Two Kinds of Empiricism

The scientist starts with sensory concepts, i.e., concepts that are entirely determined by their referents. The referents in turn, can be measured directly using an appropriate experimental apparatus. For example, the concept "frequency of light" would be used to denote the vibrational patterns of light as measured by an appropriate optical device. Sensory concepts are unproblematic as far as the scientist is concerned since they denote facts and as we know, facts are basic. There is nothing more certain in science than facts.
