At the turn of the twentieth century, when highbrow political thinkers rebelled against the consensual epistemology and ethics of the Victorians, when they argued, as William James did, that “neither the whole of truth nor the whole of good is revealed to any single observer,” when they declared themselves to be living in “a world where truth and justice are to be carved from culture rather than found already etched in reason,” they created an unprecedented problem in liberal political and legal thought. Previous thinkers could take the individual as the fundamental political unit and attribute to “him” a capacity for knowing and doing right that “he” shared with all God's children (as “commonsense” moral philosophy held) or all participants in a consensual, organically developing society (as historicist scholarship had it). Armed with such premises, they could confidently judge diverse social practices against universal standards of conduct.
