Humanism is a broad category of ethical philosophies that affirm the dignity and worth of all people, based on the ability to determine right and wrong by appealing to universal human qualities, particularly rationality, without resorting to the supernatural or alleged divine authority from religious texts. It is a component of a variety of more specific philosophical systems. Humanism can be considered as a process by which truth and morality is sought through human investigation; as such, views on morals can change when new knowledge and information is discovered. In focusing on the capacity for self-determination, humanism rejects transcendental justifications, such as a dependence on faith, the supernatural, or texts of allegedly divine origin. Humanists endorse universal morality based on the commonality of the human condition, suggesting that solutions to human social and cultural problems cannot be parochial.
