Shaky constructions

Sammanfattning: I aim to examine what should be demanded of a constructivistic theory trying to describe the construction of a human belief-system. My claim is that such a theory cannot allow entities in the description of how a human being constructs the world he or she lives, that are not allowed in the act of constructing the life-world. I will argue that the only coherent theories describing this activity are either phenomenological or social. That is, theories where the description of the constructing and the construction of the theory itself are identical or the constructor of the theory is taken to live in the same or a similar life-world as the one described. To substantiate my claims I will closely examine the theory of radical constructivism. This theory can be described as an attempt to give a partly empirical description of a non-social construction of a life-world, from an observer's point of view. I will argue that the attempt is not successful.
