[quote=“Stanton, post:11232, topic:141”]Not when we fill it with meaning.

Yes, but that’s not what I mean with an ‘empty concept’
Take your reasoning and replace ‘art’ by ‘God’
This is what you said:
“If someone thinks it is art, it is art at least for him. And nobody can take this away from him as long as he believes in it. So, yes everything can be art (…)”
Now we have someone who thinks something (the image in his head or an object) or someone (he himself or another person) is God. We can say:
“If someone thinks it (he) is God, it (he) is God at least for him. And nobody can take this away from him as long as he believes in it. So yes, everything (everybody) can be God (…)”
We cannot take this idea away from him, but we most probably will conclude there’s something wrong with the guy (or the girl).
What is wrong with this idea, is that it conflicts with our concept of ‘God’: we don’t know exactly who or what God is, our ideas have changed over the years, centuries, millenia (therefore there’s a multitude of definitions and thousands of books explaining what these definitions mean), but every even remotely sensible concept is denied by this man’s representation: his idea implies that God can be anybody or anything, no matter what. If a thing or an idea can be anything, no matter what, it’s nothing in particular, and that what’s called an ‘empty concept’. This reasoning is also used to illustrate the idea that it was Duchamp’s intention to show that the concept of art popular among his contemporaries was ‘empty’, would lead art into a dead end street.
The same things can be said about other concepts, like for instance truth: if everything, no matter what, can be truth, it does no longer make sense to talk about true or false, right or wrong.
