This is a mistake that you should not have made. When I talk about conceptual relativity I don't mean that there are no fundamental truths. I mean that we have such limited cpacities that we cannot walk around thinking that we can declare something to be a fundamental truth that we completely understand. Look a prepositions... A preposition (usually) refers to relative position of objects (objects of thought.) So anytime you mention position a preposition might be inferred. Since many things from our discourse about the real world-universe exist or take place somewhere that means that position may be inferred or even explicitly detailed in much of our comments. Many ideas which take place in our minds are stories that deal with place. And (this is where the trap door opens underneath your authoritative declaration) since we can use metaphor to describe ideas that means that most of our ideas contain references that can be inferred or which are explicitly implied to refer to relative positioning. So while the list of propositions may be conveniently finite, the number of possible inferences or implications of the character (or category) of relative position are uncountable. (According to my metaphor your authoritative declaration about the small unexpanding set of words that constitute the category of prepositions has been de-elevated. Even if it is technically true that there are only a few prepositions the number of phrases and sentences that can refer to the character that a preposition defines are uncountable.)
