 In turn, McTaggart was influential in the intellectual development of G.E. Moore. McTaggart was Moore’s youngest philosophy teacher at Cambridge. According to Paul Levy what influenced Moore most was McTaggart’s “constant insistence on clearness, on asking the question ‘what does this mean’” (Levy 1981, 60). Moore read and commented on early drafts of both McTaggart’s Some Dogmas of Religion, published first in 1906, and the first volume of the Nature of  Existence.[5]
