`  ::You're the one who brought up all that stuff about ``zero point of entropy transfer``, which we now see is irrelevant and wrong: ``Entropy transfer (between bodies) must be understood before entropy content (as a property of a body) can be understood, because the zero-point of entropy transfer is well defined, while the zero-point of entropy content is arbitrary.`` In fact, it's entropy content that's well-defined, whereas entropy transfer is not meaningful because entropy is generally not a conserved quantity.  `
