“As conscious beings, we exist only in response to other things, and
we cannot know ourselves at all without knowing them.
Moreover, there is nothing in theory, and certainly nothing in
experience, to support the extraordinary judgment that it is the
truth about himself that is the easiest for a person to know. Facts
about ourselves are not peculiarly solid and resistant to skeptical
dissolution. Our natures are, indeed, elusively insubstantial —
notoriously less stable and less inherent than the natures of other
things. And insofar as this is the case, sincerity itself is bullshit.”
