^Frederick C. Beiser reviews the commonly held position that Schopenhauer was a transcendental idealist and he rejects it: "Though it is deeply heretical from the standpoint of transcendental idealism, Schopenhauer's objective standpoint involves a form of transcendental realism, i.e. the assumption of the independent reality of the world of experience." (Beiser 2016, p. 40)

^Lennart Svensson, Borderline: A Traditionalist Outlook for Modern Man, Numen Books, 2015, p. 71: "[Schopenhauer] said that 'the world is our conception'. A world without a perceiver would in that case be an impossibility. But we can—he said—gain knowledge about Essential Reality for looking into ourselves, by introspection. ... This is one of many examples of the anthropic principle. The world is there for the sake of man."
