The previous reviewer was spot on, this is the gold standard when discussing representation. I cannot add much to the previous review in terms of praise. I mean the other reviewer is on, but what I can do is add substance. Pitkin offers four views of representation. They are the formalisitic, which stresses authorization and accountablitly; symbolic, which stresses a representative has some meaning to those that they are trying to represent; descriptive, which highlights the degree to which the representative matches the characteristics of those being represented; and substantive, which highlights what the representative does for those they claim to represent. This is a book of theory and each of these is detailed in a very understandable way, which makes this book of theory seem less like a tome you would want to avoid. Overall, a good book.
