　　Theholdersofsuchadoctrinemust，itissaid，havebeenwithoutthebowelsofcompassion。Ricardo，ascriticsobservewithundeniabletruth，wasaJewandamemberofthestock-exchange。NowJews，inspiteofShylock’sassertions，andcertainlyJewishstockbrokers，arenaturallywithouthumanfeeling。Ifyouprickthem，theyonlybleedbanknotes。Theyarefittedtobecapitalists，whothinkofwagesasaniteminanaccount，andofthelaboureraspartofthetoolsusedinbusiness。Ricardo，however，wasnotameremoney-dealer，norevenawalkingtreatise。Hewasakindly，liberalman，desiroustobe，ashenodoubtbelievedhimselftobe，insympathywiththeleadersofpoliticalandscientificthought，andfullysharingtheiraspirations，Nodoubthe，likehisfriends，wasmoreconspicuousforcoolnessofheadthanforimpulsivephilanthropy。Likethem，hewasonhisguardagainst’sentimentalism’and’vaguegeneralities，’andthoughtthatahastybenevolencewasapttoaggravatetheevilswhichitattacked。
