So all complex objects in the world are, at the most fundamental level, made up of simple un-analysable objects which are denoted by 'names'.
Combinations of simple objects constitute 'states of affairs'.
States of affairs are denoted by 'elementary propositions'.
Why couldn't a significantly developed state of affairs have an elementary proposition such as 'table', or 'green'?
I am aware of the thought experiment of a universe consisting of only, say, yellow and green. It is argued that the existence of green in one place would contradict the existence of yellow in another and since Wittgenstein asserts that elementary propositions are independent of one another this cannot be the case.
However, 'green' is not the same as 'green exists in place A' which would be a complex proposition, and would contradict 'yellow exists in place A'.
'Green' doesn't result in a contradiction of 'yellow'.
To reiterate my question: why can't elementary propositions be words such as 'table' or 'green'?
