Emmanual Kant, after investigation, considered Swedenborg's visions of the spirit world to be veridical. "Swedenborg’s paranormal experiences were publicly tested and found to be veridical by certain credible people. First, in 1761, a princess tested Swedenborg’s supernatural abilities by asking him to communicate with a particular deceased spirit, and a few days later, Swedenborg successfully conveyed a private message from the deceased spirit to the princess, which absolutely convinced her of Swedenborg’s mystical abilities. Kant adds that “[t]he credibility of such a report stunned me”"  This despite the fact that Kant did not view the entire Swedenborgian corpus as grounded and relevant.
