Chreode
Chreode or Kreode ( Greek. : Chre - "it is necessary" and hodos - "way", "path") is a neologism that primarily by the biologists Conrad Hal Waddington was coined. It describes the development process of a cell during growth into a special organ. As a probabilistic term, it can be explained using a metaphor: If a ball lies in a landscape, it will take on the shape to best fit into the landscape - in other words: to find its state of rest. This is also a teleological approach, according to which the cell tries to achieve a goal (e.g. the development from the cell to the embryo).
The term chreode is also used secondarily in recent social science and educational research. According to Edmund Kösel , this means the development of the learner within a learning unit, whereby the term chreode is closely linked with the term subjective didactics . So it is not a continuous process like in biology, but rather a development process. Similarly, the term Kreode was used by Jean Piaget with reference to Waddington .
Even Jean-Baptiste Barrière uses the term chreode tertiary in similar form: here the chreode the part of a loop to the music in their development goes through (units for computers, 1983), with which a similar definition as is done in education.
The biologist Rupert Sheldrake uses the term in his unrecognized theory of morphic fields and describes a development path in the shaping of living beings and social systems.
application
Due to its very abstract construction and metaphysical terminology, "chreode" is found primarily in specialist literature as a linguistic term. This is also used when one wants to explain development lines or structural patterns within a loop in more detail.
