religious motive, is in danger of falling into gross materialism. For what else is the meaning of such declarations as “Believe what you like, but conform to this or that mode of life”; what else does it mean but “We cannot expect you to believe that the things you are bidden to do are commanded by a higher authority; there is not such a thing as belief, but you ought to do them for conventionalism or for your own convenience.” But both these motives—the good opinion of our neighbours, as well as our bodily health—have nothing to do with our nobler and higher sentiments, and degrade Judaism to a matter of expediency or diplomacy. Indeed, things have advanced so far that well‐meaning but ill‐advised writers even think to render a service to Judaism by declaring it to be a kind of enlightened Hedonism, or rather a moderate Epicureanism. I have no intention of here answering the question, What is Judaism? This question is not less perplexing than the problem, What is God’s world? Judaism is also a great Infinite, composed of as many endless Units, the Jews. And these Unit‐Jews have been, and are still, scattered through all the world, and have passed under an immensity of influences, good and bad. If so, how can we give an exact definition of the Infinite, called Judaism? But if there is anything sure, it is that the highest motives which worked through the history of Judaism are the strong belief in God and the unshaken confidence that at last this God, the God of Israel, will be the God of the whole world; or, in other words, Faith and Hope are the two most prominent characteristics of Judaism. In the following pages I shall try to give a short account of the manner in which these two principles of Judaism found expression, from the earliest times down to the age of Mendelssohn; that is, to present an outline of the history of Jewish Dogmas. First, a few observations on the position of the Bible and the Talmud in relation to our theme. Insufficient and poor as they may be in proportion to the importance of these two fundamental documents of Judaism, these remarks may nevertheless suggest a connecting link between the teachings of Jewish antiquity and those of Maimonides and his successors. I begin with the Scriptures. The Bible itself hardly contains a command bidding us _to believe_. We are hardly ordered, _e.g._, to believe in the existence of God. I say hardly, but I do not altogether deny the existence of such a command. It is true that we do not find in the Scripture such words as: “You are commanded to believe in the existence of God.” Nor is any punishment assigned as awaiting him who denies it. Notwithstanding these facts, many Jewish authorities—among them such important men as Maimonides, R. Judah Hallevi, Nachmanides—perceive, in the first words of the Ten Commandments, “I am the Lord thy God,” the command to believe in His existence.(109)
