What is philosophical genealogy? What is its purpose? How does genealogy achieve this purpose? These are the three essential questions to ask when thinking about philosophical genealogy. Although there has been an upswell of articles in the secondary literature exploring these questions in the last decade or two, the answers provided are unsatisfactory. Why do replies to these questions leave scholars wanting? Why is the question, “What is philosophical genealogy?” still being asked? There are two broad reasons, I think. First, (...) on the substantive side, the problem is that genealogical models will get certain features of the method right but ignore others. The models proffered to answer the first question are too restrictive. The second reason is that the three essential questions to ask regarding the nature of genealogy are run together when they should be treated separately. In the following paper, I address these problems by attempting to reconstruct genealogy from the ground up. I provide what I hope is an ecumenical position on genealogy that will accommodate a wide variety of genealogical thinkers, from Hobbes to Nietzsche, rather than a select few. Therefore, I examine two of the three questions above: What is philosophical genealogy and its purpose? I argue there are seven main features of genealogy and that these features may be used as a yardstick to compare how one genealogist stacks up to another along the seven aspects I outline in the paper.
