title: Two uneliminated uses for "concepts": hybrids and guides for inquiry.
abstract: Machery's case against hybrids rests on a principle that is too strong, even by his own lights. And there are likely important generalizations to be made about hybrids, if they do exist. Moreover, even if there were no important generalizations about concepts themselves, the term picks out an important class of entities and should be retained to help guide inquiry.
