Oh really? I can show you some threads here on JPP that would prove that proposition wrong. LOL
All I can say is that Roger Waters must have learned how to build a wall from Charles Darwin (one brick at a time). He makes a central thesis statement, then he list the facts that support his thesis, they he list a wide array of examples of empirical observations that support those facts, then he lists the flaws, weaknesses and absence of evidence....and he does it one brick at a time without ever losing focus on his central thesis.
Where anyone else would have gotten lost or buried in phylogenetic history, Darwin starts out with common every day livestock....but he stays on point. Brilliant riding. It's withstood over 150 years of more scrutiny and examination that any other idea proposed by man, and yet it still stands.
What impresses me the most is that Darwin was no genius. He was just a dedicated, hardworking, persevering, completely methodical, competent scientist. He wasn't a genius like Einstein or Newton but his ideas were every bit as profound. So probably the most important thing I learned from reading "On The Origins Of Species" is that great science is 1 part inspiration, 10 parts perspiration and 100 parts preparation. In other words, it takes a whole lot of elbow grease to be good. Genius certainly helps but it's mostly good ole elbow grease.
Good insights.
A good scientist is, above all, a good observer. A keen observer. Someone possessing clarity of mind. Darwin was a natural at observing the world around him, and coming to profound insights through the power of induction.
We have to remember that Einstein himself was a mediocre student, who was stuck at a dead end job in the Swiss patent office. Hardly an auspicious start for any scientist, let alone a world class scientist.
What Einstein had - and Darwin had too - were very creative minds. Free thinking minds. Minds that could think outside the bounds of convention. I mean, what made Einstein famous was not his dexterity at higher math. It was his thought experiments - the insights he reached simply by thinking about the speed of light and relative motion. In hindsight, those were actually fairly simple - but very profound and creative insights.
Well, that's my story, and I'm sticking with it.
