A critique of Nietzsche, Aristotle, Plato, Hegel, Heidegger, Al-Mutannabi, and the list goes on, shows a great depth of intellectual exploration, which should form the basis upon which humans develop their thhinking as well as their behaviour. Does this exist?
Philosophy "... is not to be envisaged as a straight line, but as a circle returning into itself. ... In development there is an advance, not into the abstract infinite, but returning back into itself." G.W.F. Hegel
The people, you mention, all thought deeply about life, they all had something important to say and there will be more people like them. The closer we look the more we learn about ourselves; the deeper and more complex our thoughts about each other and life we lead, the richer our insights.
You ask "Does this exist?", I think it does, and it is history.
there is no one philosopher who completely thrills me. all were/are flawed. i am not worried about this. i like bits of this, bits of that. not everyone whose philosophy i admire is considered a philosopher. hypatia, spinoza, hannah arendt, wittgenstein and russell were philosophers but what about joanna russ, carl sagan, richard feynman, louis mumford? maybe there is no name for their philosophies because they didn't think they were philosophizing, but i like the way they think/thought. that's a short list, by the way.
