The relationship between phenomenology and the sciences is of complex nature. In particular, the transcendental phenomenological position seems to promote skeptical reservations about the scientific attitude. Phenomenological anthropology and psychology, however, are an exception. The work of the Spanish philosopher Javier San Martin addresses the relationship of Husserlian phenomenology to these two particular sciences. In this paper, the work of Navarrese will be revisited as an occasion to reflect on the relationship between phenomenology and the sciences. In the first part, San Martin’s philosophical approach is presented and put in relation to its counterpart, namely ratiovitalism, which has dominated phenomenological research in the Spanish-speaking world throughout the last decades. The second part is devoted to the question of whether phenomenological transcendentalism is compatible with anthropological research. It also describes San Martin’s contribution to cultural philosophy. The relationship between phenomenology and psychology is discussed in the third part. San Martin develops a critical account of empiricist psychology which he confronts with his proposal for a ’posttranscendental’ psychology that is based on the critique of psychologism and representationalism. The last section compares San Martin’s idea of anthropological and psychological science with other forms of scientific theory which contribute to phenomenological methodology in empirical research.
