  The idea of a hierarchy of modes is not particular to Idealism. Where there are different understandings, someone interested in reconciling them might argue that they represent different levels of understanding, some more inclusive and in that sense higher than others. In contrast to unifying philosophies, including philosophical Idealism, Oakeshott’s position is pluralist and anti-hierarchical. In this respect he has more in common with Wilhelm Dilthey, who struggled with the issue of relativity in metaphysics and how to distinguish the human from the natural sciences, than with the British Idealists—Bradley, Bosanquet, and McTaggart among others—with whom he is often associated (Boucher 2012). For Oakeshott, all knowledge is conditional. Theorizing is “an engagement of arrivals and departures” in which “the notion of an unconditional or definitive understanding may hover in the background, but … has no part in the adventure” (OHC 2–3). In attempting to construct a coherent view of the world the philosopher “puts out to sea” (OHC 40) and is perpetually en voyage: there are no “final solutions” in philosophy any more than in practical affairs.
