A day?  A few hours?  A few milliseconds, a
few . . . ?  We can say for sure that the past
is at least infinitely large, if not exactly how
large.  The same can be said of the future.
But how large is the present?  Or . . . . how
small, insignificant and non-existent could
the present really be?

Actually, the present is composed of strands
of the past and strands of the future like
grey is really composed of black strands
and white strands.  And you and I are 
actually living in the past and the future at
the same time.  The past, the present, and
the future are one and the same.  Your past
life, and present life, and future life, are
one, and the same.  Déja vu.

Quantity vs Content

Content is irrelevant.  A misnomer.  A
nonentity.  It is quantity that lends existence
any individuality, that gives it any color or
chemistry.  Quantity, not content, that makes
black black, and white white, and grey grey.
And that quantity is one, a state of being.
And two, a number, in a secondary way.
