3.4 A proposition determines a place in logical space. The existence of this logical place is guaranteed by the existence of the constituent parts alone, by the existence of the meaningful proposition.

That is, by the existence of “des sinnvollen Satzes.”

Noteworthy here is the apparent equation of the constituent parts and the meaningful proposition. But this might not be surprising if the proposition has been whittled down to an imperceptible commonality among various sentences and “the constituent parts” are simply possibility spaces. What we seem to have are possibilities, and of course each possibility guarantees the existence of a space for it in logical space. Because what follows “of course” in that sentence is a tautology.
