Well it seems to me that reputable scientists adopt it as a working hypothesis: not as a fact.
Of course, the majoriety of scientists do. But that is not who I am critisisng. Rather, the people who take science's hypothesises
as fact, rather thanlike a fact devived from empirical sences that seems to be the best possible explanation as of now. In pratical life, yes. I am happy for this to be accepted. After all, if we take the example of hume's sceptism where let us hypothetically imagine a house has a bomb in it. A friend phones to tell the owner that he needs to get out before it explodes. The owner replies that because he is not feeling it via the sences it doesn't exist and puts the phone down. It would be stupid in my view to live your life like this, and since it is most likely that the bomb is in the owners house, it is better to take the chance of fleeing rather than staying. My quarel is the theoretical implications rather than the pragmatic. I am not attacking the report, which seems pragmatic.

I am perfectly happy to concede that most of what we know is probability not certainty. So if we accept that, what now? There are possibilities:
1. There is the option to say that we cannot act on any of what we know. Even verification through our senses is not certain: we may be drugged or dreaming or hallucinating for some other reason. To me that stance renders life narrow and boring. Solipsism is objectionable for many reasons: but mainly it is lonely. And that paralysis leads to stagnation.

To this, I believe we cannot know anything. Or at least if it is true or not. But do we really need truth to live. Personally I think not, but what is only
like truth that acts as a guide for our actions. On the contray to me, a life of doubt leads to a life of possibility and wonders. As for soliphism, I'll object to it due to more the pragmatic reasons rather than the emoutinal. I prefer Kant's idea of the noumenal and phenomenal.

2. We can do what is normally done: we can act "as if" what we know is true, and see where that takes us. It gets us quite far, I would argue. "If" cholera is a disease which accounts for several deaths in one location then we can try to see what makes a difference to the number of deaths. "If" it is a disease, and it is directly inflicted by an angry God, we can pray or make human sacrifices or whatever, to see if we can jolly him into a good mood. "If" it is a disease and it is caused by contaminated water, we can try to clean the water and see if that makes a difference. The latter works and the former does not. So those theories do not have equal status.
To me, the status of the argumant is derived from the methords and reasoning used. Since such acts are done using empirical devices then they credibility is souly dependant on the empirical world. Which is fine, since we live in the empirical world it can be argued, or are at least observers of it. So why wouldn't we come to this conclusion.
QUOTE
You may prefer to say that they do: I think that is silly. But it does not change the fact that neither theory is "known" in the sense of being certain. At least not by the criterion of "verification" through the senses. For all we know God is pleased by boiled water, and there is no such thing as a disease organism. That we can now see what we think of as disease organisms is no guarantee they exist: God could have put them there to fool us, just as he did with fossils and holes in our socks. But it is not very likely.
Again, I would argue that the likeliness of such a thing would depend on the sphere of existance of which the conclusion is made.

Have you read Gulliver's travels? If so you will remember Laputa. Swift lampooned the consequences of your second objection. There was a scientist there who was researching how to get sunbeams out of cucumbers: he had been at it for years. There was no reason to suppose he was ever going to succeed, nor any reason to think he was ever going to stop trying. If nothing can go faster than the speed of light there is no point in diverting resources on the assumption that it can.
I never implied we should. From a pragmatic stance, such a thing would be foolish.
QUOTE
It follows from what I have said that I think you have misunderstood the position of most, and what you are objecting to is a straw man. It is certainly true that some of what we teach children is simplified, and presented as unquestionable. That is not predicated on a misunderstanding of what and how we "know": it is predicated on our judgement of what they can grasp as they grow.
Personally, I do not like this. A person I knew when he was in school was in a science lesson, and they were disscussing the idea of
absolute zero. The teacher said that when matter reaches this, it stops moving completely. My friend then went of to hypothesise that at some point, on an unbelivabley small level that matter would still be moving. Hense, it could never reach
absolute zero because of this. This is because he believed than a variation of
zeno's paradox of motion applied to the amount of energy in something as well. That no matter what it appeared to look like, they'd would still be some energy left over. The teacher however just appealed to the authoriety of scientists and got him to shut up. Whenever he was right or wrong or not is not my point here, but instead of discussing the proposition or not, or even allowing doubt on the matter the teacher just shut him up. Personally, I would like to see more debate in schools and less
here's what you need to know, learn it kind of stuff. I believe the magazine
philosophy now was setting up philosophy classes in primary schools to get children to think outside the box, and with good results. There must always be room for doubt for me unless we want to end up as mear machines.
But anyway, I have straid. It is not children I am not so concerned about, but people manipulating science for there own ends because it is seen as some sort of magical cure that will solve all of humanities problems, rather than a logical process based on empirical phenomina.
QUOTE
Nobody can verify everything for themselves: we haven't time. If we did foster such an expectation we would have a very high death rate while children tested their various hypotheses about fire and gravity and strangers. Can't see any merit in that at all. So far as I can see we are social animals and we pass on a great deal through cultural transmission. And that is a good thing, on the whole. As we mature we find out that not all things presented as certainties are: and later that almost none of them are. Welcome to the adult world, at that point
I never implied we could verify everything ourselves.
Good in ethical context, or self-intrested context?
QUOTE
It is also true that some people never reach what I am shorthanding as adulthood. They are perhaps unfortunate in never realising that the simplifications and prescriptions of childhood are for the purpose of keeping them safe in various ways; and they either cling to the "certainties" they were given: or they reject all of it and are left with no bathwater and no baby. Most of us go through a stage of the latter in adolescence and I think that is a maturational stage for developing human beings: but it is not a very useful end point for the reasons I have given.
Agreed, but what I worry about is people manipuating other people who use such simplifications and claim it good and right to do so.
Fair enough, I hope I haven't used to many fallicies in my responce.
