[This request of Augustin to his reader, involves an admirable rule for authorship generally—the desire, namely, that truth be attained, be it through himself or through others. Milton teaches the same, when he says that the author must “study and love learning for itself, not for lucre, or any other end, but the service of God and of truth, and perhaps that lasting fame and perpetuity of praise, which God and good men have consented shall be the reward of those whose published labors advance the good of mankind.”—W.G.T.S.]
