Early scientific thinking was holistic, but speculative -- the modern scientific temper reacted by being empirical, but atomistic. Neither is free from error, the former because it replaces factual inquiry with faith and insight, and the latter because it sacrifices coherence at the altar of facticity. We witness today another shift in ways of thinking: the shift toward rigorous but holistic theories. This means thinking in terms of facts and events in the context of wholes, forming integrated sets with their own properties and relationships,

Systemicity is imposed as a set of rules binding the parts among themselves. But these rules do not constrain the parts to act in one way and one way only; they merely prescribe that certain types of functions are carried out in certain sequences. The parts have options; as long as a sufficient number of sufficiently qualified units carry out the prescribed tasks, the requirements of systemic determination are met.

Opposed to atomism and behaviorism, the systems view of man links him again with the world he lives in, for he is seen as emerging in that world and reflecting its general character.
