Good and Evil (part 1)

Many of my students seem to think that the existence of goodness is somehow dependent on the existence of evil. They have vague intuitions, that is, that the existence of evil is somehow necessary for the existence of good. Call this the “Metaphysical Necessity View” (MNV). Students often employ this sentiment, or something akin to it, in their attempts to defend God against the charge that the existence of evil (or evil of certain sorts, degrees, or amounts) is logically inconsistent with the existence of God (or at least casts considerable doubt on the idea that God exists). I think these students are wrong: they are wrong both about good and evil and to try to defend the existence of God on such grounds. Another, much more plausible, view lurking in the neighborhood of MNV is what I’ll call the “Epistemic Necessity View” (ENV). This position concerns not the existence of good and evil but knowledge of the existence of good and evil. According to ENV, it is impossible (for humans anyway) to have knowledge of the good without having knowledge of evil too. This position, as I say, strikes me as much more plausible than MNV, though it too seems to me to be mistaken.

The following are some vague thoughts of my own on the matter. My hope is that in the process of writing out these thoughts my (and perhaps even your) understanding of these issues will begin to sharpen.

For this blog, let’s deal with MNV. The advocate of MNV suggests that goodness and evil somehow need each other. Statements like this often contain some offhand remarks about “yin and yang,” though, as of yet, no one has explained to me how that is supposed to help. So, do good and evil need each other? Are they somehow mutually dependent? I don’t know of any good reason to side with mutual dependence folks here. In fact, it seems to me that MNV is among the least plausible theories of good and evil on offer – though perhaps not quite as bad as the “explanation” that good and evil do not exist at all but rather are, say, social constructions or mere subjective feelings about things that have no real connection to the world an sich (“in itself”).

One promising way to criticize MNV is to think about its implications, chief among them that if MNV is true, then it is impossible for there to be a world that is purely good, a world where good exists and evil does not. Is it really impossible for there to be such a world? It doesn’t seem so, at least not to me. Indeed, I have a strong intuition that it is possible for there to be a purely good world. But if there is such a possibility, then MNV is false. It’s an easy argument.

  1. If MNV is true, then it is impossible for there to be a purely good world
  2. It is possible for there to be a purely good world
  3. Hence, MNV is false

I see no reason to reject number 2 except that it conflicts with MNV, but to use MNV as a premise in an argument for MNV is clearly question begging, so that won’t do. What other reason might one give for the impossibility of a purely good world? ...I can’t think of any. (Can you? If so, please share!) So I think it’s reasonable to assume that MNV is false.

(Moreover, if one is a theist – especially a Jewish or Christian theist – then one has another powerful reason to reject MNV: “And God saw everything that he had made, and behold, it was very good” [Genesis 1:31]. I’d say that pretty much rules out MNV too. Of course, quoting Scripture probably won't satisfy the agnostic inquirer, but it certainly carries a lot of weight with believers. And why prefer the evidential standards of one who admits to not knowing [cf. agnostic] to the standards of one who thinks she does?)

So much then for MNV…See a future post for a discussion of ENV.
