I didnt vote for anyone, IRL. Cant get my head around it! I take your point(s) concerning Aristotle, and I do appreciate his cultural/philosophical impact, but is that such a mark in his favour as you suggest? If our world is so much the inherited sum of his philosophical effects.....look at the state of the bloody world!
And Leibniz...no doubt much overlooked, and all you say about him is true. But perhaps he was just a wee bit too clever? Jayzus, any man who sat around imagining a pre-existent state of warring essences, all in a state of conflict, one with the other, to test their relative existential 'compossibility', to see which sets would earn the right to break into future existence......this poor fella obviously had too little to occupy his mind....and it wandered.
Sorry to shoot down these great men without offering any alternatives. I have a fondness for Einstein, Socrates and more that are not on the list, but there are different types of 'clever'.....
