Full Idea
Whoever is afraid of symbols can hardly hope to acquire exact ideas where it is necessary to distinguish 1) the variable in itself as opposed to its value, 2) any value of the variable, 3) all values, 4) some value.
Gist of Idea
We can't sharply distinguish variables, domains and values, if symbols frighten us

Not the best example, perhaps, of the need for precision, but a nice illustration of the new attitude Russell brought into philosophy.
