What are four different sources of moral law or truth?

Four different sources of moral law or truth include religious texts, which provide divine commandments and ethical guidelines; philosophical reasoning, which uses logic and ethics to derive moral principles; cultural norms, reflecting the values and practices of a society; and natural law, which posits that moral truths can be discerned from human nature and the world. Each source offers a unique perspective on what constitutes right and wrong, influencing individual and collective moral judgments.
