The sharing of mooded presence in the world is what one could call a union or merging of souls, a common notion in the context of thinking and poetry about love, affection, friendship and suchlike. The human soul has to be thought as the openness of human being to the world, and this openness is, in the first place, moodedness. The indefiniteness of mood, its transient, fleeting character, supports a notion of merging with respect to the phenomenon of co-attunement, i.e. the sharing of the mooded exposure to world. The bodily rooted nature of all moodedness, i.e. of all affectedness by the world, implies also that the union of souls in love or friendship can be described suggestively in a poetic language as 'one soul in two bodies' or 'two hearts beating as one'.He announced his new book today: Social Ontology.
