My base belief is that what people believe is their truth, and rhetoric is a primary way to convince them. Part of the rhetorical mechanism is to introduce evidence, but this, too, is shrouded in rhetoric.
I’m not talking about the evidence that ‘standard’ water boils at 100°C at sea-level. This is tautological. Water is defined as H₂O. Literally, 100°C is the definition of where water boils under these conditions.
But things that cannot be repeated in controlled environment with the ability to alter parameters within the environment rely on rhetoric. This is why Newton’s laws seemed som compelling until a new narrative (somewhat) supplanted it. Still, this is not the point I want to make. I want to concentrate on the socio-poliotical domain.
I feel that given two equally viable explanations, the one offering more hope will prevail. Donald Trump knows this. This is why in the midst of the COVID-19 pandemic, he railed at a presser how he chastised a reporter for questioning his (false) narrative of hope. Politics relies on more than one rhetorical thread, and many already have the disposition of reviling Trump, so any messages from him are discounted at the start.* But, ceteris paribus, if a person assesses two equally probable outcomes—a typical door number 1 or door number 2 scenario—, and (for whatever exogenous reason) hope is associated to particular door.
In a survival scenario, perhaps you are one of three people lost in a cave and there are two possible paths forward. One person asserts that s/he feels that—without evidence—the left path is best way out but adds logically there is no way to tell, that you might as well flip a coin. The other person confidently conveys that s/he knows—without evidence—that the right path is the path to salvation. Being otherwise indifferent, you are likely to acquiesce to the second person, the one who offers hope over logic.
I fully admit that this is 100 per cent fabricated whole cloth from thin air, but the reason I come to this point is when you compare atheists to theists, anarchists to statists, nihilists to Existentialists, and any such analogic pair, the right side gets more traction and requires much more evidence to sway people to the left.
So when Occupy Wall Street (effectively anarchists) made demands, the status (read: the general population) asked ‘Who’s your leader?’ When the media-industrial complex broadcast this, the public was immediately sympathetic to the structured system. This is slightly different in that it’s not necessarily hope, rather a comfort zone—an endowment effect. It’s a benefit accruing to the incumbent.
My point is: hope floats. It acts to buoy otherwise rhetorically equivalent arguments. Or perhaps hope is simply an employed rhetorical device, so it’s unnecessary to call it out. Now, I’ve convinced myself to adopt this position.
* This is why ad hominem attacks can be effective, as persons swayed by the attack discount messages delivered by this person despite there not being a necessary connection between the grounds for debasement and the claim being asserted.
