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.
Susan Sackett
Although raised as a reform Jew, Susan Sackett considers herself a secular humanist and has been active in Humanism since 1989. 
She was first introduced to secular humanism by Gene Roddenberry after finding on his desk a copy of Isaac Asimov's book Asimov's Guide to the Bible. "I discovered that I was in line with this way of thinking without knowing there was a name for it". The two began attending conventions together and met prominent skeptics such as James Randi.
From 2000 to 2010 she was president of Humanist Society of Greater Phoenix. She is on the Board of Directors of the American Humanist Association, a member of Mensa, the Academy of Television Arts & Sciences (ATAS), and Writers Guild of America (WGA).
