0055: Ens, Esse, and Actus Essendi

Entry 0055: Ens, Esse, and Actus Essendi

On 24 January 2009, the Blog “Reality: Reflections on Being and Existence” by Daniel D. De Haan reported this interesting remark on the meaning of esse.

Aquinas compares the meaning of ens and esse to currens and currere.

"For we signify one thing by saying [esse] 'to be,' and something else by saying [ens] 'that-which-is,' just as we also signify one thing when we say [currere] 'to run,' and something else by saying [currens] 'one running.'

“For [currere] 'to run' and [esse] 'to be' are signified in the abstract, just as [albedo] 'whiteness' is; but [ens] 'what-is,' that is, 'a being,' and [currens] 'one running' are signified in the concrete, as is [album] 'a white thing.'"

This ‘to be’ (esse) Aquinas takes to be the act of all acts and the perfection of all perfections.



The remark is taken to be in agreement with the comments I reported on Entry 01-0051.
