By the informed depth of a term, I mean all the real characters (in contradistinction to mere names) which can be predicated of it (with logical truth, on the whole) in a supposed state of information, no character being counted twice over knowingly in the supposed state of information. The depth, like the breadth, may be certain or doubtful, actual or potential, and there is a comprehensive distinctness corresponding to extensive distinctness.

By the informed depth of a term I mean all the real characters in contradistinction to mere synonimous names which can be predicated of it with logical truth in the supposed state of information no character being counted twice over knowingly. The depth like the breadth will be certainly doubtful…

The logical compound of all the predicates which can be universally and affirmatively predicated of a term, over and above those implied in its meaning, constitute, when regarded as a quantity, the informed depth of that term, in the state of knowledge referred to.
