome. Niethhammer was a Lutheran theologian. Since the twentieth century, however, Anglophone humanist movements have usually been aligned with secularism, and today humanism typically refers to a non-theistic life stance centred on human agency and looking to science rather than revelation from a supernatural source to understand the world.
The word "Humanism" is ultimately derived from the Latin concept humanitas, and, like most other words ending in -ism, entered English in the nineteenth century. However, historians agree that the concept predates the label invented to describe it, encompassing the various meanings ascribed to humanitas, which included both benevolence toward one's fellow humans and the values imparted by bonae litterae or humane learning (literally "good letters").
In the second century AD, a Latin grammarian, Aulus Gellius (c. 125 – c. 180), complained:
Those who have spoken Latin and have used the language correctly do not give to the word humanitas the meaning which it is commonly thought to have, namely, what the Greeks call φιλανθρωπία (philanthropy), signifying a kind of friendly spirit and good-feeling towards all men without distinction; but they gave to humanitas the force of the Greek παιδεία (paideia); that is, what we call eruditionem institutionemque in bonas artes, or "education and training in the liberal arts". Those who earnestly desire and seek after these are most highly humanized. For the desire to pursue of that kind of knowledge, and the training given by it, has been granted to humanity alone of all the animals, and for that reason it is termed humanitas, or "humanity".
