In philosophy the field of ontology considers what things exist, and what existence implies.[1]
For some philosophers, called 'deflationist', this question is linguistic, that is, it concerns the usage of expressions like 'At least one such-and-such exists'.[2] Such phrases are called quantifier expressions.[3]
For other philosophers, ontology concerns the actual existence of real things in the universe. The subject is complicated by discussion of issues like whether compound objects really exist, a question of mereology. For example, does a 'book' exist or only the 'pages' of the book. How do we draw the line between 'sensible' compound objects and silly ones like 'my nose and the Eiffel tower'?[4] Another confusion called 'Plato's beard' considers whether a statement like 'Pegasus is a flying horse' implies a belief in the existence of Pegasus. In general terms, is it true that statements, true or false, are about something?[5]
