As amidst several degrees of darkness we may form a judgment of those which are the least thick, and among precipices which are the least deep, so we may search among false religions for those that are most conformable to the welfare of society; for those which, though they have not the effect of leading men to the felicity of another life, may contribute most to their happiness in this.

如同在几种不同程度的黑暗之中，我们可以判断哪种的黑暗程度最小，或者在数个深渊之间，我们也可以判断哪个深度最浅，所以我们可以在众多有错误的宗教当中找到与社会保障最相一致的宗教；就这些宗教而言，虽然它们对于人们的另一个生命不能达至幸福的结果，却对他们此生的快乐意义重大。
