 What are properly inferences from our observations come by processes of association to seem as observations themselves. I observe, properly, only a certain sensory manifold, and infer that this is my brother—but, with repetition, the inference becomes merged by association with the observation, and I take the inferred content to be part of the observation itself. Processes of association, that is to say, renders our observations deeply theory laden. And the theories with which they are laden, of course, will vary with social setting.
