What do you mean by truth? We act on heuristics that are sufficiently good approximations to be useful. For example, we act as if the world is flat when we run or drive. We act as if the world is spherical when we fly across continents. However, both are only approximations to the reality (Earth is an ellipsoid). We use them because they are useful. It is reasonable to have multiple views of the world that changes with scale.
