It is vain for the most sanguine meteorologist to wave his arms about and cry: “Monday is past; Mondays will return no more; Tuesday and Wednesday are ours; you cannot put back the clock.” I am perfectly entitled to answer that the changing face of the clock does not alter the recorded facts of the barometer.

Note that this accentuates the relevance of a detail that might be skipped over in the original quote- that Thursday comes after Wednesday. That is, this may be intended as a dismissal of the 'all change is progress' position or the 'traditions are bad because they are traditions' position.
