Here is a thoughtful sentence on the aim of a classical Christian education by David Hicks. I would change only a few words in it (if you have yet to read his Norms and Nobility you should--it is really excellent):
The Aim of Classical Education
The formation of a mature person who loves inquiry that reaches into earthly as well as transcendent realms of knowledge, who makes the connection between this knowledge and his responsibility in the life of virtue, and who struggles against long odds to fulfill in himself the high exigencies of the Ideal Type. (David V. Hicks, Norms & Nobility)
