I suppose since my comment started this thread I should respond. I’m not sure “absolutism” is the right term for my position, but I would accept the legal concept (which is frequently misused) of “natural law,” that some things are always wrong, regardless of circumstances.
I am not asserting any moral high ground here, as I freely admit I am as prone to committing wrong (I propose we not use the term “sin” as that would introduce religious elements not necessary here) as the next person. But I do believe that lying is always, always wrong. That does NOT mean that under circumstances I would not find it reasonable or necessary for a person to choose to commit that wrong, but you still have to accept whatever the consequences of that wrong, and you should not try to pass it off as not being a wrong.
I do believe “white lies” such as lying if your boss asks if his wife is fat, or if your wife asks if those pants make her derriere look fat, are wrong. I do not find it reasonable or necessary to tell a lie in those circumstances. What I do recommend, and can find Biblical justification for, is the telling of an alternative truth.
In 1 Samuel 16, we are told God told Samuel to go anoint David as the successor king to Saul. Samuel tells God if he does that, Saul will kill Samuel. God tells Samuel to take a sacrifice along so he can say he is making the trip to make the sacrifice, and thus not have to say he is going to anoint David. Here, in response to a situation where the truth could result in death, the Bible suggests telling, not a lie, but an alternative truth.
Islam, Judaism, Druze and Sabianism have the concept of “taqiyya,” which authorizes lying upon compulsion of death.
If, as a hypothetical example, an armed criminal broke into my house, subdued me, and then asked me if my children were home, I would not have a problem with lying. I believe the lying would still be wrong, and I would be responsible for the consequences of that wrong, but I would find it reasonable and necessary to accept that under those circumstances.
I believe killing another human being is always wrong. Under some circumstances, while not pretending it is right, I do believe it may be reasonable and necessary. As an example, if that same armed criminal was threatening my life or that of any innocent person, I do not have a problem with killing the criminal to prevent another wrong. It is still wrong, but reasonable and necessary.
Do not confuse the legal concept of “justification” for the concept of “right.” If your wrong was justified, it means you will not have to suffer consequences for the wrong, it does not mean the wrong was right.
Lying to gain a business advantage, or to entice someone to do business with you when you know if you told the truth they would not do business with you at all or not on the terms you prefer, is always wrong. You deprive the other party of the ability to act with a full understanding. Even if the other party is a big evil corporation.
To answer another question above, I am not a Catholic. If you have a difference with the practices of any group to which you associate yourself, I believe you have an obligation to act honestly and refrain from the prohibited conduct while you work peacefully to persuade the group of your position. If you are not able to do so, I believe the honorable option is to either choose to forego that conduct while you associate yourself with that group, find another group, or start your own. I disapprove of continuing to represent yourself as part of that group while you act contrary to the group’s practice, even if you believe the group is wrong, even if the group is wrong. That is hypocrisy.
I think we blur the moral issues when we use terms like “OK to lie.” It should not be thought to be OK or right to, as in the example, prevent ethnic cleansing by lying, but it should be acknowledged as justified. Otherwise, you dilute the concepts of “right” and “wrong.” When it comes to something this important, I believe it is crucial to use precise words so meaning is conveyed clearly, otherwise we descend down the slippery slope to moral relativism where we define “right” and “wrong” by the intention of the actor, or the desirability of the results, or the convenience of the act.
There is no difference in lying to a corporation. The owners of a corporation are people, the shareholders. The people you don’t like, that you find evil, are not usually the shareholders, which are largely the retirement plans of ordinary people, but rather the executives and directors. None of whom suffer any significant loss by your lying to them, they’ll just go work somewhere else when the shareholders lose their investment because the corporation folds.
I do believe “right” and “wrong,” except to clinically ill people like sociopaths, are self-evident truths. That is why so many people go to such great lengths to try to redefine “wrong” as “right,” because their consciences at some level know they are wrong. I believe this is true across all cultures and societies, but that each culture and society chooses to what degree to hold themselves responsible for each “right” and “wrong.” As an example, I have found certain cultures have a greater acceptance than others of lying in business transactions. I do not believe these cultures believe this is “right,” but I do believe the culture has chosen to permit this “wrong” to escape consequences.
