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.
Transhumanism
Fundamental ideas of transhumanism were first advanced in 1923 by the British geneticist J. B. S. Haldane in his essay "Daedalus: Science and the Future", which predicted that great benefits would come from the application of advanced sciences to human biology—and that every such advance would first appear to someone as blasphemy or perversion, "indecent and unnatural". In particular, he was interested in the development of the science of eugenics, ectogenesis (creating and sustaining life in an artificial environment), and the application of genetics to improve human characteristics, such as health and intelligence.
