 Rand’s naturalism, and her rejection of intrinsicism and subjectivism in favor of objectivism, anticipate recent naturalisms and echo Aristotle’s argument, against both the Platonist and the subjectivist, that “the good” must always be good-for-something. Her conception of the function of morality is notable both for its affinity to, and its difference from, Thomas Hobbes’ conception: like Hobbes, Rand sees morality as a necessary means to long-term survival, but unlike Hobbes, she does not see morality as requiring a contract or even as a fundamentally social affair. The need for morality, according to Rand, is dictated by our nature as creatures that must think and produce to survive; hence we would need morality even on a desert island. There is, however, no duty to survive; morality is based on a hypothetical imperative: if you choose to live, then you must value your own long-term survival as an ultimate end, and morality as a necessary means to it. If asked why the choice to live commits you to your own long-term survival rather than some other ultimate end (such as, for example, the greatest happiness of the greatest number (Nozick 1971), or becoming worthy of eternal life in heaven), the only answer is: because any other ultimate end, if consistently adhered to, would lead to death.
