Incidentally, as it were, I find it appropriate to remind and warn all authors of their obligation to explicitly cite their sources, and to not appropriate the respect that is due to Torah scholars. Others before me have gone to great lengths in denigrating those who neglect crediting their sources, and go about furtively speaking of ideas and conceptions as though they conceived of them themselves. On this matter, the author of Sha'ar Asher, of blessed memory, wrote that one who so acts robs both the living and the deceased. Such a person robs the living because he could have brought about the Redemption, since it says, "Whoever declares something in the name of its originator brings Redemption to the world"; such a person robs the deceased as well, for mentioning their names makes their lips stir in their grave… These two sayings should suffice for anyone whose heart has been touched by the awe of God. There is, in addition to the obligation to cite one's sources that we mentioned, great privilege to be gained, for this results in positive regard and a good recommendation [for the World-to-Come] because the pleasure it causes above stirs the compassion of Heaven.
