 Objectivity, according to the Marburg view, depends on laws. For example, a particular physical thing (say a table in a room) appears in a certain way from my own subjective point of view in the room. To achieve an objective representation of the table, I would need to understand how all of the various appearances at various points of view in the room are related to one another in a law-like way. When I know the law, I’ve moved from appearance to reality, from subjectivity to objectivity. If there is no such law, then there is only appearance, and I cannot speak about an independent object and its properties. This simple point generalizes at higher levels. It merely appears from our subjective point of view that the earth is stationary and the sun moves. But it is objectively the case that the earth moves around the sun because the heliocentric model follows from Newton’s laws of motion. Even more fundamentally, scientific theories (such as Newton’s) are developed, adopted, and abandoned as science progresses; this whole progression is itself objective because there are “laws” (that is, a common scientific method) that prescribe these changes. These laws secure the “unity” of knowledge: the various appearances of the same particular are united as of the same particular object by a law; a law of nature unites various observed phenomena under it; the scientific method unites science in its development, prescribing a uniquely correct path to follow. This unity can also be described as “permanence”: the appearances change, even as the object stays the same; the planets move, but the law remains; theories come and go, but the method stays constant. This notion of objectivity as lawfulness is then used to give an account of truth and objecthood. Knowledge is true if it can be unified with other knowledge within an objective system of knowledge. Last, an object is then what is known by fully objective knowledge:
