Are you a Galileonist?

Another creationist video found its way into my YouTube feed. Professional-looking gentlemen having a professional-sounding discussion about the absurdity of evolution.

Darwin said this, and Darwin said that. Darwin believed this, and good old Darwin didn’t know that. And how wrong he was! And today’s Darwinists still cling on to this dying theory. How ridiculous is that!

The discussion is drenched with scientific-sounding words. There’re plasmids, endoplasm, centromere, codons, recessive allele, messenger RNA, genetic entropy, ….. These guys know their stuff! The viewer, not burdened with a lot of scientific knowledge, is impressed. It is easy to see where this discourse is heading to: Darwinism is dead, and today’s Darwinists are only flogging a dead horse because they can’t see, or don’t want to see the TRUTH. Darwin’s been dead for such a long time, for goodness’ sake, let’s move on!

Indeed, Charles Darwin published his main idea 166 years ago. That’s a very long time on the scientific timeline. He had no clue about any mechanisms which could explain his theory.

Let’s assume we can bring him back to life into the year 2025. Let’s give him a Biology 101 textbook to read. He would not have the foggiest idea what these guys are talking about. He recognizes a cell, and he understands the meaning of inheritance, but what is a ‘DNA copy error’? What the heck is DNA? And what on earth is a recessive allele??

In the end, he would look up and say, “I was right after all, all living things are related to one another.”

Let’s go back further in history. The year is 1633. Galileo has been hauled before the Chief Inquisitor. He has two choices: renouncing his crazy idea that the earth is moving or face the torture chamber. Galileo was 69 at the time (in itself an achievement in the 17th century), and he had no desire fighting it out with the Inquisition. So, he just lied under oath.

We’ll bring him back to life and bring him up to speed with 21st century astronomy. He would have no clue on what’s going on around him. What is a galaxy? What the hell is a Black Hole. Who is this Isaac Newton fella who thinks he knows more about gravity than me?

In the end he would say, “Well, after all, I was right, the earth is moving!”

Shall we call ourselves ‘Galileonists’, to distinguish ourselves from Flat Earthers and other Geocentrists? ‘Galileans’ doesn’t cut it, that term is already reserved for Jupiter’s largest moons. What about ‘Kopernicans’, or ‘Copernicans’? No, that sounds too ancient, even with the latinising capital ‘C’.

What do you think?

It is true for Me – But is It True (True with a Capital ‘T’)?

At the time of writing (February 2023), the TasteAtlas food website has just released their compilation of the “100 Best Rated Cheeses in the World”. A total of 8 Italian cheeses made it into the top 10. Unsurprisingly, this verdict sent the French cuisine into a meltdown. Sacre bleu! The first French fromage appears in the 13th spot. Camembert lovers will be interested to know that their favourite was ranked 91 out of 100.

This is an obvious example of ‘true for me’, or in this case it is the truth for a group of cheese lovers who shared their preferences on the TasteAtlas website. Nobody seriously believes that Parmigiano Reggiano, which made it to number one, really is the best cheese in the world, not even the cheesemakers in the Italian province of Parma, although you can bet that they will use this ‘fact’ in their marketing campaigns. You can’t blame them for that.

So, it seems that we can’t get to any absolute truth in matters of food tasting. The same will apply to our sense of smell, put to test in any perfume competition. What about our hearing? Physics can tell us why certain chords sound pleasant to our ears, whereas others sound unpleasant, but there is no ranking of musical compositions according to their beauty. At least not one we all agree on. The same goes for moral truth. Torturing of babies is reprehensible. We all agree on this truth, but all the discussions raging on animal cloning, designer babies, euthanasia, death penalty, etc. tell us that there is no universally accepted truth on these topics.

The quest for absolute truth, Truth with a capital ‘T’, has kept philosophers busy for millennia. Probably the best-known example is the French philosopher René Descartes in the 17th century. In his search for absolute certainty he argued that his senses could fool him (as they have done many times in the past), or he may well be dreaming, or some evil spirit might be trying to deceive him. But of one thing he can be absolutely certain about: He exists. He reasoned that because he is thinking, he can conclude that he must exist. In French “Je pense, donc je suis”, or he might have said it in Latin “cogito ergo sum”. Latin manages to express it in three words only. Also note that I used here ‘certainty’ instead of ‘truth’. But that’s ok in this context.

Descartes was one of the so-called Rationalists amongst the philosophers. He was happy to sit in a warm quiet room, in a comfortable chair, and contemplate on how to get to some absolute certainty, just through thinking alone. He set himself a very high bar. Can we get to some absolute truth, despite our frail senses that might deceive us? Yes, thankfully, we can declare certain things as absolutes. But we need to restrict ourselves to the physical world around us. And how do we get to these absolute certainties? It is through science. Science can tell us what is universally true, and what is false. A simple example: we live on a planet going around the sun. The statement ‘the sun goes around the earth’ is false. Philosophers will tell you that science does not give us absolute certainties. We’ll discuss that when we look at scientific facts and scientific theories. But for now, don’t listen to the philosophers. They question everything. That’s their job. Note that there is another discipline which gives us absolute certainty – mathematics. Seven is a prime number, that is an absolute truth. But it doesn’t tell us anything about the physical universe.
