In my developmental approach, I outlined 3 distinct types of integration. Integral 1 related to the dynamic two-way integration of the "horizontal" polarities in development i.e. external and internal. Thus at each stage, successful integration required that an appropriate balance be maintained as between out-in i.e. integration of the (internal) self with respect to the (external) world and in-out i.e. integration of the (external) world with respect to the (internal) self. Integral 2 related to the corresponding dynamic two-way integration of the "vertical" polarities i.e. whole (collective) and part (individual). Thus between "higher and "lower" stages, successful further development required that an appropriate balance be maintained as between top-down i.e. integration of the - relatively - lower (part) with respect to the higher (whole) stages and bottom-up i.e. reverse integration of the higher (whole) from the lower (part) stages.
