  Many of Heidegger's translators capitalize the word ‘Being’ (Sein) to mark what, in the Basic Problems of Phenomenology, Heidegger will later call the ontological difference, the crucial distinction between Being and beings (entities). The question of the meaning of Being is concerned with what it is that makes beings intelligible as beings, and whatever that factor (Being) is, it is seemingly not itself simply another being among beings. Unfortunately the capitalization of ‘Being’ also has the disadvantage of suggesting that Being is, as Sheehan (2001) puts it, an ethereal metaphysical something that lies beyond entities, what he calls ‘Big Being’. But to think of Being in this way would be to commit the very mistake that the capitalization is supposed to help us avoid. For while Being is always the Being of some entity, Being is not itself some kind of higher-order being waiting to be discovered. As long as we remain alert to this worry, we can follow the otherwise helpful path of capitalization.
