But what huge uproars were caused when the earth was proven to be round!! The church had a conniption. It took time to change the collective mind. I agree with you about faith. Faith is the evidence of things not seen. It also makes up our beliefs, probably our most zealous ones, which is why religion incites the worst wars.For example, people used to believe that the world was flat. Show them a picture of a spherical earth and they'll change their belief. Faith is something else. It is belief without evidence.
Let's leave animals out of this discourse. It introduces too many variables for a logical and consistent argument. A screaming baby is laying in his beliefs. If his mother does not console him, feed him, or nurture him, his belief will become one of, "My mommy is not here for me when I cry," and he will adapt accordingly. He will come to believe that mommy isn't there for him when he cries, so he either has to do something else for mommy's attention, or learn to live without it. This adaptation will, if it has to be used often enough, follow him into adult life and be part of his deep-seated belief system, even if he is not conscious of it; indeed he likely will not be conscious of it.If you have ever tried to console a terrified animal, or even a screaming baby, you would know that rational thought doesn't come into it.
