I distinguish three primary notions of objectivity that may be applied to the sciences. There is an ontological sense of objectivity which relates to the way in which the natural world exists independently of human thought. There is a semantic form of objectivity which relates to the nature of truth. There is an epistemic notion of objectivity which relates to the methodological norms and procedures which are employed in the sciences, and the epistemic justification of beliefs and theories which are (...) licensed by those norms and procedures. These three forms of objectivity may be brought into conjunction. It is because we employ methods of scientific inquiry which function to exclude subjective factors and to incorporate only genuinely epistemic factors that the results and theories of the sciences should be accepted. They should be accepted because by employing such methods we have the best chance of arriving at true beliefs about the nature of reality. In short, it is the epistemic objectivity of the methods of science that leads us to the objective truth about the objective world. (shrink)
