Quote:
There are three ways in which signs can be studied, first as to the general conditions of their having any meaning, which is the Grammatica Speculativa of Duns Scotus, second as to the condions of their truth, which is logic, and thirdly, as to the conditions of their transferring their meaning to other signs.
