My primary object in this work is to explain certain words occurring in the prophetic books. Of these some are homonyms, and of their several meanings the ignorant choose the wrong ones; other terms which are employed in a figurative sense are erroneously taken by such persons in their primary signification. There are also hybrid terms, denoting things which are of the same class from one point of view and of a different class from another. It is not here intended to explain all these expressions to the unlettered or to mere tyros, a previous knowledge of Logic and Natural Philosophy being indispensable, or to those who confine their attention to the study of our holy Law, I mean the study of the canonical law alone; for the true knowledge of the Torah is the special aim of this and similar works. The object of this treatise is to enlighten a religious man who has been trained to believe in the truth of our holy Law, who conscientiously fulfils his moral and religious duties, and at the same time has been successful in his philosophical studies. Human reason has attracted him to abide within its sphere; and he finds it difficult to accept as correct the teaching based on the literal interpretation of the Law, and especially that which he himself or others derived from those homonymous, metaphorical, or hybrid expressions. Hence he is lost in perplexity and anxiety. If he be guided solely by reason, and renounce his previous views which are based on those expressions, he would consider that he had rejected the fundamental principles of the Law; and even if he retains the opinions which were derived from those expressions, and if, instead of following his reason, he abandon its guidance altogether, it would still appear that his religious convictions had suffered loss and injury. For he would then be left with those errors which give rise to fear and anxiety, constant grief and great perplexity. This work has also a second object in view. It seeks to explain certain obscure figures which occur in the Prophets, and are not distinctly characterized as being figures. Ignorant and superficial readers take them in a literal, not in a figurative sense. Even well informed persons are bewildered if they understand these passages in their literal signification, but they are entirely relieved of their perplexity when we explain the figure, or merely suggest that the terms are figurative. For this reason I have called this book Guide for the Perplexed.
