When the conclusion doesn’t follow the premise it’s called – stupidity?

It always intrigues me how humans tend to imagine matters of opinion to be empirically true – as if matters of fact – even when they are not.

It’s a cognitive issue, one that I suspect is linked to the way some people validate themselves. And it leads to a logical disconnect, a favourite of the woo-brigade, who confront readers with what they call ‘the evidence’ for their asserted conclusions, as if what they are describing was a simple if-then approach based on empirically provable fact.

What do I mean? Try this. Here is the ‘evidence’:

  1. The island of Elephantine in the middle of the Nile is so-called because it looks like an elephant from above.
  2. The ancient Egyptians couldn’t fly.

And here is the obvious conclusion that has to be drawn from it:

  1. Ancient alien astronauts from Sirius landed on Earth, bred with humans, created the Egyptians, and then took them on flights over Elephantine, which is how it was named.

Did anybody spot the flaw in that logic? Apart from the point that the island doesn’t look like an elephant. Apparently there’s no firm information as to how it got its name, but its role in the elephant tusk trade has always been suspect. Here, let me show you another one, which I saw in a book purporting to describe New Zealand’s secret pre-history. Here’s the ‘evidence’:

  1. The author’s six-year old thinks scratches in a rock face near Mount Tauhara looked like a dinosaur drawing.
  2. The author thought these scratches were made by secret ancient pre-Maori settlers unknown to archaeologists, but who he saw evidence for everywhere.

Leading to this conclusion:

  1. Therefore ancient pre-Maori settlers in New Zealand both existed AND had time travel.

It’s a classic false-premise fallacy, and the problem is the logical disconnect between premise and conclusion – often coupled, as in the Elephantine case, by a total failure of research in the first place (‘I don’t know the answer, therefore nobody can know’). Sometimes what these people call ‘the evidence’ is, itself either opinion or an assertion. And yet those who assert such things believe their logic is impeccable.

All I can put it down to is the habit humans have of believing opinion to be an empirical fact, coupled with our innate ability to find patterns even when none exist. If you assume that the first premise of a logical statement is true, and assume that the ‘operating principle’ you have in mind applies – for instance, that ancient aliens came down to Earth – everything else follows.

The silliness of the conclusion is lost amidst the apparent watertight nature of the logic.

Have you seen examples of this sort of thing? Do share.

  1. Gotta love those ancient aliens. If only they’d left some good recipes behind. Still, I understand the logic. I’ve never seen the guy who lives above me leave his apartment. It took awhile, but I realized he teleports everywhere he goes. What other explanation could there be? 😉

  2. I am having just such an ‘issue’ with the person or persons putting out a press release for Hold the Faith. There are things in it that give a false impression. It is irritating – and I have sent it back with corrections three times. (So much for ‘third time lucky’ LOL)
    Seems that what people THINK might happen, or have happened, is more important than wasting time proving it. As for Elephantine island – well it is more interesting to say ‘aliens took them flying’ – and support the aliens building the pyramids theory.

    I love logic. It can be so malleable at times. For me, the Theory of Evolution is the same way. The theory of Like Begets Like means that humans will have human offspring. I can’t have a giraffe which I’d really like. Yet on the other hand, evolution says that a single cell from the ocean (they don’t say where the ocean or the orb we live on came from) changed into an air-breathing, walking fish, eventually became an ape and finally into a thinking (most of us), emotional human being with a totally different body system than what was found in that single cell. How many times did lightning have to strike to make all those changes? What caused the formation of the animals and plants? A different wattage? When you look at how well balanced everything is, it makes you wonder how evolution managed to get all the changes at the same time. I believe in God and His creation as you may have guessed. Do I have all the answers? No. Do I need all the answers now? No. I’ll wait until I get to heaven to find out. ~ Connie
