Thank you for your detailed answer. I forgot to mention that I referred to a specific apple on a specific table and not to the term "apple" in general. But I assume the same principles you mentioned apply to that. Is there some kind of "proof" that I can decide on my own which atoms belong to an object? Your answer sounds very logical to me and I agree with you, but despite that I am looking for some kind of "proof". I am worrying that there might be an undiscovered scientific law or fact that says that this is not possible. I forgot to mention that I referred to a specific apple on a specific table and not to the term "apple" in general.

Hello, in my opinion objective reality exists and is the result of all science. I wanted to know or have opinions on the question whether it is valid to define material things in a way that is unusual but does not interfere with scientific facts i.e. contradict them and thus become invalid in objective reality. For example a defitiniton such as : "an atom is a molecule" would be invalid because it contradicts science. Now let's say I see an apple on a table. Would it be valid to say the following? "The apple I see also consists of the upper most atoms of the table". I think it is valid as a subjective opinion because it does not contradict science, i.e. this definition does not try to alter objective reality. I would be happy to have opinions on this. Thanks, Harris
