Liberal vs Useful

How does Newman define "Liberal" and "Useful" education? Which of the two does he promote? How and why?

Newman feels there are two different types of knowledge and education, "Liberal" and "Useful". Useful knowledge is more technical and practical. This is the scientific knowledge of creation, and thus especially useful during this age of technological advances. In reference to "useful knowledge", Newman feels that, "Knowledge, in proportion as it tends more and more to be particular, ceases to be Knowledge" Though Newman finds this type of knowledge to be good and of it's own sort of use, but he feels eventually it becomes so specific that it is no longer knowledge. I feel he means that it becomes so specialized that it can only be useful for something in particular and not a knowledge good for discussion and sharing. Liberal knowledge is more philosophical. This education is much more generalized and rounded out. Newman I feel prefers it because this is what he himself shares in. Of this type of knowledge he feels, "...that there is a Knowledge, which is desirable, though nothing come of it, as being of itself a treasure, and a sufficient remuneration of years of labor." Liberal knowledge is something to expand upon and be discussed and furthered. It will never not be knowledge, even if it were to become a book as then it would simply be relayed knowledge.

I get what he's saying, but it seems a little silly. He obviously respected "useful" knowledge, but he finds himself working in liberal knowledge and so favoring it.
