Dr. Shirley intended, as general Editor, to have prefixed to the works an elaborate Introduction, in which he would have endeavoured to fix the exact theological position of the writer in reference both to his own and to later times, besides probably settling, so far as the means at our disposal allow, the chronology and authenticity of the immense mass of writings ascribed to Wyclif,a subject which Bale left in utter confusion, and which Lewis has done very little to elucidate. Such minor matters as the critical collation of MSS., the preparation of a text for the press based on such collation, the verification of references, and the illustration of the text by occasional notes, he desired to commit to the hands of an assistant or assistants; and it was thus that he asked me to take a share in the work. I gladly consented,having indeed already formed the opinion independently, after reading the Fasciculi Zizaniorum and Dr. Shirley's admirable Introduction to that strange miscellany,that the principal works of the reformer, particularly his English works, ought long ere this to have been given to the public. Before, however, any material step had been taken towards the execution of his plans, this good man and ripe scholar was cut off by death. A greater share of the responsibility of the edition has, in consequence, been thrown upon me than was originally intended, or than, to say the truth, I feel myself quite competent to meet. I have however spared no pains to give to the reader a faithful and readable copy of those of the original works, which it has been resolved to print, and for this purpose I have collated, in whole or in part, a number of other MSS., preserved in various libraries, with the excellent Bodleian Codex, upon which the text of the following Sermons is based. I have also entered in the following pages, and shall enter more at length in the Introduction to the third volume, on the critical questions relating to the authenticity of the various works ascribed to Wyclif, so far as the discussion is necessary in order to justify the selection of his writings which has been made.
