  One scholarly debate about cohesion concerns the question of whether Locke acknowledged only the limited problem, as one would expect from commentators who read him as accepting atomism (e.g. Mandelbaum 1964, p. 1), or whether he looked further, to the more serious, foundational problem, as Hill argues (2004). A related controversy, to be discussed in the next section, concerns the questions of whether Locke concludes that the corpuscular hypothesis simply cannot resolve the problem (e.g., Hill 2004; Downing 2007, p. 408), or whether he remains agnostic on the issue (e.g., McCann in Chappell 1998, p. 244).
