A proportionate good corresponds to every evil (otherwise, evil would not be a privation.)
Some evil is infinite (i.e. because it contradicts an unlimited good)
Some good is infinite.
The minor premise is the key one, but it arises by definition, since any unconditioned good defines what is contrary to it as an infinite evil: Charity in catholicism, for example, is an infinite good and what destroys charity causes an infinite evil; but overcoming oppression is the same sort of infinite good in Socialism, as is the preservation of the planet in (some forms of) environmentalism, or freedom in Libertarianism, etc. If a Catholic finds what contradicts charity, a socialist what contradicts overcoming oppression, etc. they have found the evil that must be resisted at all costs, but anything that must be resisted at all costs is an infinite evil, which in turn opens the possibilities of infinite violence – the only question is on whom and by whom it will be exercised.
In the face of this, there is a temptation to do away with anything unconditioned, and posit a moral skepticism that sees all claims as true up to a point, but which must be cast out when they contradict “moral intuitions”. And so the argument goes that the wars of religion prove that Catholicism was (at best) a conditioned good; as the gulags prove the same about communism. The willingness to sacrifice persons to the planet is in turn what proves environmentalism is only true up to a point, and any vaccine mandate proves the same thing for libertarianism.
The most popular argument for this moral skepticism is the reductio ad religionem or the decrying of some belief as “a religion.” As soon as we recognize that, say, environmentalism has absolute commitments defining some beliefs as unconditioned evils, we say that it is not based on “science” or “evidence” but is “a religion.” The argument of course defines science and evidence as the sorts of things never commit us to defining some things as unconditioned evils, and so can never lead to violence. So long as we follow evidence, all shall be well, and all manner of things shall be well. This of course just sets up science and evidence as the unconditioned good, and so, by its own terms, just another “religion.”
I’m fine if we want to define the word “religion” as “the bad unconditioned” and “science” or “evidence” as “the good unconditioned” but this only makes both terms labels in search of something to be stuck on. Karl Marx could define communism as “science” (he did, in fact) and Thomas Aquinas could define the logical deductions of the dogmatic definitions of the Catholic Church as “science” (ditto.)
Humans need unconditioned goods, and these are, in some ways but not all, beyond “evidence” or “science,” not because they are irrational, but because they are the first measures of true and false in the practical order. If something accords with these unconditioned beliefs, it is true, even if it looks absolutely bizarre or crazy. In fact, far from disproving the unconditioned, the performance of the bizarre or crazy more proves one’s dedication to it. The unconditioned has a logic pressing it to the extreme: the monk doing six lents a year, the revolutionary in the throes of the festival of reason, the climate activist advocating to classify ecocide as an international crime, the socialist who sees oppression and racism everywhere, the rationalist believing that St. Thomas’s arguments are sufficiently refuted by noting the year he died, the believer in biblical inspiration saying there are no errors in the Bible, the imperialist believing that subjugation is for the good of the subjugated, etc. From outside the unconditioned good, all of these are crazy; from within it they are all rational and necessary.
I’m Thomist so my unconditioned goods should be manifest. I fully confess that they are above human reason, comparable to how the rationality of the K9 trainer is above the German Shepard or the rationality of the teacher is above the first-grader. The value of my system – and here I mean most generally theism-with-revelation – is that it allows for there to be goods above human reason that we can nevertheless pursue as rational, specifically things known to be true by God and the blessed, and shared with us that we might participate in divinity.
