How much more just we would be in our judgment of men if we realised
that a man may be honestly two different men, and how this theory would
explain that which in every man of high organisation seems sometimes to
be contradictory! Aye, within five minutes some of us with mercurial
natures can remember to have been two entirely different men in two
entirely different worlds. Something said to us cheering or depressing;
some tidings announced, glad or sad; some great kindness done for us, or
some meanness practised on us have changed the zone, the pulsation, the
physiognomy, the physical, the mental, the spiritual condition, and we
become no more what we were than summer is winter, or midnoon is
midnight, or frosts are flowers.
