The article discusses the cosmological polarity in the Solomon Islands. It aims to show that Anglican Arosi's management of knowledge and ignorance shows a transformative reproduction of social polarity. It argues that the key to trace continuity within historical change is antropological attention to ontological premises of cosmology. The author offers a methodological precept of Fredrik Barth, as an alternative to Roger Keesing's presupposition of socio-cultural processes of depletion.
