APS_LD reframes life detection in terms of viability-oriented, constraint-closed biological organisation, arguing that the detection of life should focus on identifying systems that actively sustain their own persistence rather than relying solely on trait lists or specific molecular markers.
-
This article clarifies what counts as evidence for life in the APS framework. It distinguishes definition, diagnosis, and evidence, and shows that biological evidence is not behavioural but organisational—indicating viability-oriented, constraint-closed organisation across scale.
-
Cognitive Integration (CI) is a core diagnostic dimension in APS, expressing the degree to which a system coordinates its activity across processes, time, and scale in sustaining its own viability. CI distinguishes simple reactive adjustment from integrated, system-wide regulation, without presupposing representation or consciousness.
-
This article applies the APS diagnostic framework to a plant system, demonstrating how viability-oriented organisation can be evaluated in practice. Using perturbation and the three diagnostic dimensions—Viability Gradient (VG), Normativity Gradient (NG), and Cognitive Integration (CI)—it shows how plant activity reveals biological agency without requiring neural or representational explanations.
-
APS distinguishes between malfunction within a system and the collapse of the organisation that sustains its viability. This article applies the APS diagnostic framework to cases of breakdown, showing how failure is identified when viability-oriented organisation can no longer be maintained across time and scale.
-
APS provides an operational method for diagnosing biological systems by evaluating viability-oriented organisation rather than identifying traits or components. This article presents a step-by-step diagnostic procedure based on perturbation, organisational response, and three diagnostic dimensions: the Viability Gradient, Normativity Gradient, and Cognitive Integration.
-
The Normativity Gradient (NG) is a core diagnostic dimension in APS, expressing the degree to which a system’s activity is oriented toward sustaining its own viability. Rather than invoking intention or evaluation in a mental sense, NG captures the endogenous organisation through which systems differentiate between conditions that support or degrade persistence.
-
The Viability Gradient (VG) is a central diagnostic dimension in APS, capturing the degree to which a system sustains its own persistence under changing conditions. Rather than treating life as a binary property, VG provides a continuous measure of how effectively viability-oriented organisation is maintained across time and scale.
-
APS reframes biological diagnosis as the evaluation of viability-oriented organisation rather than the identification of traits, mechanisms, or components. This article defines diagnosis within the APS framework and clarifies how it differs from traditional biological and medical approaches.
