Geologische Aspekte zur Evolutionsthematik der Erdenentwicklung
Der Kausalitätsbegriff in seinem Verhältnis zum Vitalismus
The concept of causality in relation to vitalism
This hitherto unpublished part of the early work of Gerbert Grohmann (1897-1957) presents the philosophical contribution belonging to his doctoral thesis in natural sciences submitted in 1923 to the philosopher Hans Driesch (1867-1941) at the university of Leipzig, Germany.… Read More
Chronobiologie ist Ätherforschung
Chronobiology is etheric research
Research on the etheric world easily leads to evasive methods: to chemically and physically controlled laboratory experiments on dead substances or to psychological formulation of the concepts. The first method tries to objectify the etheric world; the second subjectifies it. The etheric world, however… Read More
Hygiogenese und Salutogenese Versuch einer (notwendigen) Begriffsdifferenzierung
Hygiogenesis and salutogenesis - an attempt at a (necessary) differentiation of concepts
The concepts salutogenesis and hygiogenesis originate from different basic considerations. Hygiogenesis means a systematic representation of autonomous regulations in the sense of a therapeutic physiology. Salutogenesis, however, represents a system… Read More
Über Methoden zur Erforschung hygiogenetischer Prozesse
On research methods of hygiogenetic processes
The processes bringing about health after illncss may be considered as metamorphoscs of those processes which generally enable health. As rhythm is one of the most essential conditions of life, we speak of hygiodynamics (maintenance of health) and hygiogenesis (healing) respectively. So… Read More
Geschichte und Problem des Höherentwicklungsbegriffs
The history and problem of the idea of evolution
The usual picture of the phylogenetic process is that there were first single-celled bacteria-like organisms followed by multicellular,»lower«and later»higher«, rather complex and differentiated forms of life. This succession of evolutionary changes has often been called»evolutionary… Read More
Zur evolutiven Ausbildung von Blüte und Frucht bei den Hahnenfußgewächsen
Concerning the evolutionary development of the blossom and fruit of the Ranunculaeeae
The fruit formation of the Ranunculaceae - evolutionarily early representatives of the angiosperms - is taken as a motif in examining the evolutiona1y path of the formation of both the angiosperm blossoms, exposed as they are to their surroundings, and… Read More
Korrelation von Sprossgestalt und Blattgestalt annueller Dikotyledonen
Correlation of the shapes of the shoot and leaf of annual dicotyledons
That the shape of a plant changes qualitatively and quantitatively during growth was noted as early as Aristotle. He tried to understand this process with the help of four»causes«(aitia) and four»rnotions«(kinesis). He thought that the formative force proceeds from… Read More
Streptocarpus mit Brutblatt
Streptocarpus with a brood leaf
In the genus Streptocarpus (Gesneriaceae) the usual generation of new leaves on the shoot is more or less replaced by a generation of new leaf parts on the bases of abundant leaves. This indicates a homology between shoot growth and leaf growth. ‚Interesting malformations are described which could help… Read More
