While reading Human Action I realized that even Mises speaks from a Kantian premise. However he succeeds in anchoring a rational plane of thought which even the Kantians must accept if they have to achieve the ends they seek. He seems to have united all men with the same system. Unfortunately since he does not make value judgements, men under his system might wrongly blame the system instead of blaming the ends they sought to achieve. Here is where Ayn Rand differs. She prescribes both the premises and ends for men unlike Mises who let men to choose whatever premise or end Rey wish.
