# Relativism — AP Euro Definition & Exam Guide

## Definition

In AP Euro, relativism is the late 19th-century philosophical position that values and knowledge are not absolute or objective but depend on perspective and context, a shift (KC-3.6.III) that eroded Enlightenment confidence in reason and helped produce modernism in thought and culture.

## What It Is

Relativism is the idea that there is no single, objective truth or universal set of values. What counts as "true" or "good" depends on who is looking and from where. In the [AP Euro](/ap-euro "fv-autolink") CED (KC-3.6.III), this "new relativism in values and the loss of confidence in the objectivity of knowledge" shows up in the later 19th century and leads directly to [modernism](/ap-euro/key-terms/modernism "fv-autolink") in intellectual and cultural life.

Here's the simple way to think about it. For most of the 1800s, Europeans believed science and [reason](/ap-euro/unit-5/romanticism/study-guide/f9m8GQjQ1Ei0CY0s7Y9C "fv-autolink") could nail down objective answers about nature and society (that's positivism). Then a wave of thinkers blew holes in that confidence. Nietzsche declared that morality was a human invention, not a cosmic fact. Freud argued your conscious, rational mind isn't even in charge of you. Physicists like Planck and Einstein showed that measurement itself depended on the observer. Stack those up and the old certainty collapses. Truth started to look like something filtered through perspective, instinct, and the unconscious rather than something fixed and waiting to be discovered.

## Why It Matters

Relativism sits in Topic 7.5 (Science and Intellectual Developments from 1815-1914) in [Unit 7](/ap-euro/unit-7 "fv-autolink"), supporting learning objective AP Euro 7.5.A, which asks you to explain how intellectual disciplines developed and changed across the period. The whole arc of 7.5 is a story of confidence and then doubt. The century opens with [positivism](/ap-euro/key-terms/positivism "fv-autolink") (KC-3.6.II.A), the belief that science alone provides real knowledge. It closes with relativism (KC-3.6.III), the loss of faith in objectivity. That pivot is exactly the kind of change-over-time argument AP Euro loves. Relativism is also the hinge connecting Unit 7 to the modernist art, literature, and postwar disillusionment you'll see carried into Unit 8, where World War I makes the doubt feel brutally confirmed.

## Connections

### [Positivism (Unit 7)](/ap-euro/key-terms/positivism)

Positivism is relativism's opposite and its setup. Positivists claimed science could deliver objective truth about everything, including human society. Relativism is what happens when that promise breaks down. Knowing both lets you frame the late 19th century as a swing from certainty to doubt.

### [Friedrich Nietzsche (Unit 7)](/ap-euro/key-terms/friedrich-nietzsche)

Nietzsche is the poster child for relativism on the exam. He argued that morality and truth were human creations, that rationality suppressed instinct and creativity, and that struggle drove [progress](/ap-euro/unit-8/20th-century-cultural-intellectual-artistic-developments/study-guide/Ma7uhdsmFnm7mWoX4HlT "fv-autolink") (KC-3.6.III.A). If an MCQ asks who embodied the relativity of truth and values, Nietzsche is usually the answer.

### [Freudian Psychology (Unit 7)](/ap-euro/key-terms/freudian-psychology)

Freud undermined objectivity from the inside. If unconscious drives shape what you think and perceive, then even your own reasoning isn't a neutral window on reality. That's the psychological version of relativism, and the CED pairs them in the same essential knowledge block.

### [Henri Bergson (Unit 7)](/ap-euro/key-terms/henri-bergson)

Bergson argued that intuition and lived experience reveal truths that cold rational analysis misses. He's part of the broader turn from reason to irrationality and impulse, which is the philosophical engine behind the new relativism.

## On the AP Exam

Relativism shows up most often in multiple-choice stems about late 19th-century intellectual change, usually paired with a quote or excerpt. Typical moves include identifying relativism as the movement that emphasized the relativity of truth and values, explaining how Nietzsche's attack on rationality fits the broader shift toward irrationality, and recognizing that Planck's quantum theory and Einstein's relativity reinforced philosophical relativism by introducing uncertainty and observer-dependence into physics itself. No released FRQ has used the word verbatim, but relativism is gold for LEQs and DBQs on intellectual continuity and change from roughly 1850 to 1920. The cleanest move is contrasting positivist confidence with relativist doubt and using relativism to explain the rise of modernism.

## relativism vs Einstein's theory of relativity

They sound alike but they're different categories of thing. Relativity is a physics theory about how space, time, and measurement depend on the observer's frame of reference. Relativism is a philosophical position about truth and values having no objective foundation. On the exam, Einstein's relativity is evidence that REINFORCED philosophical relativism (science itself seemed to abandon fixed certainty), but Einstein wasn't arguing that morality is subjective. Don't write that relativity 'proved' relativism; write that it eroded confidence in objective, Newtonian certainty.

## Key Takeaways

- Relativism is the late 19th-century belief that knowledge and values are not absolute or objective but depend on perspective and context (KC-3.6.III).
- It marks the collapse of positivist confidence that science alone could deliver objective truth, making the positivism-to-relativism arc the core change-over-time story of Topic 7.5.
- Nietzsche, Freud, and Bergson all fed relativism by emphasizing irrationality, instinct, and the unconscious over pure reason (KC-3.6.III.A).
- Planck's quantum theory and Einstein's relativity reinforced relativism by showing that even physics involved uncertainty and observer-dependence.
- The CED draws a straight line from relativism to modernism, so use relativism to explain why art, literature, and philosophy broke from traditional forms around 1900.
- Don't confuse philosophical relativism with Einstein's theory of relativity; one is a claim about values and truth, the other is a physics theory that happened to undermine certainty.

## FAQs

### What is relativism in AP Euro?

Relativism is the late 19th-century philosophical position that truth and values are not objective or universal but depend on [perspective](/ap-euro/key-terms/perspective "fv-autolink") and context. The CED (KC-3.6.III) credits this new relativism with producing modernism in intellectual and cultural life.

### Is relativism the same thing as Einstein's theory of relativity?

No. Relativity is a physics theory about space, time, and frames of reference, while relativism is a philosophical claim that truth and values have no objective foundation. On the exam, Einstein's relativity and Planck's quantum theory are evidence that reinforced relativism by undermining Newtonian certainty, but they aren't the same idea.

### How is relativism different from positivism?

Positivism (KC-3.6.II.A) held that science alone provides real, [objective knowledge](/ap-euro/key-terms/objective-knowledge "fv-autolink") about nature and society. Relativism is its reversal, the loss of confidence that any knowledge is fully objective. Think of them as the bookends of 19th-century thought, with positivism dominating early-to-mid century and relativism emerging in the later decades.

### Which thinkers are associated with relativism on the AP Euro exam?

Friedrich Nietzsche is the big one, arguing morality was a human invention and that rationality suppressed instinct. Freud (the unconscious mind), Henri Bergson (intuition over analysis), and physicists Planck and Einstein (uncertainty and observer-dependence) all fed the same loss of confidence in objective knowledge.

### Did relativism cause modernism?

Yes, that's exactly how the CED frames it. KC-3.6.III states that the new relativism in values and the loss of confidence in objective knowledge led to modernism in intellectual and cultural life, so on essays you can use relativism as the cause behind modernist breaks with tradition in art, literature, and philosophy.
