"And these things* are all lies and deception... it isn't proper for Jews, who are wise and clever, to continue this nonsense and it should never enter their minds that there is an advantage or benefit [to'elet] to using these things... any person who believes in these things and imagines that there is truth and wisdom behind them - though the Torah prohibits them (to Jews) - is from among the fools and the stupid people [scholim u'chasrei daa't] and in the category of [people] who have incomplete mental facilities.
Those who posses authentic wisdom and pure knowledge know through clear proofs that every one of these things that the Torah prohibited is not wisdom, but nothingness and nonsense [tohu v'hevel] that is continued by empty-headed people [chasrei da'at] who have caused the ways of truth to be abandoned.
*In the preceding paragraphs all sorts of magic, witchcraft, sorcery, and superstition are defined; the quote refers to these practices.
