You cannot teach a man anything, you can only help him to find it within himself. – Galileo
Actually the Earth is an oblate spheroid; but as it has only a third of one-percent variation from a perfect sphere, to all intents and purposes the Earth is a sphere with a diameter of 7,918 miles. Taking into account the atmosphere, mountains, and ocean’s, this planet is a gigantic billiard-ball coated with the thinnest film of moisture.
In the fourth century Before Christ. the Greek philosopher Aristotle postulated that the Earth was a sphere; based on his own astronomical and other observations. In particular; the stars in the Southern Hemisphere differ from those in the Northern Hemisphere, the shape of the Earth’s shadow as the moon waxes and wanes, and the way a ship slowly disappears over the horizon as it sails away. Aristotle probably based his theories on the earlier work of Pythagoras from the sixth century BC.
Both Pythagoras and Aristotle were ‘proper’ scientists / philosophers in that they would not accept that something was true just because the majority / a lot of people said it was so. A properly educated man goes out and finds the truth, no matter what some may say.
It is the mark of an educated mind to be able to entertain a thought without accepting it. – Aristotle
Pythagoras is credited with the proof of many aspects of geometry, but there is no evidence that he mastered the spherical geometry needed to properly navigate long distances on Earth.
However, by the 16th century enough was known of spherical geometry for the ship Victoria to circumnavigate the Earth between the years 1519 – 1522 under the command of Magellan and then Elcano. With today’s modern technologies an aircraft taking off from anywhere, and flying in any direction, will, without changing course, end up back at the airfield it took off from.
This is only possible because the Earth is a sphere. You cannot circumnavigate a flat Earth.
Many other things we take for granted are only possible because the Earth is a sphere; gravity, long distance travel, satellite navigation, national television, long-distance telephone calls, space travel, night and day, the season’s, oh…. and did I mention gravity?
Why is it then, that some people stubbornly cling to the mistaken belief that the Earth is flat? Leaving aside that there is a fool born every minute, these ‘Flat Earthers’ point to the evidence of their own eyes, the world outside my front door looks flat – therefore the Earth is flat…QED. By that argument I could say that because I have once met a fool, all men are fools – and because I once met a slut, all women are sluts.
(Actually this is a tenable argument known as The Theory of Mediocrity.)
Some say that all men are fools. And that all women are sluts. All I know is that all things are true some of the time, in the same way that a stopped clock is right twice a day.
I am prepared to believe in some Very Strange Things; the interconnectedness of all things, spooky connections between people, extraterrestrial civilisations, that the past, present and all possible futures run concurrently…. But I am not prepared to believe in; the literal truth of the Bible, nor that the Earth is flat.
I am of the opinion that people who truly believe in those two things, (the Bible and a flat Earth), are closed-minded and have never been outside of their own county. But then, I am myself opinionated, judgmental, highly educated, well-travelled, and well-read. I also strive to walk the warrior’s path with sincerity, honesty, humility, and courage – every single damn day. Which makes whom the better person?
We are what we repeatedly do. Excellence, then, is not a temporary act, but a life-long habit. – Aristotle
Outside of my garret’s door is a path. I can walk along that path, and if I go far enough in a straight line, then in a couple of years I will arrive back at the garret again. This is only possible because the Sun, the Moon, and the Earth are Not Fucking Flat.
No matter who wants to argue otherwise.
a clever charlatan can fool some of the people all of the time
