Nevertheless the accident of seeing two objects
at the same moment, and the accident of seeing them in the same place
are two           or distinguishable causes: and the true practical
general law of association is this; that whatever makes certain parts of
a total impression more vivid or distinct than the rest, will determine
the mind to recall these in preference to others equally linked together
by the common condition of contemporaneity, or (what I deem a more
appropriate and philosophical term) of continuity.
