Meta-ethics
the branch of ethics that examines what moral language is about and how it can be justified
it considers second-order questions about the nature and purpose of morality e.g. what is the meaning of ‘good’, ‘bad’, ‘right’ or ‘wrong’?
Second-order questions
meta-ethical questions about the nature and purpose of morality
Ethical naturalism
the meta-ethical view that morality is defined by facts about nature or human nature
Ethical non-naturalism
the meta-ethical view that moral knowledge is a factual property known by intuition or by God’s commands
Cognitivism
the view that significant language is truth-apt (capable of being true or false). Meaning is a matter of empirical fact or relation of ideas
Non-cognitivism
the view that some meaningful language is not truth-apt (not capable of being true or false). Meaning is sometimes a matter of empirical fact or relation of ideas but may also be more connected to use.
Divine Command Theory (in a nutshell)
Christian Divine Command Theory
in Protestant Christianity:
- God is the Creator of everything
- humans are created in God’s image
- therefore, human moral behaviour should literally follow God’s commands
- for those who live by Sola Scriptura, God’s commands are seen in scripture
- DCT is based on both God’s moral character and God’s moral commands e.g. Ten Commandments, Sermon on the Mount
DCT - John Calvin (Protestantism)
DCT - Karl Barth (Protestantism)

Mill’s Utilitarianism
Strengths of ethical naturalism
Naturalistic fallacy
G.E. Moore’s argument that it is a fallacy when people reason from facts to moral claims i.e. defining good in terms of natural properties like pleasure, survival and happiness

Intuitionism
a form of non-naturalism
the meta-ethical view that moral knowledge is a factual property known by intuition
- intuitions are not supported by inference from other beliefs, so moral judgements are self-evident to those who hold them
- a form of moral realism: moral truths exist independently of persons
Intuitionism - W.D. Ross
there are prima facie duties we must instinctively do
provided there is mental maturity, if there are conflicting duties, intuition will tell one what to do
