Belief: something held to be true whether or not there is evidence it is true.
Which dictionary are you getting that definition from?
His view is NOT new Covenant... It has been an open question for as long as there have been philosophers. See the wikipedia page on Epistemology.
The core difference between truth and belief, is that truth is independent of any observer, at least according to the school of thought that Max subscribes to. EG, the light scattering properties of oxygen atoms will remain the same, even if nobody is there to see the scattered light. Compare this with "They sky is blue". This is how it sidesteps things like qualia. (How do you know that what I see as blue, is what you see as blue?, et al) "The sky is blue" is a belief, but a well reasoned one. "The scattering properties of oxygen" is a truth (or real knowledge).
The notion that a truth can be a well reasoned belief comes from antiquity, and is deeply rooted in precepts from that age. It does not really work when held against the notion that there is an objective reality outside of any observer that will continue to persist as it is without observation by any observer, however. This makes this kind of definition pretty much incompatible with a scientific worldview-- The scientific worldview discards any notion of solipsism, while the "well reasoned beliefs are truths" school from antiquity embraces that as a valid option.
Outside of very rigid intellectual circles, Max's views on knowledge are not commonplace, which is why you are confused by them, and insist he is redefining the terms he uses. Then again, outside of rigid intellectual circles, the belief in the supernatural being real is commonplace.
So, which dictionary did he get his definitions from? He already told you-- He subscribes to a specific mindset, concerning epistemology. He even named names.

Back on topic, RE: lemonpie.
That is exactly what I have been meaning, when I say that imposing limits on suffrage's *FEATURE*, is the removal of voices. That is the "benefit.", the thing one seeks.
However, intrinsically, this process denies a group representation by being implemented, and is thus officious and authoritarian in nature, not democratic. Democracies are less concerned with objective truths, and more concerned with popular will, which is where the demo- in democracy is operative.
When you combine this with historic tendencies of authoritarianism, you end up with a government that does not stick to objective truths (because truths can become whatever the prevailing power base SAYS they are, end of discussion, actual objectivity be damned-- you have no voice to challenge it with!), and does not permit any questioning of its conclusions. If your goal is a balanced and empowering society, limits on suffrage are not a feature, no matter how enticing the notion of shutting people up might be.
Even in academic circles, the slavish adherence to authority (which is what you are proposing would ACTUALLY be) is not optimal. If we did that, we would never have given ear to Einstein, and would still be trying to reconcile the Ptolemaic universe with reality. A dissenting voice needs to offer proof before being taken seriously, but the authority is reality itself, not an "in-crowd"-- though often haughty humans forget this, and you end up with "not science" as a result.
Being assailed on all sides, all the times, and always challenged is how science stays on the straight and narrow. Dont fall victim to ascribing to an "appeal to authority" type logical fallacy, by asserting that "experts" always know or do the best things. When they stop being questioned, and held against objectivity through that questioning, there is considerable utility (many perks) in inventing an official narrative, objective reality be damned-- which is why it has, without exception, devolved into that mess every time it has been attempted.
Those most likely to "just love" limits on suffrage are those that do not like being questioned, or subjected to questioning. They are the most vulnerable to getting trapped in circles of biased thinking, and official narrative, and are the most likely to cease being objective thinkers or operators. Embracing that endless exposure to chaotic challenges, no matter how naive the challenges may be, is how you remain rigorous mentally, and stay objective. The objective person will realize this, and reject the siren song of silencing those dissenting voices.
