Belief should not be absolute, but a matter of degree. If I flip a coin ten times, I believe that it'll land heads at least once. How strongly do I believe it? As a matter of fact, I'm a little more than 99.9% sure. The probability of getting at least one head is 1023/1024. On more complex things, it's harder (and sometimes uncomputable) to come up with such precise probability estimates, but that doesn't change the…
Evolution is a good example. Why do you believe it happened? Because someone told you. You read someone else's words. It sort of makes sense. You saw what you assume are dinosaur bones in a museum. All of that is faith, and perhaps blind faith. I'm assuming you're not a geneticist, so you probably didn't verify that the bones that were stacked nicely into a skeleton actually came from the same being. You likely weren…
For example, I accept on "blind faith" the fact that Australia exists. But if I got on a plane to Australia, I have every reason to expect that it will go to a real place called Australia, rather than secretly taking me to Botswana or something. By your definition, a belief in Australia and a belief in unicorns are both lumped under the category of blind faith, which I think is a really silly classification.
All our observations of the world -- even sight, sound, smell, and so on -- are indirect. Your eyes don't see all wavelengths, and they can be tricked into confusing combinations of red, green, and blue as "the same color" as a pure wavelength of light. And don't get me started on the preprocessing that happens before the signals even reach your brain! Will you categorize everything you see as being taken on blind faith as well? Where do you draw the line?
