you are absolutely right, Nietzsche should be on top.
He says in Thus Spoke Zarathustra: "Who is more godless than I, that I may enjoy his teaching?"
In The Meme Machine Susan Blackmore points out that ideas don't often depend on a lone genius; when a particular synthesis is "ripe", if one person doesn't introduce it, chances are someone else would before too long.
Charles Darwin wasn't the only one to propose evolution by natural selection. Thomas Edison received his light bulb patent a year after Joseph Swan's British patent.
Gosh! this site has wise, wonderful writers and philosophers!
I used to teach Occam's Razor as a part of maintenance class. The problem with complex systems is that people too often automatically think they have to have complex solutions to their problems. WRONG! Is it plugged in (once, believe it or not, it WASN'T!)? Is it turned on? Are the cables all seated?
The simple stuff makes a difference, and William of Occam was smart enough to see that.
Simple solutions are extremely appealing. However, complex problems often require less appealing and more cumbersome complex solutions. "Black and white" judgments make life simple, but certainly not better.
Which is why I taught: Check the SIMPLE STUFF FIRST ... THEN if that doesn't work, break out the more complex models of what might have gone wrong. It's astonishing how frequently this technique works on mechanical or electrical / electronic systems.
On Homo sapiens? Not so much...
"Everything should be kept as simple as possible, but no simpler."
(attributed to Albert Einstein)
True nuff... I imagine.... I have a mechanical LD
Once, my printer wasn't working. I called my son in Denver for advice and the first thing he asked, "Did you put paper in the hopper?" Insulted, I assured him that was not the problem ... it WAS the problem. Occam's Razor makes a difference.
