Guibert attributes Eastern heresy to a supposed climate-induced mental agility

Evidence

Apparently, these men, because of the purity of the air and sky in which they are born, as a result of which their bodies are lighter and their intellect consequently more agile, customarily abuse the brilliance of their intelligence with many useless commentaries. Refusing to submit to the authority of their elders or peers, “they searched out evil, and searching they succumbed” [Ps. 63:7]. Out of this came heresies and ominous kinds of different plagues. — John V. Tolan, Saracens, 785 (#corroborates, via linked claim)
