Among them are the medieval philosopher Rabbi Chasdai Crescas (Ohr Hashem 4:2) and 18th century kabbalist Rabbi Pinchas Eliyahu Horowitz (Sefer HaBris). After presenting his sources, Rabbi Kaplan remarks, "We therefore find the basic thesis of the Sefer HaBris supported by a number of clear-cut statements by our Sages. There may even be other forms of intelligent life in the universe, but such life forms do not have free will, and therefore do not have moral responsibility"—at least in the same sense as human beings.[8] Rabbi Kaplan also cites Judges 5:23 ("Cursed is Meroz..."), about which Rashi, the foremost medieval commentator remarks, "Some say [Meroz] was a planet, and some say [Meroz] was a prominent person who was near the battle area and yet did not come [to intervene]."
