There is no adequate definition of localization, so far as what emerges into analytic consciousness. The principle of relativity leads us to hold that, with adequate conscious analysis, such local relationships leave their faint impress in experience. But in general such detailed analysis is far beyond the capacity of human consciousness.
So far as concerns the causal efficacy of the world external to the human body, there is the most insistent perception of a circumambient efficacious world of beings. But exact discrimination of thing from thing, and of position from position, is extremely vague, almost negligible. The definite discrimination, which in fact we do make, arises almost wholly by reason of symbolic reference from presentational immediacy. The case is different in respect to the human body. There is still vagueness in comparison with the accurate definition of immediate presentation; although the locality of various bodily organs which are efficacious in the regulation of the sense-data, and of the feelings, are fairly well-defined in the
