Write your reply.

assistant: There is no substantial difference.
 Certainly - but it takes a human brain to speculate as to what it was
 doing, nevertheless, even before there were human brains to speculate.

 Certainly, and what physical matter does... is entirely dependent upon
 how it is observed doing it.  If I existed as a frog, I might have a
 different view entirely about what matter does.  And whether or not
 matter does it the way it does because of an objectivation, or whether
 it does it because I observe that it does it.

 But, WE are also a property of matter.  You can't ask the wind what
 temperature it is, because they are both properties of the atmosphere.
 As I mentioned - we are also a property of matter.  And we are flawed
 in the sense that we do not see our progenitor clearly enough to know
 what "time" it really is - even if we are using an atomic clock to do
 it.  Relative to a moment before, we can be exact, but moment by moment
 might stretch to eons without our perceptions, even matter itself may
 be changing its behavior from moment to moment - we cannot tell it.  It
 is not a confusion with the brain's subjective sense of time's movement-
 it's that _matter's_ objectivity itself is drawn into question.  Atoms
 have a nucleus with one or more protons revolving around it, all at a
 determined frequency.  We can do amazing and wonderful things with this
 information - but we must not forget that it is only in the world of
 appearances that it is happening.  What means do we have to determine
 whether or not these apparent regular patterns to matter really are
 regular?  Because we are also a product of this same universe, it
 becomes impossible for us to tell whether we are looking at regularity,
 or that we are only seeing an _apparent_ regularity.  Our objectivity
 is, and always shall be, limited by the universe in which we exist.
