 Proof of 2. Whatever can be found in experience is some material being, extended in space, and so it has to have a multitude of spatially distinct parts. Therefore, it is many in respect of those parts. But what is many in some respect is not one in that respect, and what is not one in some respect is not absolutely one. Therefore, nothing can be found in experience that is absolutely one, that is, nothing in experience is an absolute unity.
