Abstract
This chapter considers the status and coherence of modern humanism as a secular and ethical philosophy. As secular, humanism prioritizes the naturalistic worldview, and privileges information from the social and cognitive sciences about human sociality and morality. As ethical, humanism does more than recommend specific moral virtues and rules, by proposing methods to evaluate moralities and recommend ideals of moral progress for all peoples around the world. Moral relativism is one of most talked‐about yet least understood notions around today. Despite what one might hear, morality is neither a matter of taste nor preference, it is not arbitrary or immune from criticism, and we don't have to tolerate just anybody's moral opinions. Morality can be objectively studied, morality can be rationally debated and evaluated, there are justifiable ways to determine better and worse moral norms, and important moral norms can be reasonably recommended for all people.
