Muller's themes have always to do with situations of human interaction. It is a question wether Muller intends to ridicule the human phenomenon. It appears to be more plausible to assume that he follows a line of thoughts that relates logical facts to illogical ones, without leaving the area of reality. For human reality is, contrary to received ideas, not logical.
C.B. Muller combines the mentioned situations of human interaction with the visualisation of mankind's ability to create frontierless thoughts about everything. Most of these thoughts stay in the heads of the people. In Muller's paintings they are partly visible, and refer, among other things by its strange arrangements, to the contrast between conditioned behaviour and total freedom of thinking.
