  1. Extrapolating a hierarchy of building Block systems towards future neural network organisms.GerardJagersop Akkerhuis - 2001 - Acta Biotheoretica 49 (3).
    It is possible to predict future life forms? In this paper it is argued that the answer to this question may well be positive. As a basis for predictions a rationale is used that is derived from historical data, e.g. from a hierarchical classification that ranks all building block systems, that have evolved so far. This classification is based on specific emergent properties that allow stepwise transitions, from low level building blocks to higher level ones. This paper shows how this (...)

    Towards a hierarchical definition of life, the organism, and death.Gerard Ajm Jagers Op Akkerhuis - 2010 - Foundations of Science 15 (3):245-262.
  3. Towards a Hierarchical Definition of Life, the Organism, and Death.Gerard A. J. M. Jagers op Akkerhuis - 2010 - Foundations of Science 15 (3):245-262.
    Despite hundreds of definitions, no consensus exists on a definition of life or on the closely related and problematic definitions of the organism and death. These problems retard practical and theoretical development in, for example, exobiology, artificial life, biology and evolution. This paper suggests improving this situation by basing definitions on a theory of a generalized particle hierarchy. This theory uses the common denominator of the “operator” for a unified ranking of both particles and organisms, from elementary particles to animals (...)

    Explaining the Origin of Life is not Enough for a Definition of Life.Gerard Jagers op Akkerhuis - 2011 - Foundations of Science 16 (4):327-329.
    The comments focus on a presumed circular reasoning in the operator hierarchy and the necessity of understanding life’s origin for defining life. Below it is shown that its layered structure prevents the operator hierarchy from circular definitions. It is argued that the origin of life is an insufficient basis for a definition of life that includes multicellular and neural network organisms.

    The Issue of “Closure” in Jagers op Akkerhuis’s Operator Theory.Nico M. van Straalen - 2011 - Foundations of Science 16 (4):319-321.
    Attempts to define life should focus on the transition from molecules to cells and the “closure” aspects of this event. Rather than classifying existing objects into living and non-living entities I believe the challenge is to understand how the transition from non-life to life can take place, that is, the how the closure in Jagers op Akkerhuis’s hierarchical classification of operators, comes about.

    Definitions of Life are not Only Unnecessary, but they can do Harm to Understanding.Rob Hengeveld - 2011 - Foundations of Science 16 (4):323-325.
    In my response to the paper by Jagers op Akkerhuis, I object against giving definitions of life, since they bias anything that follows. As we don’t know how life originated, authors characterise life using criteria derived from present-day properties, thus emphasising widely different ones, which gives bias to their further analysis. This makes their results dependent on their initial suppositions, which introduces circularity in their reasoning.
