QUOTE : No man is an island-he is a holon. A Janus-faced entity who, looking inward, sees himself as a self-contained unique whole, looking outward as a dependent part. His self-assertive tendency is the dynamic manifestation of his unique wholeness, his autonomy and independence as a holon. Its equally universal antagonist, the integrative tendency, expresses his dependence on the larger whole to which he belongs: his 'part-ness'. The polarity of these two tendencies, or potentials, is one of the leitmotivs of the present theory. Empirically, it can be traced in all phenomena of life; theoretically, it is derived from the part-whole dichotomy inherent in the concept of the multi-layered hierarchy; its philosophical implications will be discussed in later chapters. For the time being let me repeat that the self-assertive tendency is the dynamic expression of the holon's wholeness, the integrative tendency, the dynamic expression of its partness.
