Forms

potentiālitās f (genitive potentiālitātis); third declension[1][2]

Etymology

It is formed from Latin potentiālis (“potential”) + -tās.[3][1] Köbler refers it further to potēns (“powerful, able”).[1]

Earliest recorded meaning

Köbler records it in the Summa theologiae of Thomas Aquinas, dated 1265–1273.[1] There Thomas says that God is pure act and has nothing of potentiality (Deus est purus actus, non habens aliquid de potentialitate).[4]

Semantic evolution

It is a word of scholastic philosophy.[4][3] In Thomas Aquinas it is a synonym of possibilitās, potentia and potestās, and the opposite both of actus and of impossibilitas, impotentia and impotentialitas.[4] British writers used it in logic, as when a Pseudo-Grosseteste treatise speaks of the potentiality of prime matter,[3] and a 13th-century philosophical text from Poland says that simple substances have some potentiality mixed in.[2] English potentiality (1620s) is formed from potential or else taken from the Medieval Latin word.[5]

Timeline

  • 1265–1273 – Thomas Aquinas uses it in the Summa theologiae.[1][4]
  • 13th century – A philosophical text from Poland says that simple substances are not pure act.[2]
  • 1620s – English potentiality appears, perhaps from the Medieval Latin word.[5]
