If you want to use a different translation you are welcome to, but you should be aware that it may be confusing because translations can differ greatly. Of course, if you know German, you should read in the original.
We will be reading exclusively the text of the second (“B”) edition. Page numbers in both the first and second (“A”) editions are marked in the margin of Smith’s translation. In most cases where the two editions differ, it should be relatively easy to figure out what the text of the B edition says: Smith mostly either prints the B-edition text with A-edition difference in footnotes, or, where there are big differences, prints the two texts separately.
