No, just that.

But is knowledge or want of knowledge of health the same as knowledge or
want of knowledge of justice?

Certainly not.

The one is medicine, and the other is politics; whereas that of which we
are speaking is knowledge pure and simple.

Very true.

And if a man knows only, and has only knowledge of knowledge, and has no
further knowledge of health and justice, the probability is that he will
only know that he knows something, and has a certain knowledge, whether
concerning himself or other men.

True.

Then how will this knowledge or science teach him to know what he knows?
Say that he knows health;--not wisdom or temperance, but the art of
medicine has taught it to him;--and he has learned harmony from the art of
music, and building from the art of building,--neither, from wisdom or
temperance: and the same of other things.

That is evident.

How will wisdom, regarded only as a knowledge of knowledge or science of
science, ever teach him that he knows health, or that he knows building?
