Yet another ancient political debate concerns whether public policy needs to be based on certain norms, or ethical principles.
and a few modern political philosophers — e.g., Socrates, Plato,
Aristotle, Aquinas, Spinoza, John Locke, et al. — argued that to learn
how to govern, one must have certain values for which governing needs to
aim. These would be justice, peace, equality, or liberty. The source of
these values might be one or another conception of the divine, human
nature, intuition, majority sentiment or something like these.
