Note 228 — LECTURE X
Reading edition
Surely the usual interpretation of 'We fail?' as a question of contemptuous astonishment, is right. 'We fail!' gives practically the same sense, but alters the punctuation of the first two Folios. In either case, 'But,' I think, means 'Only.' On the other hand the proposal to read 'We fail.' with a full stop, as expressive of sublime acceptance of the possibility, seems to me, however attractive at first sight, quite out of harmony with Lady Macbeth's mood throughout these scenes.
