Moses Mendelssohn, one of the leading exponents of the Jewish Enlightenment ("Haskalah"), strongly disagreed with Maimonides' opinion, and instead contended that gentiles which observe the Noahide laws out of ethical, moral, or philosophical reasoning, without believing in the Jewish monotheistic conception of God, retained the status of "Righteous Gentiles" and would still achieve salvation. According to Steven Schwarzschild, Maimonides' position has its source in his adoption of Aristotle's skeptical attitude towards the ability of reason to arrive at moral truths, and "many of the most outstanding spokesmen of Judaism themselves dissented sharply from" this position, which is "individual and certainly somewhat eccentric" in comparison to other Jewish thinkers.
