77 Mythic rogue here . I play assassination and outlaw mainly and have only a very fundamental knowledge of how sub works and plays . Feel free to ask anything . My armory <| sep |> that question is a cringefest <| sep |> I don ' t think there is a Cartesian anxiety . It ' s true that Descartes ended Meditation I by likening his conventional beliefs to a dream sleep from which he dreaded waking to confront the daylight of his skeptical thought experiments , but he soon conquers his experimental skepticism to his own satisfaction . Notwithstanding the mention of dread , his overall style in the first meditation is not one of dread he ' s hopeful about acquiring indubitable knowledge , and he ' s prepared to resign himself calmly to a suspension of judgment if such knowledge can ' t be found . Such a response would be closer to the ataraxia of the ancient skeptics than it would be to anxiety . Contrast this with Camus ' Myth of Sisyphus . There , the skeptical result is taken as a given , and it clashes with the human desire for meaning , producing absurdist anxiety . As for what you call existentialist anxiety , the connection seems to be a force of deception , only acting in the microcosm instead of the macrocosm . In the Cartesian case , it ' s a grand deceiver in the existentialist case , it ' s the individual ' s own psyche .
