> is real: it's a construct in one's mind, and minds are just as real

This is a weird thing to say. Not all mental constructs are "real" in a meaningful sense.

[loup-vaillant]

No mental construct can exist without a cognition engine to run it. No idea can be thought without a mind to think it. Information has to be stored somewhere, and that somewhere is ultimately physical: a nervous system, a hard drive, a piece of paper…

When everything is real, the word doesn't mean anything anymore.

What does all this have to do with reality of objects themselves?
