This commentary considers Sander's contributions to our thinking about recognition, with particular emphasis on his idea of rhythmicity as a major organizing principle. The author suggests ways in which rhythmicity contributes to our apprehension of and participation in the third, that aspect of the intersubjective relationship which is cocreated and yet lawful. Both Sander's research and his contemporary reflections represent an important effort to unite our understanding of energy and information as complementary aspects of the same communication process.
