lesson is also contained in the Talmudical passage, which begins, “He who considers four things,” etc., and concludes, “He who does not regard the honour of his Creator”; here also is given the advice which we have already mentioned, viz., that man should not rashly engage in speculation with false conceptions, and when he is in doubt about anything, or unable to find a proof for the object of his inquiry, he must not at once abandon, reject and deny it; he must modestly keep back, and from regard to the honour of his Creator, hesitate [from uttering an opinion] and pause. This has already been explained. It was not the object of the Prophets and our Sages in these utterances to close the gate of investigation entirely, and to prevent the mind from comprehending what is within its reach, as is imagined by simple and idle people, whom it suits better to put forth their ignorance and incapacity as wisdom and perfection, and to regard the distinction and wisdom of others as irreligion and imperfection, thus taking darkness for light and light for darkness. The whole object of the Prophets and the Sages was to declare that a limit is set to human reason where it must halt. Do not criticise the words used in this chapter and in others in reference to the mind, for we only intended to give some idea of the subject in view, not to describe the essence of the intellect; for other chapters have been dedicated to this subject. CHAPTER XXXIII You must know that it is very injurious to begin with this branch of philosophy, viz., Metaphysics; or to explain [at first] the sense of the similes occurring in prophecies, and interpret the metaphors which are employed in historical accounts and which abound in the writings of the Prophets. On the contrary, it is necessary to initiate the young and to instruct the less intelligent according to their comprehension; those who appear to be talented and to have capacity for the higher method of study, i.e., that based on proof and on true logical argument, should be gradually advanced towards perfection, either by tuition or by self-instruction. He, however, who begins with Metaphysics, will not only become confused in matters of religion, but will fall into complete infidelity. I compare such a person to an infant fed with wheaten bread, meat and wine; it will undoubtedly die, not because such food is naturally unfit for the human body, but because of the weakness of the child, who is unable to digest the food, and cannot derive benefit from it. The same is the case with the true principles of science. They were presented in enigmas, clad in riddles, and taught by all wise men in the most mysterious way that could be devised, not because they contain some secret evil, or are contrary to the fundamental principles of the Law (as fools think who are only philosophers in their own eyes), but because of the incapacity of man to comprehend them at the beginning of his studies: only slight
