The self concepts of Mead and Kierkegaard respectively show striking similarities. A comparative analysis of the two self concepts is carried out. Similarities are indeed present at a structural level. Clear-cut differences appear when semantic deep structures of the concepts used by the two thinkers are included in the analysis. The observed differences are reflecting the fact that they drew their inspiration from widely divergent intellectual traditions, Kierkegaard from Christian theology, Mead from a darwinistically inspired world-view.
