If possibility is the ground of being, then actuality is not a brute fact but a cut — a perspectival crystallisation within the field of potential.
Traditionally, philosophy has ranked actuality above potential. Aristotle defined potential as incomplete being, striving for the perfection of actuality. Physics tends to imagine the actual as primary — the particle detected, the law obeyed, the measurement recorded — with potential reduced to a cloud of hypothetical states. Theology often cast possibility as subordinate to divine will, a canvas for what God decides to actualise.
But from a relational perspective, this hierarchy is inverted. The actual is always situated, perspectival, contingent. It does not exhaust reality; it opens onto possibility. Every actualisation is a local cut in a larger horizon, a crystallisation of relation that could have unfolded otherwise.
Potential, in this sense, is not lack. It is abundance: the plenitude of relation that makes multiple actualisations possible. Actuality, then, is simply one trajectory through this abundance — one alignment of relation that constrains and shapes what can be.
The interplay between potential and actual is not static but rhythmic. Actualisations feed back into possibility, shifting constraints, redefining horizons, opening new lines of becoming. Cosmos itself is this rhythm — the continual folding of the possible into the actual, and the opening of the actual back into the possible.
To study reality is to study this movement: not just what has become, but the ongoing becoming of possibility itself.
