Heraclitean ground of the coniunctio

The philosophical root of the coniunctio is Heraclitean. The claim that opposites form a unity through productive tension — rather than resolution, cancellation, or synthesis — is first stated in the fragments. “The divine logos expresses itself always in opposites… though absolutely different, they none the less possess a unity” (Sullivan 1995). The figure is the bow and the lyre: “being at variance it agrees with itself: there is a back-stretched connection (harmonie) as in the bow and the lyre” (Heraclitus B 51, quoted Sullivan 1995). The stick and the string are irreducibly different; together they hold a tension that is the condition for a world. Heraclitus pushes the claim further in B 80: “justice (dike) is strife (eris), and… all things come into being according to strife” (quoted Sullivan 1995). Justice is not the abolition of conflict but its right measure.

This is the seed of what alchemy names the coniunctio and what Jung names the transcendent-function. The opposites must first be distinguished (a separatio) before they can be joined; the joining is never the end of their difference but the attunement that lets the difference produce a third thing. Jung’s paradox “opposition and identity at once — a philosophical problem only when taken as a psychological one!” (Jung 1954, CW 16, §455) is a direct Heraclitean inheritance. The graph records the continuity: the harmonie of the bow is the archaic form of the coniunctio oppositorum.
