secular humanism
a broad perspective, increasingly influential in Western countries since the mid-20th century, that can be characterized by some or all of the following: (a) a belief in seeking solutions to human problems through science and rational thought rather than through religion or traditional forms of morality; (b) a focus on this world rather than on a putative afterlife; (c) an emphasis on an intrinsic human potential for growth rather than on human limitation or sinfulness; (d) a search for new truth and a belief in free thought, free speech, and free inquiry as the means to find it; (e) an acceptance of cultural and human diversity, including sexual diversity; and (f) an acceptance of some degree of relativism in ethics, usually accompanied by some type of utilitarianism in practice.
