No, the scalpel doesn’t actually exist except as an idea in the mind that is attached to, thus it can’t be said to really exist in any way. It is empty of self existence (svahbhava), as is our own mind. Nothing has fundamental essence or identity
Sorry, I'm not a subjective idealist or a solipsist. I believe god consciousness is the final arbiter. And that we can expand our human consciousness to god consciousness. So I'm partial to objective idealism instead.
