'As long as life lasted, work could be revised. To facilitate that process, for instance, Mill left as an open question in the seventh edition of the Principles of Political Economy the issue of a wages fund (4:xxxix), an issue he ultimately found no opportunity to clarify. Mill even entertained the bizarre idea of developing a system of "marks" for the "alterations and additions" that such revision entails, a kind of typographical equivalent to Faulkner's fanciful notion about using different colors of ink to mark the temporal shifts in The Sound and the Fury. With regret, however, Mill gave up such a scheme: "one could scarcely give distinctive marks to all the successive strata of new matter" (16:1108). One's past thought is like a cross section of still malleable geologic matter: it offers evidence of the changes that have already occurred, but remains open to further evolution.'
