So, just to recap a little here. The principle of induction is a principle that animals have as well as humans and it is precisely that we trust or believe that if things happened a certain way repeatedly, then they will continue to do so in the future. There is not really a "reason" to expect that but there is the fact that when things happen repeatedly, we expect them to keep happening the same way.

That's an expectation derived from evidence. Thus, at least using the definitions I use, it is an antithesis of faith. Faith requires a belief in spite of a there being a lack of evidence or contradictory evidence.

The difference being, if a repeatable phenomenon does not repeat, a person's expectations simply change as the new evidence is included. This is based in proof, not faith, as faith requires some sort of apprehension or trust in something beyond the evidence. Thus, for a person using probability to influence their expectations, their understanding of the world is far more robust and flexible than one using faith.

I don't get on an airplane because I have faith in the pilot. I do it because the repeated phenomenon of planes landing safely allows me to adjust my expectations accordingly. I'd a plane crashes somewhere in the world, I would still probably be willing to get on a plane the next day, as the probability barely changes. If I had faith that airplanes don't crash, that faith would be far more shaken, as it seems that they do.

Similarly, I do not have faith that the sun will rise tomorrow, as I understand that the sun is a celestial object that could be subject to any number of extremely rare astrological phenomenon that would destroy it. I do, however, expect the sun to rise, as I understand the probability of such an event is low.

Yes, but why do you expect astrological phenomenons to be the same tomorrow? Why do you expect gravity to function as it functions today tomorrow?
