My attention was recently drawn to the arguments of English divines, in answer to certain physiological publications tending to materialism, in consequence of the similarity, if not the identity of some of their reasonings, with those which I recollected to have seen in a Persian work, written by a Mohammedan in the thirteenth century. I accordingly sought for the passages, and the following translated extract from the “ Akhlâk è Nàseri” is the result of the search. This striking similarity of reasoning is probably to be attributed to the actual derivation of each from one common source— the works of the Greek philosophers, with which the Persian author evinces an intimate acquaintance.
