Hi,
"While it is unlikely that Mr. Rumsfeld would describe himself as a postmodernist, he does seem to
be invested in the obscurity of truth and the indeterminacy of meaning, and to believe that what we know is constructed by language rather than reflected in it."
How should I understand the phrase "be invested in" in this context?
I've looked through the list of definitions at Oxford online dictionary and none of them seems to fit precisely:
