Humanism is a philosophical and ethical stance that emphasizes the value and agency of human beings, individually and collectively, and affirms their ability to improve their lives using reason, ingenuity, science, ethics, and social, ecological and economic justice in decision-making.

The Humanist Society of South Australia advocates for a just and compassionate society, that treats all people as deserving of the same respect, dignity and opportunity to live up to their full potential as members of society. All policy should have regard to the Universal Declaration of Human Rights while also having consideration for future sustainability, cultural, social and ecological considerations.
