Constancy
The act of knowing always takes place in a non-empty space. Every search for knowledge tries to discover a stable pattern — in examining a pre-existing structure. Even the pattern itself is in a sense already existing.
Nevertheless something is created: exposing the new means changing the existent. The pattern becomes a thing that has not been so before. It solidifies, becomes concrete, graspable. So that something new arises being more than simply a new arrangement. The crux is its creation which does not happen once and for all, but ever anew, whenever the new thing appears. The fact that this happens habitually or automatically does not mean that no activity is needed.
