But it is well worth while to try at all costs to get firm hold of the fact that anthropology, though a big thing, is not everything.
It will be enough to insist briefly on the following points: that anthropology is science in whatever way history is science; that it is not philosophy, though it must conform to its needs; and that it is not policy, though it may subserve its designs.
