Not all of us who believe physics-since-1600 and biology-since-1860 have seen unequivocal progress believe there has been unequivocal progress in popular political or moral opinion. The civil-rights movement of the 1950s and 1960s for example clearly represents an increase in the consistency of the application of the ideal of equality, but it constitutes unequivocal progress only if you believe that the spread of the ideal of equality constitutes unequivocal progress.
I have not noticed that, Ben.
