Constructivist Foundations is an international triannual peer-reviewed academic journal that focuses on constructivist approaches to science and philosophy, including radical constructivism, enactive cognitive science, second-order cybernetics, biology of cognition and the theory of autopoietic systems, and non-dualizing philosophy[clarification needed].
It was established in 2005 and the editor-in-chief is Alexander Riegler (Free University of Brussels).
The inaugural issue of Constructivist Foundations was presented at the 2005 meeting of the American Society for Cybernetics.
Originally, the articles in CF were meant to explore mainly von Glasersfeld's radical constructivism.
"[4]"In very general terms, constructivist approaches can be said to support the idea that mental structures such as cognition and perception are actively built by one's mind rather than passively acquired.
