Aquinas Ethicus Quotes

“Happiness itself, being a perfection of the soul, is a good inherent in the soul: but that in which happiness consists, or the object that makes one happy, is something outside the soul.”
― Thomas Aquinas, Aquinas Ethicus

“The alteration of a human law is right exactly so far as the alteration is conducive to the public interest. But the mere change of itself is in some measure prejudicial to that interest, because custom goes a long way towards getting the laws observed, so much so that enactments running counter to common custom, though light in themselves, seem burdensome. Hence, when the law is changed, the binding power of the law is diminished, inasmuch as a custom is set aside.”
― Thomas Aquinas, Aquinas Ethicus
