“Now, in this tortured model one sees that it is possible to have retrograde motion and varying brightness, since at times as viewed from the earth the planet can appear to move “backward” on the celestial sphere. Obviously, the distance of the planet from the Earth also varies with time, which leads to variations in brightness. Thus, the idea of uniform circular motion is saved (at least in some sense) by this scheme, and it allows a description of retrograde motion and varying planetary brightness.”

Rationality is a beautiful method of relating to the outside world.
It is one of the tools we used to get where we are now.

And, like all other tools, it has its limits.

The most ‘stricturing’ one being the fact that rationality is used by us, individual people.

We are deluding ourselves with the notion that we are rational, reasonable even, human beings. That given the same set of facts each of us is potentially able to find the same ‘truth of the matter’ and only those who are ill indented will reach a different conclusion.

Ptolemy’s epicycles are just a set of the innumerable proofs that we are nothing but skillful rationalizers, far away from the reasonable individuals we believe ourselves to be.

Sallustius to the rescue:

The ‘things that never happened, but always are’ are the founding myths that keeps it all together for us. From the axioms on which we have built our mathematics to the religious beliefs we have forged while grooming ourselves into humans.

What happens is that not all of us have been groomed along the same myths, and even when that happened not all of us interpret a given myth in exactly the same way.

That’s why Ptolemy had invented the epicycles in his attempt to corral the planets around the Earth while Copernicus was able to propose a much simpler explanation.

Hence the notion of ‘rationalization’.
The most we can do is to honestly put together whatever facts we have at our disposal in our attempt to justify the conclusion we have already reached.
And then to respectfully accept respectfully offered reactions from those around us.

If you think of it, this is how ‘science’ works. Somebody has a hunch, gathers a lot of data, tries to fit them into the hypothesis he had started from and then submits a paper for his peers to review.
If the paper passes that scrutiny it is published – and submitted to even more criticism.
Eventually somebody else has another hunch, which includes, or even completely contradicts, the previous one…

They key words in all this being ‘honestly’ and ‘respectfully’.
Whenever we knowingly alter the facts (fake news, alternative facts,  autism causing vaccines, etc., etc…) to fit our narrative we end up in a huge mess.
Whenever we fail to respectfully examine the work of those around us and reject it before-hand we simply take a different route to the same huge mess.

WWI was the consequence of a stupid game of brinkmanship while the second one had started with a series of blatant lies. During both we had copiously murdered ourselves.

“There is a concept within Western democracies known as “loyal opposition.” It is based on the assumption that, while you may disagree with your opponent when it comes to goals, or even the means necessary to achieve those goals, you do not question your opponent’s basic patriotism or love of country.

My question for both of you: Are you willing to concede that your opponent is a patriotic American whose election does not pose an existential threat to our country?”

“Over at Emory University, political scientist Alan Abramowitz has established that Americans now line up politically according to what they hate, not what they like.

We are 50 years past Loving v. Virginia, the U.S. Supreme Court decision that overturned state bans on interracial marriage. But only three years ago, a Pew Research study found that 30 percent of hard-core conservatives would be “unhappy” if an immediate family member married a Democrat. And nearly a quarter of hard-core liberals felt the same about a family member who wedded a Republican.

We have talked and Twittered and Facebooked our way into this hole. And we will have to talk and Twitter and Facebook our way out of it.”
