How philosophy makes progress.   Philosophy isn’t literature, and it is isn’t failed or primitive science. Instead, according to Rebecca Newberger Goldstein, its task is to make our points of view increasingly coherent. “It’s in terms of our increased coherence that the measure of progress has to be taken, not in terms suitable for evaluating science or literature. We lead conceptually compartmentalized lives, our points of view balkanized so that we can live happily with our internal tensions and contradictions, many of the borders fortified by unexamined presumptions. It’s the job of philosophy to undermine that happiness, and it’s been at it ever since the Athenians showed their gratitude to Socrates for services rendered by offering him a cupful of hemlock.”
