"Judaism boasts no exclusive revelation of eternal truths that are indispensable to salvation, of no revealed religion in the sense in which that term is usually understood. Revealed religion is one thing, revealed legislation, another. The voice which let itself be heard on Sinai on that great day did not proclaim, 'I am the Eternal, your God, the necessary, independent being, omnipotent and omniscient, that recompenses men in a future life according to their deeds.' This is the universal religion of mankind, not Judaism; and the universal religion of mankind, without which men are neither virtuous nor capable of felicity was not to be revealed there... Among all the prescriptions and ordinances of the Mosaic law, there is not a single one which says: You shall believe or not believe. They all say: You shall do or not do. Faith is not commanded, ofr it accepts no other commands than those that come to it by way of conviction. All the commandments of the divine law are addressed to man's will, to his power to act. In fact, the word in the original language that is usually translated as faith actually means, in most cases, trust, confidence, and firm reliance on pledge and promise... Commandment and prohibition, reward and punishment are only for actions, acts of commission and omission which are subject to a man's will and which are guided by ideas of good and evil and, therefore, also by hope and fear. Belief and doubt, assent and opposition, on the other hand, are not determined by our faculty of desire, by our wishes and longings, or by fear and hope, but by our knowledge of truth and untruth. Hence, ancient Judaism has no symbolic books, no articles of faith. No one has to swear to symbols or subscribe, by oath, to certain articles of faith. Indeed, we have no conception at all of what are called religious oaths; and according to the spirit of true Judaism, we must hold them to be inadmissable. Maimonides was the first to conceive of the idea of reducing the religion of his fathers to a certain number of principles, in order that, as he explains, religions, like all other sciences, would have its fundamental conceptions, from which all the others are deduced...Thank God, they have not yet been forged into shackles of faith... In truth, everything depends here also on the distinction between believing and knowing, between religious doctrines and religious commandments. To be sure, all human knowledge can be reduced to a few, fundamental concepts, which are laid down as the bases. The fewer these are, the more firmly the structure will stand. But laws cannot be abridged. In them everything is fundamental; and in this regard we may rightly say: to us, all words of Scripture, all of God's commandments and prohibitions are fundamental. Should you, nevertheless, want to obtain their quintessence, listen to how that great teacher of the nation, Hillel the Elder, who lived before the destruction of the second Temple, conducted himself in this matter. A heathen said: 'Rabbi, teach me the entire law while I am standing on one foot!' Shammai, whom he had previously approached with the same unreasonable request, had dismissed him contemptuously; but Hillel, renowned for his imperturbable composure and gentleness, said: 'Son, love thy neighbor as thyself. This is the text of the law; all the rest is commentary. Now go and study!"
-Moses Mendelssohn, a leader of the Jewish enlightenment, Jerusalem, 1783, trans. Allan Arkush, pp. 97-102
Above is Mendelssohn's explanation of Judaism, as a religion of both reason and commandments. Mendelssohn was a Jewish enlightenment thinker who campaigned for equality for Jews in Europe as well as urging the Jewish community to embrace modern science and rationalist philosophy.
