and because I expose therein the absurdity of their perverse notions, which constitute their riches and peculiar treasure, “stored up for their ruin.” God knows that I hesitated very much before writing on the subjects contained in this work, since they are profound mysteries; they are topics which, since the time of our captivity have not been treated by any of our scholars as far as we possess their writings; how then shall I now make a beginning and discuss them? But I rely on two precedents: first, to similar cases our Sages applied the verse, “It is time to do something in honour of the Lord: for they have made void thy law” (Ps. cxix. 126). Secondly, they have said, “Let all thy acts be guided by pure intentions.” On these two principles I relied while composing some parts of this work. Lastly, when I have a difficult subject before me—when I find the road narrow, and can see no other way of teaching a well established truth except by pleasing one intelligent man and displeasing ten thousand fools—I prefer to address myself to the one man, and to take no notice whatever of the condemnation of the multitude; I prefer to extricate that intelligent man from his embarrassment and show him the cause of his perplexity, so that he may attain perfection and be at peace. INTRODUCTORY REMARKS. [On Method.] There are seven causes of inconsistencies and contradictions to be met with in a literary work. The first cause arises from the fact that the author collects the opinions of various men, each differing from the other, but neglects to mention the name of the author of any particular opinion. In such a work contradictions or inconsistencies must occur, since any two statements may belong to two different authors. Second cause: The author holds at first one opinion which he subsequently rejects; in his work, however, both his original and altered views are retained. Third cause: The passages in question are not all to be taken literally; some only are to be understood in their literal sense, while in others figurative language is employed, which includes another meaning besides the literal one: or, in the apparently inconsistent passages, figurative language is employed which, if taken literally, would seem to be contradictories or contraries. Fourth cause: The premises are not identical in both statements, but for certain reasons they are not fully stated in these passages; or two propositions with different subjects which are expressed by the same term without having the difference in meaning pointed out, occur in two passages. The contradiction is therefore only apparent, but there is no contradiction in reality. The fifth cause is traceable to the use of a certain method adopted in teaching and expounding profound problems. Namely, a difficult and obscure theorem must sometimes be mentioned and assumed as known, for the illustration of some elementary and intelligible subject which must be taught beforehand, the commencement being always
