This entire globe, this star, not being subject to death, and dissolution and annihilation being impossible anywhere in Nature, from time to time renews itself by changing and altering all its parts. There is no absolute up or down, as Aristotle taught; no absolute position in space; but the position of a body is relative to that of other bodies. Everywhere there is incessant relative change in position throughout the universe, and the observer is always at the centre of things.

To remove these one had to account for an “observer” (that is at least for one subject):
(i) Observations are not absolute but relative to an observer’s point of view (i.e., his coordinate system: Einstein);
(ii) Observations affect the observed so as to obliterate the observer’s hope for prediction (i.e., his uncertainty is absolute: Heisenberg).
After this, we are now in the possession of the truism that a description (of the universe) implies one who describes it (observes it).

 

Heinz von Foerster

 

Take movement for example. Forces acting up, down, or from side to side. You make theories to explain it all, but you might well remember that it was you that invented them all. For Mach there was no reason to believe the rest of the cosmos was doing what your little bit was doing, so science should only describe not try to explain. Even description is relative. Am I moving or is the back ground? Or take the position of a star. It depends on the position you see it from, which depends on the date and time, which in turn depends on the position of the earth, in a solar orbit, in a solar system, moving around the edge of a Galaxy which may be moving away from other Galaxies. Say that you've decided that I'm moving and the background is standing still. Is the background moving relative to something else?

 

James (science historian) Burke

 

A modern theory of knowledge which takes account of the relational as distinct from the merely relative character of all historical knowledge must start with the assumption that there are spheres of thought in which it is impossible to conceive of absolute truth existing independently of the values and position of the subject and unrelated to the social context.

 

Karl Mannheim

 

The whole of Bruno's philosophy is based on his view of an infinite universe with an infinity of worlds. He conceived the universe as a vast interrelationship throughout space and time, comprehending all phenomena, material and spiritual. Thence he was led to contemplate the parts under the mode of relativity. The conception of the infinity of the universe renders meaningless the ascription to it of motion, but Bruno conceives each of the infinitely numerous worlds to be moving on its course in relation to other worlds, impelled by its own twofold nature as individual and as part of the whole. All estimates of direction, position and weight within the whole must be relative. Moreover, the cosmological system is illumined by the properties of number.

 

Giordano Bruno

 

When we come to inanimate elements, the prevailing view has been that time and sequential change are entirely foreign to their nature. According to this view they do not have careers; they simply change their relations is space. We have only to think of the classic conception of atoms. The Newtonian atom, for example, moved and was moved, thus changing its position in space, but it was unchangeable in its own being. ...In itself it was like a God, the same yesterday, today, and forever.
