APS treats organisation as a real and scientifically investigable feature of living systems.
Organisation does not refer to hidden vital forces, supernatural properties, or mysterious holistic essences. It refers to the structured relations, regulatory dynamics and continuity-preserving processes through which biological systems sustain themselves.
Living systems persist because their activities are organised in ways that maintain viability across changing conditions.
Organisation is therefore neither reducible to isolated mechanisms nor opposed to mechanistic explanation.
APS interprets organisation as natural, material, mechanistically realised and explanatorily indispensable.
