The differences between natural and artificial life. Towards a definition of life

Published 2010-12-13, updated 2011-11-30Version 2

It is high time to openly and without finalism define the dangerous but needed term 'purposeful information', whose quantity is an Eigen information value. Using the term 'biological information' in its stead forces one into an uncomfortable detour. I propose such a definition based on the generalized notions of 'information' and 'encoding'. Next, the properties of the spontaneous process of collecting purposeful information are investigated. In effect, the properties of this process: the goal 'continuation of existence', reproduction and Darwinian mechanism are derived which suggest, that it is the natural life process. A 'natural identity criterion' appears in this process for an evolving object, that is connected to a 'small change tendency'. Likewise, 'hereditary information' is defined. Artificial life is constructed by living objects, is a part of natural life process and its properties are not an effect of its internal restrictions but of external assumptions.
