This article situates the phenomenological-hermeneutical framework around the other and develops the hypothesis that the issue of intersubjectivity is central in understanding the fundamental categories related to any thought regarding alterity which are proposed in philosophy, in literatura, and in socio-political discourse, since it implies a central questioning about the analogy. Assuming the work of E. Husserl, and especially the contemporary comments on Phanomenologie der Intersubjektivitat, we advance toward an interdisciplinary focus of the 'other' and the 'alter ego' -proper to an analysis of the human experience-, demonstrating that the experience of sociability is forged from the original life experiences that refer to a determined way of understanding the analogic relationship between the self and the other and the others.
