  Kant divides these ordering principles into the Forms of Sensible Intuition and the Categories. Space and Time are pre-experiential ordering principles that give us sense experience of a spatial and temporal world. The Categories play a parallel role for the understanding. Through the category of Causality, for example, we impose causal structure on the events that we perceive. This imposed structure allows us to move from the subjectivity of successive sensations to experience of an objective world. Consider an analogy: the pixel structure of every picture that a digital camera takes is the result of an ordering principle imposed on every photograph by the nature of the camera. The pixel structure of the representations does not capture a feature of the camera-independent reality.  Similarly, the spatiotemporality and categorical structure of our experience is not a feature of a mind-independent reality.
