By "objects", Wittgenstein did not mean physical objects in the world, but the absolute base of logical analysis, that can be combined but not divided (TLP 2.02–2.0201). According to Wittgenstein's logico-atomistic metaphysical system, objects each have a "nature," which is their capacity to combine with other objects. When combined, objects form "states of affairs." A state of affairs that obtains is a "fact." Facts make up the entirety of the world. Facts are logically independent of one another, as are states of affairs. That is, one state of affair's (or fact's) existence does not allow us to infer whether another state of affairs (or fact) exists or does not exist.
