 What about the possibility of acquaintance with ourselves? Can an individual be directly acquainted with him or herself? Russell takes the question of whether we are ever acquainted with the self to be a difficult one. He says that acquaintance with the self is “hard to disentangle from other things,” but tentatively concludes that “it is probable, though not certain, that we have acquaintance with Self” (1912: 78–81.) However, he later denies that we have acquaintance with the self (see Russell 1914: part III). In a recent paper, Duncan (2015) uses the method of doubt, or something very much like it, to argue that we are acquainted with ourselves.
