 Boyle also noted, as did his contemporary Henry More, the Cambridge Platonist, the occurrence of ecstasies. Boyle, like More, took the existence of ecstasies seriously and, accepting the literal meaning of the term, thought that such experiences showed the actuality of non-corporeal, out-of-body, experiences. Boyle indeed offers the case as a refutation of the Aristotelian view that images are required for human thinking. Locke was more cautious on the issue: “whether that, which we call Extasy, be not dreaming with the Eyes open, I leave to be  examined.”[53]
