Philosophical considerations have been essentially involved in the origin and development of the steady-state cosmological theory. These considerations include an explicit uniformitarian methodology and implicit metaphysical views concerning the status of natural laws in a changing universe. I shall examine the foundations of SST by reconstructing its early history. Whereas the strong uniformitarian methodology of SST found no support in the subsequent development of cosmology, the idea of a possible influence the global structure of the universe may have on the (...) laws of physics operative in it has been assimilated by the standard big bang theory as it made its remarkable progress in recent decades.
