Let's see. There is a difference between qualitative information and quantitative information. Mathematics and that which is relative to numbers and quantities is not open to interpretation, therefore it is certainly not open to debate. This is why modern science is based on quantitative research.
On the other hand, not everything can be quantified, and it is that which is relative to the qualities, the what, the how, the why, and so on.
Quantitative information is what is usually called "facts", and what nobody disputes. However, numbers alone don't do much good, and when you try to take them to other fields, the qualitative, hence the interpretation, comes into play.
What you call "facts" when you speak of needs, or when we speak of qualitative aspects, cannot be called facts, is the principle of falsifiability.
When we talk about what, why, and all these things, we only talk about opinions, opinions some more true than others, but always opinions and not truths.
Having clarified this, let's look at the needs.
There is a difference between defining what is the state of necessity, and the need itself. We both agree that in a state of necessity an act that would commonly be considered immoral is justified, right? the dispute would be in what we consider necessity.
People can not define for themselves when they are in need or not, is what I believe, because they can arbitrarily do immoral acts when they are not in real need, however, justifying themselves saying they are needed.
First they steal some shoes because their toes are going to fall off, and then they steal a pair of new shoes because the ones they have can wear out soon and then they will need to steal a pair again, they are foreseeing, and so on, because the change is subtle.
When do I believe that they would be in real need? When they can not discern if what they do is right or wrong. Why do I keep saying this? Because if they know they have other options, then the choice is already arbitrary. When there is no distinction between what is necessary and what is correct, there are really no options. When there are several options, people can deceive themselves to take the easier option saying that they are in need when they really are not.
Also, if people know that what they are doing is not correct, they are able to take other option, because as I said, if they were not, they would believe that there is no such option.
I think I've been quite clear and direct this time. If you think I miss something or that there is an inconsistency, or if you have any refutation to do what I said, I wait for it.
