In this paper, I present, first, a syncretistic account of existence, which tries to show not only that the first-order and the second-order notions of existence are compatible, but also why we need all of them in order to properly understand what existence all in all amounts to. Second, I discuss to what extent Marty's account of existence, which inter alia mobilizes Brentano's attitudinal approach to it, can be legitimately considered to be a syncretistic account as well.
