Full Idea
If truth is congruence between a complex belief and a complex relation between objects in the world, this may work for Othello's belief about Desdemona, but it doesn't seem to work for the simple belief that an object exists.
Clarification
'Congruent' things are the same shape
Gist of Idea
Truth as congruence may work for complex beliefs, but not for simple beliefs about existence

Though Russell has an interesting and persuasive theory, this seems like a big problem. To have a complex belief about a complex of objects, you must first have beliefs about the objects (and that can't be acquaintance, because error is possible).
