Relativity or Relativism?

At the beginning of the 1920s the belief began to circulate, for the first time at a popular level, that there were no longer any absolutes, of time and space, of good and evil, of knowledge, above all, of value. Mistakenly, but perhaps inevitably, relativity became confused with relativism. No one was more distressed than Einstein by this public misapprehension. He was bewildered by the relentless publicity and error which his work seemed to promote.
