Abstract
In answering his primary question, What is existence?, Dom Mark draws an equation between "assertibility," "existence," "being," and "reality": "...this assertibility is precisely what we mean by existence or being or reality". And "assertibility," I take it, implies and is really identified with intelligibility; for all being is "assertible" just because and in so far as it is intelligible. So far, so good. The real difficulty is in Dom Mark's identification of "existence" and "being": "The existence of X, Y, and Z simply is X, Y, and Z, but looked at as wholly dependent". And again: "...existence or being refers to every knowable object under that aspect which each has, of complete dependence on a source from which they are derived" p. 22). It is quite clear that in this doctrine existence is not the act of a dependent being, whereby that being is; "existence" is that very being considered as dependent. Dom Mark has firmly grasped and well explained the character of the created existent, as such, but at the same time he has identified the created existent with created existence--the creature, as such, with the creature's act of existence.
