CHAPTER V
HABIT
Habit   is  our "best   friend  or  worst   enemy." We  are "walking    bundles of  habits."
Habit   is  the "fly-wheel  of  society,"   keeping men patient and docile  in  the hard    or
disagreeable    lot which   some    must    fill.   Habit   is  a   "cable  which   we  cannot  break."
So  say the wise    men.    Let me  know    your    habits  of  life    and you have    revealed
your    moral   standards   and conduct.    Let me  discover    your    intellectual    habits, and I
understand  your    type    of  mind    and methods of  thought.    In  short,  our lives   are
largely a   daily   round   of  activities  dictated    by  our habits  in  this    line    or  that.   Most
of  our movements   and acts    are habitual;   we  think   as  we  have    formed  the habit   of
thinking;   we  decide  as  we  are in  the habit   of  deciding;   we  sleep,  or  eat,    or  speak
as  we  have    grown   into    the habit   of  doing   these   things; we  may even    say our
prayers or  perform other   religious   exercises   as  matters of  habit.  But while   habit
is  the veriest tyrant, yet its good    offices far exceed  the bad even    in  the most
fruitless   or  depraved    life.
1. THE NATURE OF HABIT
Many    people  when    they    speak   or  think   of  habit   give    the term    a   very    narrow  or
limited meaning.    They    have    in  mind    only    certain moral   or  personal    tendencies
usually spoken  of  as  one's   "habits."   But in  order   to  understand  habit   in  any
thorough    and complete    way we  must,   as  suggested   by  the preceding   paragraph,
broaden  our     concept     to  include     every   possible    line    of  physical    and     mental
activity.   Habit   may be  defined as  the tendency    of  the nervous system  to  repeat
any act that    has been    performed   once    or  many    times.
The Physical    Basis   of  Habit.—Habit    is  to  be  explained   from    the standpoint  of
its physical    basis.  Habits  are formed  because the tissues of  our brains  are capable
of  being   modified    by  use,    and of  so  retaining   the effects of  this    modification    that
the same    act is  easier  of  performance each    succeeding  time.   This    results in  the
old act being   repeated    instead of  a   new one being   selected,   and hence   the old act
is  perpetuated.
