ייִדישער מחשבֿה אויף ישעיהו 29:14

We have already mentioned that these theories are not opposed to anything taught by our Prophets or by our Sages. Our nation is wise and perfect, as has been declared by the Most High, through Moses, who made us perfect: “Surely this great nation is a wise and understanding people” (Deut. 4:6). But when wicked barbarians have deprived us of our possessions, put an end to our science and literature, and killed our wise men, we have become ignorant; this has been foretold by the prophets, when they pronounced the punishment for our sins: “The wisdom of their wise men shall perish, and the understanding of their prudent men shall be hid” (Isa. 29:14). We are mixed up with other nations; we have learnt their opinions, and followed their ways and acts. The Psalmist, deploring this imitation of the actions of other nations, says, “They were mingled among the nations, and learned their works” (Ps. 106:35). Isaiah likewise complains that the Israelites adopted the opinions of their neighbours, and says, “And they please themselves in the children of strangers” (Isa. 2:6); or, according to the Aramaic version of Jonathan, son of Uzziel, “And they walk in the ways of the nations.” Having been brought up among persons untrained in philosophy, we are inclined to consider these philosophical opinions as foreign to our religion, just as uneducated persons find them foreign to their own notions. But, in fact, it is not so.
