Write a short note on Moral Realism.

Moral realism is a metaethical stance that posits the existence of objective moral facts and values in the external world, independent of individual beliefs or cultural perspectives. Realists assert that ethical statements express propositions that can be objectively true or false, akin to statements in other domains of knowledge. The foundational idea is that moral properties exist in the world, and ethical claims aim to accurately describe these objective features. Moral realism contrasts with anti-realism, which denies the existence of objective moral truths and often views morality as subjective or culturally relative. While moral realism faces challenges such as the nature of moral properties and the epistemological basis for moral knowledge, proponents argue that it provides a robust foundation for understanding the objective and universal nature of ethical principles.
