Can we say that s knows whether A or B when s is only able to rule out A, but remains uncertain about B? We discuss a set of examples put forward by J. Schaffer’s in favour of a contextualist answer to this problem. We present a context-sensitive and dynamic semantics for knowledge attributions, in which those can depend on the alternatives raised by the embedded question, but also on alternati...
Excitable cells rely on selective ionic conductances for electrical signaling. The work of Hodgkin and Huxley (1) propelled the modern dissection of the mechanisms of selectivity. Their formulation postulated two independent sets of ionic conductances, Na and K, whose relative permeabilities changed during the course of excitation. Mullins subsequently proposed that Na and K traverse the membra...
