Log in. Course materials. He's just going to have to decide who to shave in some different way." $\begingroup$ Firstly, the Russell paradox is talking about membership ($\in$) not containment ($\subseteq$); every set contains itself (as a subset), so in that sense there is no point in talking about the set of sets that do not contain themselves (which would be the empty set).
