So if someone does not doubt that 2+2 is 4, do we discount this as a belief becasue it is indubitable? — Banno
"Indubitable" summons Descartes, so from Mediations:
“I clearly and distinctly perceive that existence is contained in the idea of God, just as clearly and distinctly as I perceive that the equality of its three angles to two right angles is contained in the idea of a triangle.”
This speaks to the logically necessary and therefore indubitable (which he includes geometry and God), which i suspect is different from a Wittgensteinian hinge indubitable, meaning those things we can't question in a game playing arena. Those would be foundational rules. And I think of Kantian intuitions, also indubitable (e.g. time and space), but only insofar as necessary to provide us any ability to understand the world.
The point is you're asking about "on certainty" and how that is a different category than belief, and this question seems central to Western philosophy in terms of asking what we can debate and what we cannot across different founding father philosophers (as it were).
But nothing is straight forward because some do challenge whether the indubitable can be doubted. Consider transubstantiation, that miraculous concept pondered for thousands of years how the trinity can be a unity, leaving us with a word called 'triunity."
And I do think the major challenges will come from religion because it posits a very different view toward knowledge justifications (i.e. faith versus rationalism/empiricism).
Or do we say instead that because he will not act on what he holds to be true, that he doesn't really believe? — Banno
My father, despite his very scientific background, would not fly on airplanes, would not ride glass elevators, and insisted upon lower floors in hotels so he could make it out before being consumed by the one in a million hotel fire. I truly don't know what he believed. Curiously, he died a fiery death when an airplane struck him on the 40th floor of a hotel while, you guessed it, in a glass elevator (a joke). Phobias don't strike me as beliefs as much as just irrational fear, rooted in the psyche, maladapting to something in the past. I once asked him why he'd get on a ship and not a plane. He told me he could swim but couldn't fly, and he was super proud of that retort. Beats me.

Playing the lotto is rational if you wish to win because you can't win if you don't play. Believing you will win is a different matter. Maybe some believe they'll actually win, like some believe they'll one day become a princess or rock star or whatever fantasy one might have. And let's not overlook the pessimists who are sure they'll fail despite all they have going for them.
I suspect this has to do with the J of K=JTB, where it is inherently subjective. That is, if I give a justification for my belief, it can count as knowledge, and my justification is valid if I subjectively accept it. If I believe I'll win the lotto because I believe myself God's special creature, then it's belief. I dont think McCormick can deny certain justifications for belief as invalid justvbecause they contain an emotive basis. I can believe for whatever stupid reason i want. . That won't make a non belief. That will just make it a stupid belief. But a belief nonetheless.
David's belief is not to be subjected to doubt. What are we to say here - again, that it's not a proper belief becasue it is indubitable? — Banno
This is faith based belief, the topic of a whole other thread. Those of certain religious worldviews would see this one as so obviously intertwined with the mystical, the emotive, the super rational, that McCormick 's thesis would appear elementary. That is, no kidding, my belief in God relies upon justifications a non-believer would never accept?
