Not only did he influence the young hegelians and Marx, he continues to influence many philosophers across all kinds of schools and ideologies.
Marx not being there is an implicit moral judgement - if “great” means good in some ethical sense subjective, then OK. But if “great” means impactful or influential, that’s a problem.
Then no Spinoza, Leibniz, Hume, Tocqueville, Watt, Ramón y Cajal, Ford, Schumpeter, Cervantes…
On the latter, not a single mention of literature. Not even Homer. I find this list problematic in an innumerable amount of ways.
