It being an established fact that the object and the subject, that are fit to be the contents of the concepts 'you' and 'we', and are by nature as contradictory as light and darkness, cannot logically have any identity, it follows that their attribution can have it still less.

Accordingly the superimposition of the object, referable through the concept 'you', and its attributes on the subject that is conscious by nature and is referable through the concept 'we', and contrariwise the superimposition of the subject and its attributes on the object, should be impossible.

This passage is drawn from Adi Sankaracarya's Brahmasutrabhasya.
