I seem to have argued my way to a point, were every time I use a personal pronoun, I do not know what it means.  This is a legacy problem.  Perhaps we can overcome it.  But it won’t do to try to ring-fence ‘I’ or ‘you’.  One of the biggest pressures on preserving these fictive selves is the issue of moral responsibility.   We insist that adhere to the ‘individual’, and we are bad at recognizing collective responsibility, though we seem to have gotten a bit better at that lately.
