That's funny because a system that kept a civilization together for 1000 years is being claimed to have "no value" by someone who has no idea how to keep any society together and is mimicking the conventional wisdom of those overseeing a disintegrating society as a result of this ignorance.
Not only does the work of Aquinas have value, it has more value over the long run than anything being produced today, as no ethical system that we hold dear has a chance of keeping anything going for even three generations, let alone 100. Modern society is suffering from collapsing birthrates and social disintegration at an alarming rate, and we are pretending to be smarter than those who set the rules of a civilization that was far more stable and productive than our own, with far more profound accomplishments.
