… This thesis, which comes from a famous passage in Hume’s Treatise, while not as clear as it might be, is at least clear in broad outline: there is a class of statements of fact which is logically distinct from a class of statements of value.No set of statements of fact by themselves entails any statement of value. Then I might actually understand the rest of my essay! Facts can't solve that problem, they simply provide some framework. Those of us who deny that you can derive "ought" from "is" aren't anti-science, we just want to take science seriously, and not bend its definition beyond all recognition. Third: morality is still possible. As we'd put it in modern lingo, it seems that no number of statements using the copula "is" can ever (just as a matter of propositional logic) entail a statement with the copula "ought". More needs to be said about the Sam Harris, in The Moral Landscape: How Science Can Determine Human Values, disagrees. But that's just cheating. It is often said that one cannot derive an ‘ought’ from an ‘is’. If the "ought" is therefore added by us, it must be subjective, and cannot belong intrinsically (part of it's nature) to the action or fact in the world. God’s nature serves to establish values—goodness and badness—while God’s commands establish moral duties—what we ought or ought not to do. But it's a role, not a foundation. That question, prompted by Hume's small paragraph, has become one of the central questions of ethical theory, and Hume is usually assigned the position that such a derivation is impossible. If we can’t find a coherent way to integrate these “is” claims with the rest of our network of reasonable “is” claims, then we can’t argue coherently for such “ought” claims at all. Eric Olson - 2010 - Theoretical Medicine and Bioethics 31 (4):259-270. Ought: We dont know, but just because there is slavery it can not be moral yet. Get 1:1 … The “is-ought fallacy” is another recurring ‘folk philosophy’ phrase – meaning “you can’t derive an ‘ought’ from an ‘is’”, after Hume. Chapter three considers whether it is possible to bypass the IOP by beginning with premises concerning the de facto desires of human agents. Antonio Rauti - 2009 ... -174. Therefore, he ought to do whatever he ought to do. I think this is entirely hopeless; if the inference is valid, I missed the first two or three lessons so I am very confused. However, Searle’s statement is also an ethical one. It's a question that has to be answered through our social mores, ethical systems, etc. Harris admits that "no one expects science to tell us how we ought to think and behave." But how exactly "can" you derive an "ought" from an "is"? This chapter seeks to show that our semi‐Kripkean semantics and other forms of metaethical sentimentalism as well (e.g. The argument is of the form: If C then (if U then P): C for conditions, U for utterance, P for promise. It tells us what to do, that we ought … Yes Or No? Yes or no? All page references in the text are to this article.) In my opinion this statement would make more sense if it means that we can not derive our morals from the situation we handle our moral dilemmas until now. A failure to see the force of socially constructed moral rules leads to the fallacy of deriving an “is” from an “ought,” as if those rules were themselves facts. Can we derive an ought from an is?

IIRC, John Searle once published a paper whose central argument was something like this: The following is valid: I promised to do X Therefore, I ought to do X So one can derive an "ought" from an "is". The problem of course is that, if we can't derive an ought from an is, then Hume cannot say that reason *ought* to be the slave of the passions, merely because she is so in fact (according to him). Sure, you can’t derive an ‘ought’ from an ‘is’, but that doesn’t matter because all our ethical duties originate from our built-in feelings. What is the is/ought distinction? Whether what science offers us is something we ought to value and ought to continue doing, well, that’s not a question science can answer, and we shouldn’t talk in ways (as Harris does) that encourage a conflation of the epistemic performance of science on the one hand with our fundamental desire and motivation for the things science offers, on the other. We can see this demonstrated through the use of logic in a deductive syllogism known as “The Moral Argument.” Here it is: 1- If God does not exist, objective moral values … Continue reading An OUGHT From An IS Therefore, we can say that Searle is correct in that his example is only a factual account. Ethics and the Generous Ontology. How can we derive an ought from that fact? Grounding moral values in God no more derives an “ought” from an “is” than does Plato’s grounding values in the form of the Good (indeed, one of my critiques of moral platonism is precisely its failure to provide any basis for moral duty). The is-ought distinction is sometimes misconstrued to mean that facts are totally disconnected from ethical statements, or that there is no relationship at all between is and ought. Back when I was in college and taking up philosophy, the received opinion concerning ethics claims, the standard doctrine espoused by all my teachers, was that, since Hume at least, we can all agree that one can't derive "ought" statements from "is" statements, that is claims about what we ought to do in any given case do not follow based on the descriptions of the facts of the case alone. Maybe it's perfectly reasonable to hurt humans despite their pain. On my first lesson we got given an essay and the title is 'you cannot derive and ought from an is' Can anyone please explain to me what is meant by this phase? Most think there is a gap between scientific "facts" and moral values. I am a little surprised that this contradiction goes unremarked by the Nortons in their Oxford Philosophical Texts edition of the Treatise. possible validly to derive an ―ought‖ conclusion from ―is‖ premises and asks whether their attempts can be imitated successfully by those who wish to uphold the basic claims of NLT. Is the key issue in getting an ‘ought’ from an ‘is’ whether it involves an imposed will? I’m instead pointing out that most every attempt to derive an “ought” is based ultimately on “is” claims about the reliability of our intuitions about such more basic “ought” claims. This question hasn't been answered yet Ask an expert. Robert V. Hannaford - 1972 - Ethics 82 (2):155-162. Thus it seems that we can derive “ought” from “is.” Hume was wrong, then, to say that we can never derive “ought” from “is.” But he was wrong for a reason that his own analysis exposes. The Is-ought problem is a problem attributed to David Hume which asks how we can derive a normative claim from a descriptive claim.It is highly related to the Fact-Value distinction.. People who believe in the is-ought problem consider deriving normative claims from descriptive claims an informal fallacy.They call it the Is-Ought fallacy and sometimes the Naturalistic fallacy. For a modern proponant of a similar argument, read Simon Blackburn. In this response I shall argue that whether we ought to or not, we do not and can not derive ‘ought’ from ‘is’ and that in the procedure used by Hannaford he does not derive ‘ought’ from ‘is’ but does muddy the water concerning what is … You can also do the job if you redefine "ought" so that it is no longer about having reasons for action, but about actions that conform to a stipulated definition of "good", e.g. If nature does not make it, we shouldn't have it. If everyone could agree on definitions and measurements for human well-being the same way they can about, say, an electron, Harris would be absolutely right that we could derive an “is” from an “ought.” (Conversely, if there was a sizeable school of physicists who disbelieved in the notion of matter-waves, what “is” an electron wouldn’t be so clear as it is for us. However, I think most people who want to say we can derive an ought from an is would all agree with this rather trivial observation. In short, there is nothing on the other side of the is-ought gap. Can We Derive the Principle of Compositionality (If We Deflate Understanding)? So yes, there are various well-known ways to derive "ought" from "is". Kames and Smith held the same view, although they amplified Hume’s account of the moral sentiments and in particular distinguished between the sentiments of benevolence and justice. ‘Ought to be enough sugar’ v ‘OUGHT to do as I say’?
