Sorry, but it's a concept, not an object. You're using a connotation of existence associated with the physical reality of objects. Identity is a mental construct. Like god. Or Middle Earth. I see your point in the same light as Anselm's Ontological argument. It's symantically incorrect. Anyway, I thought it was clear that I meant a "permanent identity", but perhaps not. I should have been more clear. Just trying to get an idea down. But thanks for the feedback .

@towkneed "The physical reality of objects" is nothing but a concept in your mind. Each object of which you are aware is also nothing but a concept in your mind. You are correct in taking it that what you meant by "permanent identity" is far from clear to me. Thanks for engaging.

@anglophone It's a concept shared at some level by most except perhaps sollipsists. Outside of mathematical proof what we mean by "objective" truth/reality cannot be anything other than the consensus of subjects, as all observation and perception is done by subjects. Saying something that only you experience is " real" is not a consensual "real". As a psychiatrist might say, "I'm sure it's real to you".

I got there from Hegel

@towkneed Congratulations. The only person ever to understand Hegel other than Frau Hegel!

@Geoffrey51 I always thought Hegel was a terrible writer. But I always read translations so I couldn't really judge.
But Marx was a Hegelian, and he was probably the most lucid writer ever despite translation. Of course- not speaking German - I could be wrong. Although I can't imagine the theory of surplus value could loose anything in translation.

@towkneed nothing wrong with Marx whether one agreed or disagrees. You know exactly what he was saying.

I suspect one needs to understand Hegel from the German but even then he apparently made words up. Schopenhauer was certainly not a fan and frequently castigated his writing.
