The Bioethics of the "Crazy Ape" collects a wide range of bioethical topics. Bioethical questions are eternal by nature, although our technologized times transform old issues in forms never before experienced. Just like the famous scientist Albert Szent-Gyoergyi believed in his time, we also believe that all the contributing authors recognised their moral responsibility in adding new approaches to the continuum of each debate. Although this responsibility has became increasingly complex, we must avoid to become barriers of the scientific development. Bioethics as an applied field of philosophy should always try to establish a framework for a sustainable world: in daily clinical practice, in cases of human experiments, and (not least) in the natural environment.
