Living organisms are characterized by two properties that make them different from other physical systems: they are medium in size and functionally heterogeneous internally. Because they are smaller than planets and larger than atomic nuclei, and because there are a large number of interacting processes occurring within them, organisms are at the nexus of a very large number of individually weak determining forces.

It is the social mediation of individual biological phenomena that turns a single day's incapacity from the flu into the loss of a job for an already marginalized worker, with consequent catastrophic economic failure and a disintegration of health and the general conditions of life. Beyond the transformation of biological needs into forms that are specific to different times and places, the kind of social interaction that is biologically possible for the human species has an even more powerful property, the property of negating individual biological limitations.
