I did a search for the is/ought problem in this forum but could not find one…
What is the Is-Ought problem? It is usually stated as the problem of whether it is possible to derive normative statements from descriptive statements; but to state the problem at its most general level, it is the problem of whether any moral statement can be literally true, and hence potentially knowable. It is the problem of whether there exist any moral facts in exactly the same sense as there exist chemical facts, historical facts, or mathematical facts.
Firstly, what is the reason why one should sustain one’s life. It is a matter of ‘ought.’ To say that you ‘must’ sustain your life implies a deontological imperative, one that destroys free will. Secondly, what is the rationality of keeping or abandoning reason, is it rational or _ir_rational?
With Objectivist ethics, where moral facts are apparently objective, the following syllogism is defective. It is one that represents the most basic moral reasoning of the Randian system:
The adoption of value system x is necessary for the survival of any human being.
You are a human being.
Therefore, you should adopt value system x.
The missing premise-a prescriptive premise-is that one ought to do what is necessary in order to survive. But any inclusion of that prescriptive premise just triggers the infinite regression of the is/ought dichotomy. Treatment of the problem as a hypothetical imperative would prove equally unsatisfactory:
If you wish to survive, you ought to adopt value system x.
You wish to survive.
Therefore, you ought to adopt value system x.
This syllogism is perfectly valid, but it will not serve for Rand’s purposes, for its introductory conditional makes the entire ethical system subjectively dependent on the individual human will: If you do not choose to survive, there appear to he no grounds upon which the Randians can condemn your judgment morally.
Objectivist ethics are, therefore, thoroughly subjective.
Congratulations: you’ve shown that you don’t understand the Objectivist Ethics.
Please read Tara Smith’s book Viable Values: A Study of Life as the Root and Reward of Morality, particularly the pages on induction and the choice to live (pp. 101-103).
The role of induction is substantial in Rand’s argument for rational egoism. Please take the time to consider it, before regarding the argument as a deduction which falters as soon as someone chooses not to live.
To give some evidence that you don’t understand the argument:
You say that the introductory conditional (the choice to live or not) makes the ethical system “subjective,” which I take to be synonymous with “arbitrary.”
But reality is the grounds on which we decide what is rational or arbitrary, and so the choice to live underlies the very need to be rational–which means that the choice to live or not is a pre-rational choice. Rationality only deals with reality, and if you choose to stay in reality, then reason can be your guide in order to live well.
Also, the objectivity of values stems in part from their beneficial effects on our lives, and also important, it stems from our method (logic) of determining why something is a value (Viable Values, pp. 120-121, note #30 and 34). The objectivity of the values I have do not become subjective simply because another man chose to kill himself. His death does not change the facts regarding various things’ negative and positive effects on my life, nor does it effect the harmful consequences of engaging in the wrong mental process to determine what is valuable to me.
Lastly, notice how your view of ethics is no different from Duty Ethics or commandments: ethics becomes “subjective” to you because it depends on human will and choice. But for Rand (Objectivism), this is simply the recognition of the importance of free will. Morality and Ethics depends on free will, in Rand’s view. We only need ethics and morality because our consciousness is fallible and conceptual; we do not possess the automatic functions and advantageous body parts (e.g. horns) that other animals do have and use to survive; we can, through evasive mental processes or through sheer ignorance, take actions which are detrimental to our lives, and we can even destroy our lives. But through an act of choice, we can engage in correct processes and thereby advance our lives. But there are so many concrete instances of actions needed to live well, and we are not omniscient regarding what the consequences will be of the actions we take now. The solution, in Objectivism, is to conceptualize the requirements for human survival into principles, i.e. into a code of morality.
But if ethics must be independent of human will, as you’ve suggested, then Rand’s Question (in Ethics) becomes crucial to answer: Why does man need Ethics (a code of values)?–Does man need values at all–and why?
If ethics is supposed to be something handed down to man on high, independent of his will, his goals, his interests, then why does not he need to follow it? I’d like to see your answer, though I must warn you that no one has ever proven the validity of “Intrinsicist (Duty) Ethics.”
