The second edition appeared in 1827. Since the autumn of 1818 Hegel had been professor at Berlin: and the manuscript was sent thence (from August 1826 onwards) to Heidelberg, where Daub, his friend--himself a master in philosophical theology--attended to the revision of the proofs. 'To the Introduction,' writes Hegel[9], 'I have given perhaps too great an amplitude: but it, above all, would have cost me time and trouble to bring within narrower compass. Tied down and distracted by lectures, and sometimes here in Berlin by other things too, I have--without a general survey--allowed myself so large a swing that the work has grown upon me, and there was a danger of its turning into a book. I have gone through it several times. The treatment of the attitudes (of thought) which I have distinguished in it was to meet an interest of the day. The rest I have sought to make more definite, and so far as may be clearer; but the main fault is not mended--to do which would require me to limit the detail more, and on the other hand make the whole more surveyable, so that the contents should better answer the title of an Encyclopaedia.' Again, in Dec. 1826, he writes[10]: 'In the Naturphilosophie I have made essential changes, but could not help here and there going too far into a detail which is hardly in keeping with the tone of the whole. The second half of the Geistesphilosophie I shall have to modify entirely.' In May 1827, Hegel offers his explanation of delay in the preface, which, like the concluding paragraphs, touches largely on contemporary theology. By August of that year the book was finished, and Hegel off to Paris for a holiday.
