As a toddler, I discovered that atoms are tiny, indivisible particles.

This was helpful, however flawed.

In center faculty, I discovered atoms are made from smaller elements: electrons zipping round a nucleus of protons and neutrons, like planets round a solar.

This was nonetheless flawed, however much less flawed.

In highschool, I discovered electrons don’t transfer in tidy orbits, however buzz in probabilistic clouds, as a result of one thing mumble mumble quantum states.

This was even much less flawed (and if I really understood it, that’d be even higher).

Every step of the best way, I held in thoughts a barely false view, a helpful fib that served the wants of the second. As a math instructor, the method jogs my memory of a Taylor sequence, every successive time period providing a greater approximation of a transcendental perform. However this sort of development is probably higher captured on this verse by architect/mathematician/poet Piet Hien:

The street to knowledge? —Properly, it’s plain
and easy to precise:
Err
and err
and err once more
however much less
and fewer
and fewer.

Generally I’m wondering: does the identical go for ethical progress? Will we get higher and higher and higher, passing by way of numerous levels of wrongness on the street to ethical reality?

Everyone knows the MLK quote: “The arc of the ethical universe is lengthy, but it surely bends in the direction of justice.” Isn’t there a whiff of calculus within the geometry of this picture? Euphemia Lofton Hayes, the primary African-American lady to earn a PhD in arithmetic, made the connection specific:

The idea of a restrict is merely an expression [in] mathematical type of an ever receding aim of perfection for which man yearns and for which he strives, but by no means attains. With every new approximation, he’s merely nearer…

I discover the imaginative and prescient lovely. I’m much less certain about “true.”

It appears to me that historical past walks like a type of unusual birds or lizards, zig-zagging forwards and backwards. I can by no means inform which means it’s headed till it’s already gone there. And so, whereas the previous few centuries have seen an unprecedented enchancment of humanity’s materials circumstances, I’m cautious of generalizing the sample.

Nonetheless, even when a civilization doesn’t progress this manner, maybe a single individual can.

As William James argues in The Ideas of Psychology (1890), people are “gregarious animals,” at all times looking for the approval of others. Alas, this want for approval can lead us astray: “many a person actually nice, many a girl actually fastidious… will take a deal of bother to dazzle some insignificant cad whose persona they heartily despise.”

We battle to tolerate censure, even the censure of idiots. Our social instrument is strung so tight, the least disturbance leaves us resonating for days.

However every of us additionally possesses a religious self: “a kind of innermost middle inside the circle, of sanctuary inside the citadel.” These two selves current a kind of puzzle, a contradiction to reconcile. How can the gregarious animal escape its lust for standing, cease dazzling the cads, and begin cultivating its soul?

James presents a easy method:

When for motives of honor and conscience I courageous the condemnation of my circle of relatives, membership, and ‘set’… I’m at all times inwardly strengthened in my course… by the considered different and higher doable social judges than these whose verdict goes in opposition to me now… [T]he emotion that beckons me on is indisputably the pursuit of a super social self, of a self that’s at the very least worthy of approving recognition by the best doable judging companion…. This self is the true, the intimate, the last word, the everlasting Me which I search.

To rise above the petty judgments of our neighbors, we retreat into creativeness. We envision higher neighbors.

After which even higher ones.

As our imaginary judges develop extra simply and discerning, our morality grows by corresponding steps.

“All progress within the social Self,” James says, “is the substitution of upper tribunals for decrease.”

We develop by successive approximations.

Is moral progress like a mathematical limit?
