There is a dialectics at work in every philosophical intuition. This is apparent in Husserl’s twofold definition of “sensible” and “categorial” intuition, as much as in Bergson’s intuition of “duration,” where thought is forced to reflect back on itself in the very act of grasping its object. The formal aspect of this reflective process produces ambivalence. It breaks with the ideal of immediacy and coincidence that still governs the metaphor of intuition as a vision from within (intuition as “sympathy”). This is confirmed by the dynamics of cosmological intuition: an intuition that strives to embrace the simultaneous unfolding of the whole universe, i.e. the parallel flows of multiple and possibly distant and dispersed durations. The famous Bergsonian example of sugar and water plays a prototypical role here. But uncovering the wider temporal meaning of coexistence and simultaneity requires a special effort to reach beyond the proximal zone of co-presence. It involves a form of split-attention aiming at the absent as such—the concealed now-there. A confrontation between Merleau-Ponty, Sartre and Bergson on this issue brings out new facets of the dialectics of intuition.
