Good thinking... almost the same is said by a neo-Wittgensteinian philosopher/anthropolist called Peter Winch, in the article "Understanding a Primitive Society" (I believe this article is also published in MAN 1967 or something?)

P. Winch says that when we want to study an object the researcher has to place the object in the context of the object in order to understand it... so the researcher has to participate to the culture or at least be able to see the whole picture before and during interpretation.
