    Compatible Operations on Residuated Lattices
    with J. L. Castiglioni
    Studia Logica 98 (1-2): 203-222. 2011.
    This work extend to residuated lattices the results of [ 7 ]. It also provides a possible generalization to this context of frontal operators in the sense of [ 9 ]. Let L be a residuated lattice, and f : L k → L a function. We give a necessary and sufficient condition for f to be compatible with respect to every congruence on L . We use this characterization of compatible functions in order to prove that the variety of residuated lattices is locally affine complete. We study some compatible func…Read more

    Normativität des Lebens - Normativität der Vernunft? (edited book)
    with Markus Rothhaar
    De Gruyter. 2015.
    A new controversy has arisen in practical philosophy concerning the principles of normativity. Conceptual approaches in the Kantian tradition, which derive the fundamental norms for human coexistence from formal determinants of reason are countered by models that have revived the notion of an authentic normativity of nature or of life, following Aristotle and Thomas of Aquinas. The volume brings together advocates of both positions.

    Blurring nature at its boundaries. Vague phenomena in current stem cell debate
    Medicine, Health Care and Philosophy 20 (3): 373-381. 2017.
    This paper illuminates the explanatory role of vagueness und species membership against the background of scientific developments in recent stem cell research. With the help of the Neo-Aristotelian concept of “life form naturalism” ontologically vague entities such as stem cells, all above induced pluripotent stem cells, could be described as necessary constituents for the correct sorting and naming of natural processes and its bearers. Furthermore this specific assessment allows drawing some im…Read more

    This paper is referring to Fichte’s ambivalent notion of nature. For Fichte, nature is something that needs to be formed. This formability is an evidence of the imperfection, even depravity of an unformed and therefore unfree nature. Fichte seems to allude indirectly on Martin Luther and the Reformation tradition. Accordingly, nature – which is in itself evil or will become evil – is a state from which men had to step out. The affinity to Rousseau’s picture of nature is obvious. Finally, the art…Read more

    Relatively compatible operations in BCK-algebras and some related algebras
    with N. Lubomirsky and W. J. Zuluaga Botero
    Logic Journal of the IGPL 25 (3): 348-364. 2017.
    Let |$\textbf{A}$| be a |$BCK$|-algebra and |$f:A^{k}\rightarrow A$| a function. The main goal of this article is to give a necessary and sufficient condition for |$f$| to be compatible with respect to every relative congruence of |$\textbf{A}$|⁠. We extend this result in some related algebras, as e.g. in pocrims.

    Aristotelian Naturalism: A Research Companion (edited book)
    Springer. 2020.
    This book features many of the leading voices championing the revival of Neo-Aristotelian Ethical Naturalism in contemporary philosophy. It addresses the whole range of issues facing this research program at present. Coverage in the collection identifies differentiations, details standpoints, and points out new perspectives. This volume answers a need: AN is quite new to contemporary philosophy, despite its deep roots in the history of philosophy. As yet, there are many unanswered questions rega…Read more

    On Hilbert algebras generated by the order
    with J. L. Castiglioni and S. A. Celani
    Archive for Mathematical Logic 61 (1): 155-172. 2021.
    In this paper we study the variety of order Hilbert algebras, which is the equivalent algebraic semantics of the order implicational calculus of Bull.

    Der manipulierbare Embryo (edited book)
    with Markus Rothhaar and Roland Kipke
    Brill Mentis. 2018.
    Der moralische Status menschlicher Embryonen ist und bleibt umstritten. Zugleich gibt es immer neue und tiefergehende biotechnologische Möglichkeiten, Embryonen zu manipulieren. Das betrifft insbesondere ihr Entwicklungspotential und die klare Zuordnung zur menschlichen Spezies. Dieses Buch untersucht, welche Auswirkungen diese neuen Manipulationsmöglichkeiten auf die Tragfähigkeit der Argumente haben, mit denen ein herausgehobener moralischer Status des Embryos begründet werden soll: d…Read more

    This report presents the current state of research in the debate on embryo protection. On the basis of scientific findings on species membership and the capacity of human embryos to develop properly, the report examines the extent to which these empirical facts influence the debate on the legal status of the human embryo. At the end of the article, the authors present the options for the further discussion with regard to the German Embryo Protection Act.

    Neoaristotelische Tugendethik
    In Christoph Halbig & Felix Timmermann (eds.), Handbuch Tugend Und Tugendethik, Springer Fachmedien Wiesbaden. pp. 333-348. 2021.
    Die neoaristotelische Tugendethik ist der Versuch, die klassische ethische Theorie des Aristoteles für aktuelle Fragen der praktischen Philosophie fruchtbar zu machen. Deren Vertreterinnen und Vertreter setzen dabei auf ein Erklärungsmodell, das Tugenden als situationsübergreifende Charaktermerkmale und intellektuelle Dispositionen, deren Einübung uns Menschen als rationale Wesen von Natur aus zukommt, in sein Zentrum stellt. Im Zentrum des Ansatzes steht die Behauptung, dass es notwendigerweise…Read more

    In this paper I give an overview about the general implications of issues of human nature within the field of human enhancement, especially paediatric neuro-enhancement. The first section of my contribution deals with a certain intertwining of human enhancement and the intrinsic claims of human nature showing that the concept of human nature still plays a crucial role in the debate on human enhancement. Subsequently, I take a step towards analysing of several childhood-related influences on thos…Read more
