No. It means that you can't set up a test to prove that it is false. That's not the same as you can't know if it's true.
It is, actually.
When a claim is falsifiable, this means that its truth would have implications or predictions we can test or observe.
Testing the predictions of a claim is also the way we figure out whether something's true.
So that means there's a falsifiable test we can do on religion. Do you have an example of such a test?
Sure. The religious claim that the Earth is only 6,000 years old is falsifiable in a number of ways (dendochronology, for instance). Faith healing claims can be falsified by carefully testing the person being "healed" before and after the "healing" to confirm that they really did have the ailment beforehand and didn't have it after.
So there's a test you can do that if it was proven true it would prove these things false?
Not right this minute, but neurology has things to say about the ideas of "mind" and "soul".
The claim that souls exist implies that there is something that is genuinely "me" apart from the actions of the brain. If the mind - i.e. me - is just "what the brain does" as modern neurology is strongly suggesting, then there's no room for a soul.
Rational isn't the same is falsifiable. Something being rational doesn't make it falsifiable.
Wiki defines falsifiable as: "Falsifiability or refutability of a statement, hypothesis, or theory is an inherent possibility to prove it to be false. A statement is called falsifiable if it is possible to conceive an observation or an argument which proves the statement in question to be false. In this sense, falsify is synonymous with nullify, meaning not "to commit fraud" but "show to be false". Some philosophers argue that science must be falsifiable.[1]"
Right. So if a conclusion is derived from evidence - which I would say is one element of it being rational - then it's falsifiable.
How is that falsifiable? Can you come up with a test that could prove that I don't like ice cream?
I'm an engineer, not a behavioural economist. I'm not sure I'd be able to design an iron-clad test, but I have confidence that someone who could measure
health care and risk preferences or
the relative importance of housing prices versus non-monetary factors in school preferences could figure out a way to test your food preferences.
It has to be an objective test, or it's not considered a falsifiable test.
Now you're just making stuff up. It's definitely falsifiable to you.
I tried some ice cream. I liked it.
Sounds like your claim is reasonable, then.
So I didn't falsify it. It wasn't a falsifiable test. The test must be in the opposite. It has to be a test that comes out true to make the overall claim false, but if the test comes out false, it doesn't imply the overall claim is automatically true.
If you taste the ice cream and realize it tastes awful to you, then the claim that you like ice cream would be falsified.
That doesn't matter. A true claim is a true claim. A claim is a claim. Falsifiability is a matter of being able to create a test which would prove the claim false if the test is positive.
"God exists" is not a falsifiable claim. You can't create a test that if the test comes out positive it would prove God's non-existence. That test doesn't exist. It's the same for belief. Belief in something cannot be falsified. It's a subjective experience and a subjective idea.
"God exists" is also not the sum total of any believer's beliefs. For anyone who has a real religious belief, their belief system includes claims like "God exists and has attributes X, Y, and Z", or "God exists, and he's done A, B, and C."
At the very least, a believer's answer to the question "why do you believe in God?" either points to a testable claim or to the fact that the belief is improperly founded.
