I mostly identify as a Freethinker. That seems the most positive way of expressing my non-theistic, non-supernaturalist views. Yes, I am an atheist since I do not believe in any divine beings, but I choose not to be defined by a negative word. This is one reason I also call myself a Humanist and have a secular “ordination” as a Humanist Celebrant through the American Humanist Society.
You’ll notice in the following descriptive definitions of Humanism, it is not a belief-system. I do not “believe” in Humanism. It’s a “philosophy of life” based on reason and ethical living.
“Humanism is a progressive philosophy of life that, without theism or other supernatural beliefs, affirms our ability and responsibility to lead ethical lives of personal fulfillment that aspire to the greater good.”
– American Humanist Association
“Humanism is a rational philosophy informed by science, inspired by art, and motivated by compassion. Affirming the dignity of each human being, it supports the maximization of individual liberty and opportunity consonant with social and planetary responsibility. It advocates the extension of participatory democracy and the expansion of the open society, standing for human rights and social justice. Free of supernaturalism, it recognizes human beings as a part of nature and holds that values-be they religious, ethical, social, or political-have their source in human experience and culture. Humanism thus derives the goals of life from human need and interest rather than from theological or ideological abstractions, and asserts that humanity must take responsibility for its own destiny.”
