question from class

Alright. So in class today we discussed correspondent truths and coherent truths. And that something is correspondantly true if it is true based on the world as it is. And coherence is true if it is true to the world as we know it to be. And something cannot be and not be at the same time. Like i can only be sitting on this chair at this second. I cannot be not sitting on it at the same time. It cannot be a chair and not a chair at the same time. But i was wondering if it were possible for a thing to be a thing and not a thing at the same time dependent on whether or not we assign it new meaning. Like say for instance, I have a book. It looks like a book, it has pages and a spine and words and reads like a book. But say i want to put my feet up and i assign the book new meaning as a foot stool. Is it still a book? It still looks like a book, but now it serves a new purpose, so is it a foot stool? Can it be both of those? Or once it serves a new purpose, dies it lose its old meaning? Just like when chelsea brought up the question today of Micheal Jackson being both black and white. He is still ethnically african american, however he appeared to be caucasian at the same time because of various alterations. So does that made him black or white? i suppose on the basis of color alone he is not both black and white. However bringing intoi account other truths he is both.

Is it possible for meaning to change the identity of an object?
