If there IS philosophical progress, is it worthwhile to read philosophy that was written before you were born? Isn't the most current understanding of philosophy the most valid? For example, we now know Newtonian physics is false at the quantum level; wouldn't it stand to reason that after two hundred years Kant's moral philosophy has been refined or superceded and should not be followed in its entirety?
If there is NOT any philosophical progress and philosophical questions are inherently unresolvable, then is the entire field of philosophy futile? If philosophers can't even agree on what the aims of philosophy are, then does that mean Marx's philosophy is as equally valid for people to follow as that of Aristotle's?
