'Subsequent to his successful manipulation of Hooker and Lyell in 1858, to ensure that Wallace did not get his priority over him, the following year, and just weeks before defending his priority to Baden Powell in 1859, Darwin writes to Hooker on Christmas Day, 1859, to say that he has always strongly felt that no one should defend their priority (Darwin 1859b). Seemingly, this most weird letter is meant to be both appreciative and self-flattering that he manipulated Hooker and Lyell to do so on his behalf, even if that meant unethical conduct on their respective parts. We know that Darwin had a weirdly unethical mindset when it came to scientific priority, but in this case, one might wonder whether perhaps he had started just a tad too early on the mince pies, rum source, sherry and port, or perhaps he was using something stronger? Or perhaps there was simply something far more profoundly wrong with the moral wiring of his mind.'
Darwin was a serial liar who was in fact obsessed with slyly stealing priority from others for his own glorification. Years earlier he started a prolific letter campaign to try to get Royal Society and British Association for Advancement of Science tore-write the rules on priority for discovery changed so that mere replicators like he could claim priority for the prior-published discoveries of lesser known scientists. Those independently verifiable facts are here.
Below, you can see the facts of how Darwin blatantly and clearly lied in order to plagiarise by glory theft Patrick Matthew's original ans prior published conception of macroevolution natural selection.
The peer reviewed facts of Charles Darwin's lies and independently verifiable evidence he committed plagiarism, to effectively claim independent discovery of Matthew's prior-published hypotheses of the process of macro evolution by natural slection, can now be read in learned journals:
