DO DEMONS EXIST? A review of Jewish ideas about demons - from Biblical to modern times

STAY WITH THE DISCUSSION UNTIL THE END WHERE HE QUOTES RAV SOLOVEITCHIK
A demon is an evil spirit, or devil, in the ordinary English usage of the term. This definition is, however, only approximate. In polytheistic religions the line between gods and demons is a shifting one: there are both good demons and gods who do evil. In monotheistic systems, evil spirits may be accepted as servants of the one God, so that demonology is bound up with angelology and theology proper, or they may be elevated to the rank of opponents of God, in which case their status as diabolic powers differs from that of the demons in polytheism. Moreover, in none of the languages of the ancient Near East, including Hebrew, is there any one general term equivalent to English "demon." In general, the notion of a demon in the ancient Near East was of a being less powerful than a god and less endowed with individuality. Whereas the great gods are accorded regular public worship, demons are not; they are dealt with in magic rites in individual cases of human suffering, which is their particular sphere. https://www.jewishvirtuallibrary.org/demons-and-demonology
