How much of science is faith based?

In summary: At some point you will run out of evidence, and then all that's left is persuasion.In science, we don't just rely on one piece of evidence. We look at the big picture and consider all the evidence we have gathered. That's why it's a constantly evolving process. And persuasion has no place in science, only evidence and reasoning. In summary, the conversation discussed the role of science and faith in society, as well as the concept of evidence in determining the validity of beliefs. The speaker argued that science is based on evidence, while faith is based on belief without evidence. The conversation also touched on the idea of evidence building upon itself in science, while the concept of faith relies on persuasion.

JoeDawg, read what I have posted: I do NOT make use of induction, but deduction.

Then you're not addressing the problem of whether the future will resemble the past. What you have described is what Karl Popper tried to do with falsification. Its a very compelling argument, but ultimately falls short.

If you meant something else, you will have to explain it further.

No, it does not "fall short" since how I have shown how we can be sure that the sun will rise tomorrow by deduction.

Oh, actually I was thinking you meant the god-infinite-regress problem.

I think Descartes did a good job on the epistemological side, at least in the beginning of his meditations. Which part are you disagreeing with?
Summarizing my understanding, foundationalism and coherentism are the leading responses to the regress problem. The foundationalists simply stop rationalizing and say "we will accept these postulates". The coherentists stop rationalizing and say "we will accept this belief system". (And based on my experience with formal logic, I would actually assert that the two philosophies are the same)

My point is that both philosophies admit defeat, and give up the notion that their beliefs can always be justified in terms of "higher" principles: the foundationalists simply write down a list of principles they will accept without justification, and the coherentists argue that their beliefs, taken as a whole, are coherent and thus self-justifying.

(I'm not familiar with what Descartes actually wrote, so I can't comment on that)


For many (most?) religions, a religious person can cast their belief in their religion as foundationaist, coherentist, or possibly some blend of it.

You argue that the scientist's belief in science is a "reasoned belief", and thus somehow different than the religious person's belief -- so I'm asking you to please elaborate.

To say "Uncertainty over-rules faith" would be an incorrect statement... although it would also explain what you guys keep repeating.

The statement would be incorrect because "faith" is a condition bourn of the cognitive processes and has nothing to do with "external" events.

The statement would be correct only because it is the short form of "not knowing if the rock with fall, the nose will be picked, the sun will rise" next time history dictates that it will.

Therefore I'd ask that you people remember how "faith" is a carefully developed cognitive state, belonging only to the individual who has decided to develop it... with whatever help they seek out.

Science is a specific approach to the study of internal and external conditions and is based only on the specific tenants of those disciplines that comprise science. To ask if science is "faith-based" in any way is like asking if science is "hope-based" or "stress-based" because each and every individual that practices scientific inquiry will approach their study differently. The diversity of methods of coping with the disciplines involved in the sciences should illustrate that there is no "hope-based", "stress-based", "faith-based" or other basic cognitive condition required to study science.

Science, itself, is "science-based" and nothing more.

Descartes was a foundationalist I suppose, in the sense he claimed one thing as being 'self-evident'. This claim is generally understood with the phrase: I think therefore I am.
Or more specifically: thought exists
(ref. Descartes: Meditations on First Philosophy)

He believed all knowledge is built on this 'first principle'. I agree, although we part ways later on...

That said I'm not an ardent rationalist, I'm very much in agreement with classical empiricism, but Descartes is the undeniable starting point, in my opinion.
You argue that the scientist's belief in science is a "reasoned belief", and thus somehow different than the religious person's belief -- so I'm asking you to please elaborate.

Once you have the 'thinking' foundation, then one can start distinguishing between modes of thought and then perception. Then science comes into play as a measure of what, if anything, is consistent amongst perceptions. This may be where coherentism comes in, although from what I have read both terms are used in a variety of ways.

Now that is all a gross oversimplification, but I'm summarizing.
The important part is that it does have a logical progression.

Religion by its nature has no logical progression, religion is 'revelation'. Gods tell us unquestionable truth and we are asked to believe.
Kill your son because god commands it.
Love your neighbor because god commands it.
Seek salvation...etc...

I believe that is a huge difference.

http://en.wikipedia.org/wiki/Problem_of_induction

"Karl Popper, an influential philosopher of science, sought to resolve the problem in the context of the scientific method, in part by arguing that science does not rely on induction, but exclusively upon deduction, in effect making modus tollens the centerpiece of his theory. On this account, when assessing a theory, one should pay only heed to data which is in disagreement with the theory rather than to data which is in agreement with it. Popper went further and stated that a hypothesis which does not allow for experimental tests of falsity is outside the bounds of empirical science.

Wesley C. Salmon critiques Popper's solution to induction by arguing that by using corroborated theories induction is being used. Salmon stated "Modus tollens without corroboration is empty; modus tollens with corroboration is induction" [3]"

Do you have any evidence for this? And science is based on evidence by the way. Evidence does not equal faith.

The Greater the evidence, the greater the faith you will have... You have faith in science, don't you? Why? Because it gave you evidence... You will trust anything that gives you evidence... But some people don't bother looking for evidence, resulting in worthless faith... You need evidence to have faith that actually has some worth...

Although we certainly have not well defined the word "faith" in this thread, I doubt this is a common definition. In this context, it appears you are using the word "faith" to mean "belief in that which is most probable".

For the gazillionth time, I have just deduction, not induction. Copy-pasting from Wikipedia (:rolleyes:) will not change that fact, Furthermore, critic of induction rests on induction itself, so it is pretty much useless.

The problem here is that they actually do not give up; people claiming the justification regress will then also have a justification regress to justify their own claims of justification regress. How can you justify your support of justification regress?

All induction and deduction must be based at some point on inductively obtained statements--because everything is empirical.

Yes, but that has nothing to do with the deductive argument I posted. The premise has a massive amount of evidence in its favor and none against it. Only a lunatic would say: "well, I still think the sun will not rise tomorrow".

At one point we (and I have the temptation in me as well) found it easy to say things like, "only a lunatic would think there were tiny animals swimming in a drop of pond water" and "only a lunatic would think a doctor washing his hands between patients would reduce the spread of disease". Now you may accuse those scientists of being unscientific because they didn't do a good job of estimating the probability of truth in the statements, or they simply didn't have the data to realize they were wrong. And maybe modern science is a bit wiser in that respect. But consider this: There are some pretty smart people in the world arguing over a lot of things "religiously" (by that I mean they each are convinced the other is a lunatic). This should be proof enough that we are still susceptible to bias, faith, arrogance, etc. (myself included). Its certainly OK to make sweeping statements in casual conversation when the probability of them being false is extremely remote, but all I ask is that we do spend just a little time now and then staring out a window and contemplating whether 2+2 really does equal 4, or whether that statement even has that much meaning.

For what it's worth, here's my 2 cents.

There's a difference between lack of knowledge and contradictory evidence. Back then, there was no way for people to experimentally verify if there were tiny animals actually swimming in a drop of pond water. So, whatever claim someone made about tiny animals swimming in a drop of pond water, it's irrelevant from a scientific point of view, because people didn't have the means to verify the claim. Once people had microscopes and were able to perform experiments, it become clear that there were tiny organisms swimming around.

But, this is different from what most religious people argue. People may say that they believe praying to a personal deity cures illness. However, when rigorous controlled tests are done to test this claim, it's seen that prayer doesn't cure illness. Yet, people still believe that prayer cures illness. I call this an example of faith, which is very different from science.

Also, I don't think there's any "faith" involved in the claim that the universe has some structure and that science is attempting to find laws which describe that structure.

Once people had microscopes and were able to perform experiments, it become clear that there were tiny organisms swimming around.

But take a look at the timeline. For a long time microscopes were readily available while there was substantial resistance to the microbe theory. Likewise for a long time soap was available to doctors while there was substantial resistance to the microbial theory of disease.

But, this is different from what most religious people argue. People may say that they believe praying to a personal deity cures illness. However, when rigorous controlled tests are done to test this claim, it's seen that prayer doesn't cure illness. Yet, people still believe that prayer cures illness. I call this an example of faith, which is very different from science.

I provided an example of a large number of scientists being wrong for a long time to prove that a large number of scientists can be wrong for a long time (because of faulty logic and arrogance--not lack of knowledge), and thus we might well be susceptible to the same thing. Providing an example of commonly believed low-probability statement (assuming your claim is correct) does not change the fact that a lot of scientists can be wrong for a long time or that we might be susceptible to the same thing. If anything, it reinforces it--its human nature.

Also, I don't think there's any "faith" involved in the claim that the universe has some structure and that science is attempting to find laws which describe that structure.

Good point, My eyes are opened. I've been making the statement "nothing is provable because everything is empirical", but now I must admit that "I think therefore I am" proves absolutely (100%) the truth in the statement, "there is at least some order". But also note that proving beyond doubt there is some order does not prove anything about the nature of that order--which is where our arrogance and faith in other axioms (my own arrogance included) can still bite us in the end, like it did those scientists I mentioned.

i'm just wondering does the scientist not believe that when he applies the scientific method he applies it to SOMETHING physical? So then without 'faith' the scientist would just be finding out information what a mass of people consider to be 'reality.' They don't say that though they say it more as if it is TRUTH of the physical world. So faith must exist?

and i don't understand why people are ignorant enough to say faith ONLY applies to 'religious' beliefs. I don't see how you can back that up given the definition of faith...

I think foundationalism is the right idea. Regress is not something to be overcome; it is an essential flaw in the naive way of viewing things, and compels us to adopt a more sophisticated treatment.

Yes. For the religions I'm familiar with, there is no (known) fundamental incompatability, and no emergent incompatability has been demonstrated.

I agree with Hurkyl, there is no reason why you can't be religious and also understand the science behind things. I think the problem lies primarily with a small group of Christian fundamentalists (vocal minority) that take the bible to be literally true. They seem to be the ones that find scientific explanations to be in opposition to what they believe is true.
 
  • #202

I would not so much label them as incompatible (as there obviously are people who are both scientists and theists), but as irreconcilable because one cannot interchange methods and theories of knowledge between science on the one hand, and religion / theism on the other.

To claim that, for instance, that the dinosaurs where killed by an asteroid because one had a revelation, that it is written in a religious scripture or a religious authority has promulgated an official dogma establishing it would be insane. Likewise, subjecting religion / theism to the same level of positive skepticism, reasoning, critical though, demand for evidence and coherence as one does in science, would probably make it fall like a house of cards?

The best one could hope for was some sort of non-overlapping magisteria, such as that Evo mentioned above.

As an interesting factoid, some 43 % of the US population do not accept evolution

interestingly enough most of them probably come from the bible belt and states in southern america have the highest illiteracy rate (up to 63% illiterate in some cities and 50% for states (mississippi)) maybe some sort of connection?

I think science and deism are compatible, but I am undecided when it comes to other forms of theism. More specifically, it is not obvious to me whether science and fideism are fundamentally compatible as two basic beliefs. I often struggle with this question, so I hope someone can share their insight.

I am uncomfortable with the idea that one can justify a belief using fideism (e.g. believe without reason), and yet accept science (e.g. reason) as an equally valid form of justification. Thus, I am inclined to argue that science and fideism are incompatible basic beliefs. What do you think?

Belief without a reason? I'm not convinced that such a thing could exist either! We may have poor reasons for our beliefs, but "no reasons" does not compute. Please explain. I have not heard this term before. Thanks!

Discomfort is not proof against. :smile: Maybe it would help to start with a more familiar example of trying to reconsile methods of justification?

Consider rationalism (truth comes from logical deduction) and empiricism (truth comes from experience). If you take either of them strictly, then they are clearly incompatable. But the two can be used in concert -- for example, as used in science. (Science is not pure reason!)


(Incidentally, I don't think "truth", as used outside of mathematics, is a very meaningful notion)

Agree with all of this. But I was recently corrected on my frequent statements, "Everything we know was obtained inductively, so nothing is 100% provable". The correction is that "I think, therefore I am" is 100% proof of the statement, "there is at least some order". Of course, it proves nothing about the nature of that order.

Humans are capable of adapting to different cultures simultaneously. It happens all the time. For example people usually behave differently in the internet than in the physical world. But besides this, also in the physical world, people behave in certain ways in certain places, and in other ways in other places.

Believing in the religious beliefs is in contradiction with the scientifical method, because there you accept to believe in something without reasonable evidence. You have faith because you got used to having faith when you were young, and because you have been taught to have faith by religious authorities.

What happens with religious scientifical people is that they behave differently at different contexes. They (and you I might guess...) apply the scientifical method to those questions where you have got used them being applied, but not with the religious questions. That means, that you have adapted to two different ways of thinking (and two different cultures).

That is of course lot better, than applying religious principles to obviously purely scientifical questions, which is catastrophical, but it would be simply the best to be just as scientifical as possible always.

Belief is a mental state. To believe in proposition X is to think that X is true.

Reason is used synonymously with justification in the context of foundationalism.

An Agnostic Theist would be an example of someone who believes without reason. In particular, they believe in the existence of god(s), but at the same time, acknowledge that it is an unjustified belief. In other words, it is a belief outside the realms of knowledge. I hope it is clear now. :smile:

I often struggle with this question, so I hope someone can share their insight.

I generally consider any form of deism to be a weak statement in that it doesn't say that much more than 'well, one or more deities did it, but now nature is on its own'. It is almost as the deist definition is more like nature itself. But interesting nonetheless.

Consider rationalism (truth comes from logical deduction) and empiricism (truth comes from experience). If you take either of them strictly, then they are clearly incompatable. But the two can be used in concert -- for example, as used in science. (Science is not pure reason!)

I do not agree with those definitions. Both empiricism and rationalism are truth from experience, just different kinds of results from experience. Rationalism are experience (which everyone must start with as their basis) plus the adaption of logical deduction, whereas empiricism is experience plus sensory perception through observation and experiments.

In this manner, "experience" =/= observation and experiments, but what your brain experiences as input.

(Incidentally, I don't think "truth", as used outside of mathematics, is a very meaningful notion)

You actually need to adopt the a priori validity of the concept of truth to do anything. "Truth" is simple based on the amount of predictions a given idea succeeds in making for your experience. The more predictions its satisfies (think as a forensic analyst), the larger the degree of confidence it has.

Occam's razor obliges the atheist to defend his claim that reality includes some arbitrarily extra mechanism that precludes the existence of infinite order. For surely infinite order should be called "God".

What lead you to that definition? What is the justification of that definition? Why not some other definition? What does "infinite" mean? What does "order" mean? Before those questions are answered, you will get nowhere, as will randomly postulating the existence of infinite order.

Occam's razor actually cuts against the unnecessary multiplication of entities that offer no extra explanatory power or predictive power. Let us take an example. Imagine a ticking watch. The most logical explanation is that it is driven by cogs and the processes of mechanics. You could, of course, argue that there are magical, invisible aliens hidden inside the clock mimicking the processes of mechanics. The aliens are a multiplication of entities with no explanatory or predictive power and is therefore cut by Occam's Razor.
