Joyce is not easy, cooliegirly; I hope you know what you’re getting yourself into.

Your quote is the idealistic hope of the young writer, and is expressed with a rather naive valour:

to forge in the sanity of soul the uncreated conscience of race = to write (forge = make), through his own genius (sanity of the soul), the definitive expression of (Celtic Irish) humanity (the uncreated conscience of race).

I think you have a misprint/mistranslation, however. My edition reads:

…to forge in the smithy of my soul the uncreated conscious of my race.
