14、alanffys General Systems Theory General Systems Theory concepts of organization, non-summative wholeness, control, self-regulation, equifinality, and self-organization, are as valid in the social and behavioral sciences as they are in the biological.

He based his approach on the phenomenal assumption that t

Then he postulated two biological principles, namely, the maintenance of the organism in the non-equilibrium, and the hiera
