Mark.

It is the mark of an educated mind to expect that amount of exactness in each kind which the nature of the particular subject admits. For it is similar to expect a mathematician to speak persuasively or for an orator to furnish clear proofs!

Each person judges well what they know and is thus a good critic of those things. For each thing in specific, someone must be educated to be a critic; to be a critic in general, one must be educated about everything.
