Just Wondering

This has been bothering me for some time, even though it probably shouldn't. The Bible teaches very clearly that pride was the sin that sent Lucifer from God's presence, pride goes before a fall, and that the Lord opposes the proud, among other verses that teach very strongly against pride. Additionally, if C.S. Lewis was correct in his analysis of pride, calling it "The Great Sin" in an incredibly insightful chapter of Mere Christianity in which he argues that pride is essentially a starting point for all kinds of other sins, then why is humility not listed as one of the fruits of the Spirit? Wouldn't it seem that it should be there and sort of near the top (if they are ordered in any particular manner)? Any thoughts?
