Humanist Society Scotland is an organization that promotes humanism, a philosophy that emphasizes reason, ethics, and justice while rejecting supernatural beliefs. Founded in 1963, it advocates for a secular society where individuals can lead fulfilling lives based on human values and scientific understanding. The society offers support for those seeking non-religious ceremonies, such as weddings and naming ceremonies, and provides resources for education on humanist principles. It also engages in campaigns to promote human rights and social justice, aligning with broader movements like human rights advocacy and secularism.
