everything already always is. the potential movement or changes possible for a concept/phenomena must be themselves contained within the concept/phenomena. the oak tree is not a completely separate phenomena from the acorn, but rather a specific stage of the entire being of the tree-seed dichotomy/spectrum, the possibility for the tree already exists/is already contained within the acorn. yet the tree will not grow without the appropriate set and setting (soil, light, water, gravity, atmosphere, etc.), so these too must all be considered as a unified whole in some sense along with the tree-seed.
