Moral monism is the view that there is only one correct moral theory that applies to all people in all situations. This theory is in contrast to moral pluralism, which holds that there are multiple correct moral theories that can apply to different people or situations.

John Stuart Mill is most closely associated with moral pluralism. In his book Utilitarianism, Mill argues that there is no one right way to live and that the best moral theory is the one that produces the greatest happiness for the greatest number of people.

Immanuel Kant is most closely associated with moral monism. In his book Groundwork of the Metaphysics of Morals, Kant argues that there is only one categorical imperative, which is to act only according to the maxim by which you can at the same time will that it should become a universal law.

There are a number of arguments against moral monism. One argument is that it is too simplistic and does not account for the complexity of moral decision-making. Another argument is that it is based on a false dichotomy between right and wrong. Finally, some argue that it is impossible to know for sure what the one correct moral theory is.

There are a number of arguments in favor of moral pluralism. One argument is that it is more realistic and better reflects the diversity of human values. Another argument is that it allows for more flexibility and adaptability in moral decision-making. Finally, some argue that it promotes tolerance and understanding of different moral perspectives.

There are a number of common objections to moral pluralism. One objection is that it can lead to moral relativism, where anything goes. Another objection is that it makes it difficult to resolve moral conflicts. Finally, some argue that it undermines the idea of objective moral truth.

Moral pluralism responds to the objection that it leads to moral relativism in a number of ways. One way is by arguing that there are still some moral values that are universally shared. Another way is by claiming that moral relativism is not necessarily a bad thing. Finally, moral pluralism points out that it does not mean that anything goes.

Moral monism responds to the objection that it is too simplistic and does not account for the complexity of moral decision-making in a number of ways. One way is by arguing that moral decision-making is not as complex as it seems. Another way is by claiming that there is a single moral principle that can be applied to all situations. Finally, moral monism points out that it does not mean that there is only one right answer to every moral question.

A moral dilemma is a situation in which a person is faced with a choice between two or more actions, each of which has morally significant consequences. Examples of moral dilemmas include choosing between saving your own life and saving the life of a stranger, deciding whether to tell the truth or lie to protect someone's feelings, and choosing between two equally good options.

Moral pluralists typically respond to moral dilemmas in a number of ways. One way is by arguing that there is no one right answer to a moral dilemma. Another way is by claiming that the best way to resolve a moral dilemma is to weigh the pros and cons of each option. Finally, moral pluralists point out that moral dilemmas are often a matter of personal opinion.

Moral monists typically respond to moral dilemmas in a number of ways. One way is by arguing that there is always one right answer to a moral dilemma. Another way is by claiming that the best way to resolve a moral dilemma is to apply the relevant moral principle. Finally, moral monists point out that moral dilemmas are often a matter of ignorance.

A moral principle is a general rule that guides moral decision-making. Examples of moral principles include the Golden Rule, the categorical imperative, and the utilitarian principle.

Moral principles help us to resolve moral dilemmas in a number of ways. They provide us with a framework for thinking about moral issues. They help us to identify the relevant factors to consider when making a moral decision. They allow us to weigh the pros and cons of different options.

A metaethical question is a question about the nature of morality itself. Examples of metaethical questions include: What is the nature of moral properties? What is the relationship between moral facts and other kinds of facts? What is the foundation of moral obligation?

Metaethics is different from normative ethics in a number of ways. Metaethics is concerned with the nature of morality, while normative ethics is concerned with what is right and wrong. Metaethics is more abstract and theoretical, while normative ethics is more practical and applied. Metaethics is concerned with the meaning of moral terms, while normative ethics is concerned with the justification of moral judgments.
