In this short paper we briefly discuss the issue of the theory of general relativity as a supposed generalization of the theory of special relativity to see if general relativity did really generalize special relativity as a relativity theory. The simple conclusion that we reach in this discussion is that the theory of general relativity is not actually a generalization of the theory of special relativity and hence general relativity is neither a general theory nor a relativity theory. In short, the so-called "general theory of relativity" should more appropriately be called the "special theory of general covariance" since it is special in content (as it is essentially a gravitation theory) and it lacks the physical substance of relativity (as it is actually about mathematical artwork of general covariance rather than about physical relativity).
