Word of the Month: Equipoise

David Zapatka

While attending the Theosophical Society Convention in Wheaton, Ill., this summer, I saw one of the presenters use the word “equipoise” in his presentation. The usage of the word described a relationship balance between two philosophical thoughts.

Equipoise—equi·poise noun 1. A state of equilibrium 2. Counterbalance 3. Balance of forces or interests verb 1. (transitive) to act or to make act as an equipoise 2. (transitive) to cause to be or stay in equipoise.

Origin and Etymologyfrom equi– “equal” + the noun poise, replacing the phrase equal poise. The earliest evidence for equipoise is from 1647, in the writing of Nathaniel Ward, clergyman and compiler of a law code for Massachusetts. More early evidence of equipoise is from 1658 in the writing of J. Robinson. Equipoise is formed within English, by compounding “equal” and “poise.”
