Introduction to Relativism (with rough definitions as a first pass)

Relativism comes in miscellaneous forms, but all stripes of relativism agree on at least two features. Firstly, relativism asserts that at least certain properties (like beauty or moral goodness), or classes of things (like knowledge or truth) are not absolute but depend on specific assessment frameworks (such as cultural norms or personal criteria), and the truth of related claims is contingent on identifying the appropriate framework. And secondly, relativists all deny that any framework is uniquely privileged over all others.

(Cf., Baghramian & Carter, 2020; Westacott n.d. -b)

It is also imperative here to underscore the distinction between relativism and expressivism. As contended by Carter (n.d.), relativists adhere to a cognitivist stance, wherein their evaluative judgments principally manifest as expressions of belief rather than some non-cognitive mental states. Relativists do make truth-apt propositions, it is just that their truth or falsity is relative.

The Inception of Relativism (the historical motivation for relativism)

1. Ancient Origins

According to Baghramian (2020) and Westacott (n.d.-a), the concept of relativism, though a contemporary term, finds roots in ancient Western philosophy, notably championed by Protagoras of Abdera around 490–420 BC. Protagoras’s dictum, “Man is the measure of all things,” (Plato, Theaetetus 152a 2–4, as cited in Baghramian & Carter, 2020) serves as an early expression of relativism, suggesting that perception shapes reality. However, the extent of Protagoras’ relativism remains debated, with interpretations ranging from radical subjectivism to a broader ethical dimension. Plato’s rebuttal to Protagoras adds a social and ethical layer to Protagorean relativism, implying that societal or legal norms dictate non-relative truth. His other objection to Protagorean relativism is that it is self-refuting, as it must acknowledge its own falsity if it accepts that those who believe relativism is false are correct.

“…whatever view a city takes on these matters and establishes as its law or convention, is truth and fact for that city.”

Plato, Theaetetus 172a

2. David Hume

Despite its ancient origins, relativism’s implications continue to spark scholarly discussion, reflecting its enduring relevance in philosophical discourse. For example, David Hume (2007a) is famous for his ethical anti-rationalism, which states that moralities are based on sentiment, which is subjective (or relative), rather than on reason, which is rather objective (or non-relative).
