What is life? The question has stayed open through a century of detailed empirical
progress. I argue the impasse is not a gap in empirical knowledge. It
is a confusion about what the noun life refers to. The standard treatments fail
in a common way. They assume the noun applies either to a hidden substance
behind the visible organisation of living matter, or to a bundle of features and
processes attributed to living systems. Substance accounts, in their historical

Read moreWhat is life? The question has stayed open through a century of detailed empirical
progress. I argue the impasse is not a gap in empirical knowledge. It
is a confusion about what the noun life refers to. The standard treatments fail
in a common way. They assume the noun applies either to a hidden substance
behind the visible organisation of living matter, or to a bundle of features and
processes attributed to living systems. Substance accounts, in their historical
vitalist forms, have been rejected. Property accounts, in their thermodynamic,
autopoietic, emergentist, natural-kind, and operational variants, leave
a persistent residue. However complete the description, the question what
the noun picks out beyond the attributes returns.
I argue for a third position. The noun life applies directly to a specific form of
ordered organisation, where the organisation is the referent and not a property
of a separate system. This treatment of names as applied to ordered form
is developed in classical Indian philosophy under the term nāma-rūpa. It operates
without dispute for many ordinary nouns. A pot is clay in a form. A
ring is gold in a form. Applied to life, the position yields the following ontology.
Life is the form of order that is recursively self-maintaining, bounded,
and lineage-transmissible. The three features are constitutive of the kind of
order. They are not external criteria the order must satisfy.
The position does the work that property accounts leave undone. The autopoiesis
tradition approached the move and stopped one step short of taking
it. Natural-kind and operational-list accounts cannot generate it. The worry
that biology is in the process of explaining life away dissolves once the noun
is parsed correctly. Biology has been mapping the ordered organisation the
noun names all along.
