Quote from ‘Letters to Paul Carus’
Now we can regard the Interpretant in 3 ways, or rather there are 3 distinct things which may properly be regarded as the Interpretant. For any thing that the sign, as such, effects may be considered as the Interpretant. And this may be 1st something merely subjective, the vague determination of the consciousness effected by the sign, 2ndthe actual event that some signs by virtue of really acting as such bring about. For instance, let the sign be a military word or command. Then the instant action of the whole rank of men will be the Dynamical Interpretant, as I call it.
