Etymology of aesthetic

Asesthetic

The term aesthetics comes from the Greek αισθητική (aisthetike) meaning "sensation" from αίσθησιν (aisthesin) or "sense". It was appropriated by Alexander Gottlieb Baumgarten in 1735 to mean "the science of how things are known via the senses." The term aesthetics was used in German, shortly after Baumgarten introduced its Latin form (Aesthetica), but was not widely used in English until the beginning of the 19th century. However, much the same study was called studying the "standards of taste" or "judgments of taste" in English, following the vocabulary set by David Hume prior to the introduction of the term "aesthetics."
