    The Biological and Philosophical Definitions of Life.M. Jeuken - 1975 - Acta Biotheoretica 24 (1-2):14-21.
    A distinction must be made between various levels of thought. For a definition of life the formulation on the level of natural sciences,i.e. the biological definition, will not be the same as the philosophical expression. The biological definition is based on thephenomenon of life, the appearance, and considers the molecular structure and functions of a cell. The philosophical definition regards thebeing and it is proposed to consider life as transcendental. It is argued that there is no opposition between these definitions, (...)

    The Concept “Individual” in Biology.M. Jeuken - 1952 - Acta Biotheoretica 10 (1-2):57-86.
    Dieser Aufsatz ist eine Besinnung auf den Begriff Individuum, wie dieser in der Biologie gebraucht wird, und er beabsichtigt, den Inhalt dieses Begriffes theoretisch zu begründen. Es ist aber unmöglich für die nähere Bestimmung des Begriffes Individuum von der etymologischen Bedeutung „unteilbar” auszugehen, weil die biologischen Individuen nicht immer unteilbar sind. Beim Suchen nach einem richtigen Untersuchungsverfahren wird zunächst dargelegt, wie diese Untersuchung wesentlich ein Teil der theoretischen Biologie, also der Wissenschaft, ist, wenn man auch von deutlichen Zusammenhängen mit der (...)

    A Note on Models and Explanation in Biology.M. Jeuken - 1968 - Acta Biotheoretica 18 (1-4):284-290.
    In biology a great variety of models can be distinguished: there is a gradation scale from the more realistic to the more idealistic ones. The place of a model on this scale depends on the role of the fundamental ideas, apriorisms and empirisms, which inspire the direction of thought. The relation between reality, models and explanatory theory is worked out. The interplay between model and ideas makes it understandable why in biology several kinds of explanation are possible.

    Function in Biology.M. Jeuken - 1958 - Acta Biotheoretica 13 (1):29-46.
    In this paper we intend to propose a definition of function in biology. First we delimitated the problem and pointed out that a definition must not be related to hypotheses such as the causal connexion between form and function, phylogenetics or evolution, but that only the existence of functions is to be considered. The elements to be expressed in the definition are: the relation of function to form, the dynamic character, the integration into the activity of the total organism, the (...)

    Thinking About Mind and Matter From Biology.M. Jeuken - 1983 - Acta Biotheoretica 32 (2):79-92.
    In biology, man is an object of research; therefore the question might be asked whether inspirations can go from biological data to the reflections on the mind-matter relation in man. The social aspect of man, as treated by sociobiology, is left out of consideration. The knowledge that man is mind, or has a mind, is no result of biological research. It is a datum from philosophy. The biologist, however, is living in a culture which knows about the mental character of (...)
