for the existence of God, as I shall demonstrate. Note this. CHAPTER LXXI Know that many branches of science relating to the correct solution of these problems, were once cultivated by our forefathers, but were in the course of time neglected, especially in consequence of the tyranny which barbarous nations exercised over us. Besides, speculative studies were not open to all men, as we have already stated (Introd. p. 2, and I. chap, xxxi.), only the subjects taught in the Scriptures were accessible to all. Even the traditional Law, as you are well aware, was not originally committed to writing, in conformity with the rule to which our nation generally adhered, “Things which I have communicated to you orally, you must not communicate to others in writing.” With reference to the Law, this rule was very opportune; for while it remained in force it averted the evils which happened subsequently, viz., great diversity of opinion, doubts as to the meaning of written words, slips of the pen, dissensions among the people, formation of new sects, and confused notions about practical subjects. The traditional teaching was in fact, according to the words of the Law, entrusted to the Great Tribunal, as we have already stated in our works on the Talmud. (Introd. to Mishneh Torah and Introd. to Commen. on the Mishnah). Care having been taken, for the sake of obviating injurious influences, that the Oral Law should not be recorded in a form accessible to all, it was but natural that no portion of “the secrets of the Law” (i.e., metaphysical problems) would be permitted to be written down or divulged for the use of all men. These secrets, as has been explained, were orally communicated by a few able men to others who were equally distinguished. Hence the principle applied by our teachers, “The secrets of the Law can only be entrusted to him who is a councillor, a cunning artificer, etc.” The natural effect of this practice was that our nation lost the knowledge of those important disciplines. Nothing but a few remarks and allusions are to be found in the Talmud and the Midrashim, like a few kernels enveloped in such a quantity of husk, that the reader is generally occupied with the husk, and forgets that it encloses a kernel.
