coherent, logical, and necessary  aspects  as well as
　　   the  adequate  and  applicable   aspects.   It  is  a
　　   comprehensive　　 scheme　　 in　　 which　　 there　　 is
　　   interconnectedness  through and through.  But we must
　　   start from somewhere  and Whitehead  does this on the
　　   sure  ground  of  human  experience.  He  says,  "the
　　   ultimate  facts of immediate  actual  experience  are
　　   actual  entities, prehensions, and  nexuus."(l5) They
　　   are, as it were, on display in every experience. They
　　   are interrelated terms in the immanent sense. Thus he
　　   says, "just as the relations  modify  the natures  of
　　   the relata, so the relata  modify  the nature  of the
　　   relation.  The relationship is not a universal. It is
　　   a concrete fact with the same con-

　　   creteness as the relata."(16) This  is  his  doctrine
　　   of relatedness  or mutual immanence, a doctrine which
　　   prevents  one from  isolating  or locating  an actual
　　   entity  in  any  well-defined  context.   The  actual
　　   entities  are the "final things of which the world is
　　   made up, "(17) and are the basis  of the relatedness.
　　   Thus  they cannot  be empty  or vacuous  actualities.
　　   They  "involve   each  other   by  reason   of  their
　　   prehensions  of each  other,"(18) or it is the nature
　　   of each being to be a potential  for every  becoming.
　　   Thus the togetherness  or unity of these entities  by
　　   virtue  of their prehensions is the fact of a nexuus.
　　   According  to  Whitehead,  a  prehension  involves  a
　　   "subject," the datum, and the subjective  form  which
　　   refers to the "affective" aspect of the "subject." As
　　   prehensions  are the order of becoming in nature from
　　   the smallest entity to the largest, the gradation  or
