states of a medium, and are not bound down to any bearer, but they are independent realities which are not reducible to anything else, exactly like the atoms of ponderable matter. This is how Einstein added to the metaphysical parts of the theory. He added the concept of a field as being an independent part of nature. He also removed the concept of the ther. The fact that Einstein was concerned with the values that a paradigm holds can be seen in how much Einstein let epistemological considerations influence his thoughts. The paradigm that Einstein created must also provide certain things. These were listed above, and include things like defining the basic terms. Because revolutionary science is inherently arational, Einstein defended his changes in definitions of the basic terms as such:With what right - the reader will ask - does this man operate so carelessly and primitively with ideas in such a problematic realm without making even the least effort to prove anything? My defense: all out thinking is of this nature of free play with concepts; the justification for this play lies in the degree of comprehension of our sensations that we are able to achieve with its aid. The concept of truth can not yet be applied to such a structure; to my thinking this concept becomes applicable only when a far-reaching agreement (convention) concerning the elements and rules of the game is already at hand. This shows how Einstein was aware that his was changing the definitions of words. Einstein shows how he is redefining time like this: That my definition satisfies this demand is indisputable that light requires the same time to traverse the path A -* M as for the path B -* M is in reality neither a supposition nor a hypothesis about the physical nature of light, but a stipulation which I can make of my own freewill in order to arrive at a definition of simultaneity It has been assumed that all these clocks go at the same rate if they are of identica...
