Editing Cogito, ergo sum (section)

=== Bernard Williams ===
Williams himself claimed that what we are dealing with when we talk of thought, or when we say "I am thinking," is something conceivable from a [[Grammatical person|third-person]] perspective—namely objective "thought-events" in the former case, and an [[Objectivity (philosophy)|objective]] thinker in the latter. He argues, first, that it is impossible to make sense of "there is thinking" without relativizing it to ''something.'' However, this something cannot be Cartesian egos, because it is impossible to differentiate objectively between things just on the basis of the pure content of consciousness. The obvious problem is that, through [[introspection]], or our experience of [[consciousness]], we have no way of moving to conclude the existence of any third-personal fact, to conceive of which would require something above and beyond just the purely subjective contents of the mind.<ref name=":1">{{Cite book|last=Williams|first=Bernard Arthur Owen|url=https://books.google.com/books?id=eiTXAAAAMAAJ&q=%22there+is+thinking%22|title=Descartes: The Project of Pure Enquiry|date=1978|publisher=Penguin Books|isbn=978-0-14-013840-5|language=en}}</ref>
