Based on, concerned with, or verifiable by observation or experience rather than theory or pure logic.

Implies hands-on observation, laboratory testing, or gathered sensory data rather than abstract deduction.

The story behind the word. In ancient Greece, 'empirics' were medical practitioners who based their remedies on practical trial-and-error experience rather than dogmatic theoretical systems. While high-minded theorists initially used the word almost disparagingly, the Enlightenment elevated empirical method to the gold standard of modern science.

Word relationships

  • observational: Focuses on watching without intervention, whereas empirical can include experimental manipulation.
  • experimental: Specifically highlights active experimentation rather than passive observation.
  • theoretical: Relies on abstract principles rather than observed data.
  • speculative: Based on conjecture rather than solid sensory evidence.

Commonly confused with

  • a priori: Empirical knowledge comes after experience (a posteriori), whereas a priori knowledge exists prior to experience.

Word family

  • empiricism (noun): The philosophical doctrine that knowledge derives from sensory experience.
  • empiricist (noun): A person who supports empirical principles.

Memory hook

Think of an EMPIRe built on physical concrete and bricks you can touch, not imaginary plans. Touch it, measure it, test it—that is empirical.

When not to use

Do not use to describe purely theoretical mathematics or logical proofs that rely entirely on definition.

Fun facts

  • Ancient 'Empiric' doctors were often contrasted with 'Dogmatists' who treated patients strictly by philosophical principles.
