Living systems analysis includes both qualitative and quantitative sciences.
Qualitative living systems are treated well in James Millers Living Systems.
Philosophers have been trying since the 18thcentury to develop a science of society based on laws of nature. The physical sciences are based on (1) the identification of universal phenomena, the relation among them and their measures (quantification).
The universal phenomena of things that live are: matter, energy, information, and knowledge.
These phenomena have been identified and quantified. The quantification of living systems phenomena and their relations provide the basis of quantitative living systems analysis
The universal phenomena of knowledge and information are recent discoveries.
Quantification of knowledge and information are currently at the cellular level. The task before us is quantify knowledge and information at all levels from the cell up to and including humans and their organizations.
