|Ontology: is the set of material or immaterial objects, of which a theory assumes that it can make statements about them. According to classical logic, an existence assumption must be assumed. In other fields of knowledge, the question of whether relations really exist or are merely mental constructs, is not always regarded as decisive as long as one can work with them. Immaterial objects are e.g. linguistic structures in linguistics. See also existence, mathematical entities, theoretical entities, theoretical terms, reality, metaphysics, semantic web.|

Ontology/Sellars: at the end there is an ontology in which there are only processes. Absolute processes: where we are not anymore talking about objects. ("It is raining"), the word "it" here represents no object.
Strawson had also contemplated this, and dropped it for the reason, among others, that there are not always objectless processes such as lightning or bangs, to be identified without reference to other objects.
