The question of whether morality is objective or invented by humans is a central debate in philosophy, with compelling arguments on both sides but no definitive consensus. The following outlines major perspectives:

1. **Moral Realism (Objective Morality):**
   - Moral realism asserts that moral facts and values exist independently of human opinion. This means that certain actions are right or wrong regardless of what anyone thinks or feels about them.
   - Some proponents of moral realism, such as Immanuel Kant, argue that moral laws can be derived rationally and apply universally. For Kant, certain duties, like telling the truth or not causing harm, are mandated by rationality itself.
   - Divine command theorists argue that morality is grounded in the commands or nature of a transcendent deity, making moral truths objective and universal based on divine decree.

2. **Moral Subjectivism and Constructivism (Invented Morality):**
   - Contrary to moral realism, subjectivism and constructivism argue that moral values are not intrinsic to actions themselves but are constructed by individuals or societies.
   - Subjectivists hold that moral judgments are based on personal attitudes, feelings, or opinions. If morality is subjective, what is considered "right" or "wrong" may vary from person to person.
   - Social constructivists argue that moral values are constructed through social processes and shared within a cultural or community context. Thus, these values can change as social attitudes and cultures evolve.

3. **Moral Relativism:**
   - Moral relativism posits that what is right or wrong depends on the societal or cultural context. There are no absolute universal moral standards binding all people at all times, but rather each culture develops its own set of norms and practices.
   - This view accommodates the observed diversity of moral practices across different societies and historical periods, suggesting that morality adapts to human needs, conditions, and evolving understandings.

4. **Moral Nihilism:**
   - Moral nihilists go further than relativists or subjectivists by denying the existence of any moral facts whatsoever. According to nihilism, morality is merely an illusion, with no intrinsic truth-value, and moral statements do not refer to real properties or have any truth value.

Ultimately, the debate over whether morality is objective or invented is intertwined with broader philosophical inquiries into the nature of truth, facts, and human understanding. Each position has implications for ethical theory, the enforceability of moral norms, and the prospect of moral progress or reform. Philosophers and ethicists continue to explore and challenge these ideas, contributing to a dynamic and ongoing discussion on the true nature of morality.
