Concept description
The ladder of abstraction is a concept created by American linguist S. I. Hayakawa in his 1939 book Language in Action to describe the way that humans think and communicate in varying degrees of abstraction.
Hayakawa described a progression of concepts applicable to a single cow named Bessie:
- wealth (most abstract, top of the ladder)
- assets
- farm assets
- livestock
- cows
- the cow named Bessie
In varying contexts, any of these concepts may be appropriate. Farm children most likely think in highly concrete terms, referring to the cow with the bell on her neck as Bessie. At feeding time, the farmer probably thinks in terms of cows and livestock. When selling the farm, Bessie and the other cows are thought of in terms of farm assets which ultimately equate to wealth.
