The definition of "black"

Sometimes people get so technical in creating definitions that they end up defining or categorizing things in a way that flatly contradicts the colloquial definitions of those things. I think that's lame.

One example is the question of whether black is a color. Some people say that it's not because it's the "absence of color", or it's a "shade", which can be used to modify a "color". 

But, come on. "Color" is a way to describe what frequencies of light come from an object to our eyes, and which of the light receptors in our retinas react to those frequencies. We experience colors as contrasts to other colors - just try and describe how a color looks in any other way. In that sense, black is definitely a color. It's one of the ways our eyes perceive light bouncing off of things. If someone is wearing a black shirt, and you ask them what color it is, they don't go "Oh my gosh there IS no color!" They also don't try to figure out which primary or secondary color is being reflected the most and then say something like "I think it's a profoundly dark green." They say it's black. And even you developed some ultra-Vantablack shirt and there were no light coming off of it at all, zero is a valid value that something can have. But then again, there's never really zero light.

And that brings me to another point. Some people say that nothing is really black, because black means no light and everything reflects a little light (except a black hole I guess). But dude, that is NOT the definition of black. If it were, it would be totally useless. That's like saying nothing is cold because nothing has a temperature of absolute zero. There are plenty of things that we all look at and say are black. That's the definition of black. It's all relative. All colors are relative. There's no use defining a common word in such a way that it can't actually be applied to anything.

Edit: The same principle applies to magenta. If you think the definitionn of "color" is "light frequency", then magenta isn't a color either, because that's just how our brain interprets blue + red. And for that matter, brown isn't in the rainbow either. So either none of these things are colors, or "color" refers to how our brain processes light, and not just the frequency of light we see.

Alcatraz vs the Evil Librarians

One of my kids checked out Alcatraz vs. the Evil Librarians from the library. Brandon Sanderson has written some good stuff, so I figured I'd check it out. The book is hilarious. The plot is fine - it's one of those kid-gets-powers-and-has-to-save-the-world types of things. But what makes it great is the commentary that the narrator gives. It's a very self-aware book, written as a biography after the fact, and it openly mocks various tropes in literature. I don't know if I can even say that much about it here without spoiling the jokes, but I haven't laughed out loud at a book in a long time (well except for What If? by Randall Munroe), and I did that several times here.

Axiom Verge

Any Metroid fan will agree that there aren't enough Metroid-like games in the world. So whenever I hear about one, I want to want to play it. But there's often something that shuts me down, like an icky theme or a super melodramatic premise or tone. Axiom Verge is an indie game (like literally by one guy) that is super popular but does have a weird/dark plot. But a sequel came out and people have been raving, so I gave it another look. The plot isn't sadder than Ori, and the icky factor is actually less than the worst of Super Metroid (although in the latter game you can avoid the worst of it). So I went ahead and got it.

Exploring the world is delightful. The visual and musical tone are very reminiscent of Super Metroid and Zero Mission. The whole experience feels familiar - in the sense that it's weird and alien, but the creatures from Metroid would feel right at home there. The power-ups definitely have Metroid-esque analogs, but they are unique at the same time, and it's fun to be surprised with how they enable you to get past the game's various obstacles.


And just like in Super Metroid, you can get lost and stuck. I got super stuck at one point. It ended up being just a matter of having forgotten about one little spot, but as I explored everywhere, I kept finding optional power-ups. That's a sign of good design, in my opinion. And of course when I finally found the way forward... well then I got stuck again, but after that, it was super satisfying. Another time I wandered all over the world trying to find that next item that would let me progress, only to realize that I already had the ability I needed, but I had never thought to use it in a certain way. And believe it or not, realizing that was a good feeling.

I like the boss battles. They're not super complex, but the bosses look cool, and it's satisfying to figure out what to do. (It's usually much simpler than what I expect going in.)


There's a lot of variety in items to collect. I mentioned the abilities that would correspond to "suit upgrades" for Samus, which are the main source of innovation regarding how you get around the world. But there are also upgrades to health and attack power, that sometimes come in pieces you need to collect a bunch of to equal one upgrade. So there is always a reward for exploring. There are also a lot of different weapons. Verify few are strictly required, but there's a lot of variety in how they work, so you can pick what works for you (or what looks the coolest).

The plot is decent but super confusing. The ending - I don't know if it was trying to lead into a sequel or just to cement the feeling that you don't know what the heck is going on. And of course I could have done without the bits of profanity thrown in, and the icky white remains of the former population. (In Metroid, you're always exploring ruins, but you generally don't actually run into the former inhabitants.) I was also a bit thrown off by this item you can get that allows you to enter codes that supposedly alter reality. One of them is obvious, but it doesn't seem to do anything. In fact, even after finishing the game I have no idea what you're supposed to do with it, or what any of the other codes are.

But that aside, Axiom Verge is the most Metroid-like game this side of an actual Metroid game, and that includes Ori. It is glorious.

A Link to the Past

The Legend of Zelda: A Link to the Past has been one of my favorite games, really since I saw the first screenshot and saw that it was a return to the Zelda 1 style and looked amazing. The SNES graphics create a charming world to explore, and there's so much in it - the game has the most levels of any Zelda game, and it started a lot of the conventions they still use in the top-down games, and even some in Breath of the Wild (like certain switches and the sword spin). And the music is super epic - an orchestrated version of the original theme, and probably the best ending sequence of any game. My only real regret about the game is that I read too much before I first played it, so there were a lot of things I didn't get to discover.

I replayed the game again after not having done so for probably 15 years, and it was really fun. I'm surprised at how many things I didn't remember - I'm still not sure where the last 4 heart pieces are. In order to make it challenging, I decided not to power up the Master Sword or my tunic - after all, the green outfit and blue sword look better than the wonky colors you end up with normally. This worked out pretty well.

Here are some screenshots of my journey, along with some random thoughts. (Some spoilers implied)

This is one of my favorite spots. The trees and river create this nice, tranquil vibe. And you passed below it on the way up and saw the heart, but it was inaccessible at the time, so finding the way in is rewarding. It looks like a great spot for a picnic or something.

The Zora king looks cool, and I like how he calls you "little man".

I want a sign like this.


Drat, turned into a bunny again.

Zelda is very quotable.

See that bombed wall in the Tower of Ganon? I had never figured out how to get to it before. But this time I remembered a puzzle I solved (and felt like a genius!) in the extra dungeon of the GBA version of this game, and it hit me! (There's nothing essential in that room, but still!) I will leave it to the reader to figure it out. And no, there is no invisible floor.

This is me fighting Ganon, with the green tunic and blue sword.

... and proof that I won!

Now, a note about where this game falls in the plot. Nintendo has stuck it in the middle of one of three alleged timelines, but I think that's bunk. And A Link Between Worlds positions itself as a sequel to this game, which is also bunk (in part because the state of the Triforce at the start of that game matches the end of Ocarina of Time [split], not A Link to the Past [joined]).

But in any case, this has to be the last Zelda game. Here's why:



See? After this, the Master Sword is never used again. And Ganon is totally destroyed. The Essence of the Triforce said so. I think that precludes putting any other Zelda game after this in the timeline.

Anyway, even though I wasn't surprised by things very often, this game still ranks in my top five ever. Yay Zelda!

Cyber Shadow

This was a really good game for what it is. It's reminiscent of NES platform fighting games, but it has save points at reasonable places, upgrades to find - the stuff you'd expect in a modern game. It also has better, catchier music than most modern games have. A lot of the bosses are very cool looking. The graphics are intentionally retro, but given that limitation they look good.

On the other hand, it also has a melodramatic plot (although you can ignore that), and toward the end the game just gets a little TOO hard. But to be fair, even when things are really, really hard, MOST of the time it's a matter of figuring out what to do, meaning how to best use your various abilities to make the situation more manageable. So for most of the game, I didn't mind having to restart sections over and over because I felt like I was making progress by thinking things through. But in the rare times when it really does require precision (and in the many times when it seems like that's the only way to win), it does get frustrating. But none of this makes me dislike the game overall. (I paid the $15 pre-order price; the regular price is probably reasonable too if you're into this genre - I don't actually have any nostalgia for the NES ninja games.)

There was also one design bug, which I found quite frustrating. There's this part where you have to climb a set of platforms faster than this spirit monkey thing. The game hints that you can make it easier by sword-bouncing off of these lantern things, but I had this power-up left over from a previous area that made a blade spin around me and destroy stuff. That's great when you're fighting enemies, but this thing destroyed the lanterns before I could approach, so I just had to do the whole thing with very precise jumping. Drove me crazy.

Portal (1&2)

For the Christmas break, I played Portal 1 & 2. I had heard about them since forever, but I never really gave them a lot of thought - I was turned off by the "dark humor" motif, and of course they're not on Nintendo consoles. But Steam works on my laptop and the games were dirt cheap.

They're really fun. For one thing, the computer making fun of your character (who's not a bit fazed by the taunting) is pretty funny. And beyond that, the puzzles are really well designed. They're satisfying, not unreasonable, and they make you feel like an absolute genius whenever you solve one.

The portal gun works exactly like you'd expect - you put a blue portal here, an orange portal there, and they're connected. You can go through them. Other stuff can go through. Momentum is maintained. You can look through and see what you'd expect to see, which is generally the same room but from a different perspective (and maybe yourself, depending on how they're positioned). You can't help but want one. But then, that's how all good sci-fi tech is. Unrealistic, but so clear in its purpose and use that you can easily imagine what you'd do if you had it.

Best quotes: this and this, and my personal favorite.

Dealing with weird stuff in church history

[I wrote this on Election Day 2020 but posted it here later. The original, formatted document is here.]

I should say at the start that I have a strong testimony of the gospel of Jesus Christ, and that Joseph Smith is his prophet. I'm grateful for the peace and perspective the gospel has given me, and the blessings I've received as I have tried to live it. For the most part, the history of the church strengthens my testimony - there have been many miracles that show the hand of God in it, and the church has been a positive influence in the world.

It's also fair to say that some parts of church history aren't great. Some people react to this by just rejecting everything about the church. Others make excuses and may even perpetuate some of the unfortunate cultural issues from the past. I have been thinking lately about how to address the negative aspects of the history, so I figured I'd better write it down. Fair warning - this post is long.


The church has never claimed its leaders were infallible. It's actually very important to be able to see a prophet's role as distinct from their identity as a person, because prophets make mistakes. Sometimes really big ones. We need to be able to see and acknowledge this without it shaking our faith in God, or in the core doctrines of the gospel.

When I was young, I imagined the prophets and apostles as being in direct personal contact with Jesus Christ all the time. He told them what to do, and they just did it. I imagined something similar with local church leaders, except through the Holy Ghost instead of visions. As a missionary and in interactions with church leadership, I have since learned that most of the time God leaves decisions up to us and guides us in subtle ways, many times through other people. Most of the time he is fine with the direction we choose, and will only "warn us off" if we're headed for something immoral. We can get extra direction when we seek it (study, ponder, pray). But very seldom does God give us course-altering direction when we haven't asked for it. This is true even for prophets. God reveals truth "line upon line, here a little and there a little". (See 2 Nephi 28:30, Isaiah 28:30.)

This is important to understand with regard to church history, both ancient and modern. The clear modern example is the racial distinction on the priesthood, which was started a few decades after the church was created and wasn't lifted until 1978. I'll say more about this later, but for now I'll just point out that the church has disavowed all of the attempts at explaining the reasons for it using scripture. In other words, it was a mistake. A big, harmful one. Why didn't God correct it sooner? We don't have a direct answer, but I think a part of the answer has to be that not enough people were prepared to follow the direction to stop being racist. It was only when enough people were willing to follow that direction that the change came. (And yes, that means that racism was a huge problem in the development of the church.) Some might hear this and think "How could Brigham Young have been a prophet if he believed such racist ideas?" One answer could simply be a matter of existential priories: God needed a church with a strong community. There had to be enough members in Utah and worldwide to hold the church together. If too many people left too early, no amount of truth would have preserved the church long-term. But having a lot of people in strong communities was something God could work with, and fine-tune their moral failings bit by bit, as they were ready. In any case, I think separating Brigham Young's character as a man from his role as a prophet is actually liberating from a faith perspective. You can criticize one without throwing away the other.

Here's another example: Moses and Joshua wiped out a lot of people on their way from Egypt to the promised land. The Book of Exodus suggests that God told them to exterminate entire communities - men, women, and children. Really? Or is it possible that Moses received revelation about moving people, and commandments about how they should behave, and misinterpreted some of the "how"? I think it is. One might ask again, "Why wouldn't God stop him from committing genocide?" Well, he needed a group of people that wouldn't sink into idolatry. He needed people who would believe in him and pass on the covenant he had made. He knew he could work on the "love your neighbor" stuff later, so he gave them just enough to establish the basics. They weren't ready for any more than that. This is speculation, but it makes sense to me.

One more quick example before I get back to Brigham Young. A lot of people instrumental in forming the United States were guilty of atrocities. George Washington owned slaves. And without him, we would not have this country in the first place. He was a hypocritical white supremacist. And he did great things, for which we are indebted to him. We can believe both. Thomas Jefferson: same thing. Christopher Columbus: he did even worse things. And he was instrumental in the hands of God in forming a free country, and by extension, in the restoration of the gospel. I'm not saying I would vote for any of these men if they were running for office today, but we can acknowledge the good they did even while condemning their immoral behavior.

In a lot of ways, Brigham Young was the George Washington of the early church. God needed someone with leadership skills, and a vision of how to build a community. Brigham Young drove the creation of industry all over Utah and other places the church created settlements. He negotiated a peaceful situation with the United States and the Native American communities in the area. Without him, that church of refugees probably would not have survived its first fifty years.

He was also profoundly racist. He wasn't as bad as a lot of people in the South - he didn't advocate all of the atrocities committed against slaves. He didn't even own slaves. But he did believe in slavery. He strongly believed that black people were inherently inferior. And, while some might say that it's not fair to judge him against modern morality, his actions don't even stand up to the morality of the church at the time. The Book of Mormon condemns slavery, as does the Doctrine and Covenants. Joseph Smith wanted to abolish slavery. But Brigham Young upheld it.

And then there is polygamy. In some ways this is even weirder than the racism thing - not just because polygamy is messed up, but because the early church had a much easier time backing up the doctrine of polygamy with scripture. But women suffered a lot under the practice. And I'm not going from rumors or anything here - most of what I know about the subject comes from the Church's own publications. It was pretty bad. Did God set it up? Well maybe - the whole thing was wrapped in secrecy at the start, so it's not super clear what Joseph Smith said, or which parts of it were direct revelation from God, versus something that another imperfect man might have misinterpreted. (The section in D&C that mentions it didn't come out until a long time after Joseph Smith was murdered.) But even if we accept the institution as created by revelation, the implementation was not great. Women's rights and wellbeing were not respected as much as they should have been. Again, there were a lot of mortal people running this thing, and we shouldn't be surprised when we learn that they messed it up.

So how should we react? I think there are three important things.

First, I think it's very appropriate to be offended. I am offended. Racism is awful. Slavery is a betrayal of the gospel of Jesus Christ on every level. And hypocrisy makes bad things even worse, maybe because it is so effective at convincing people that they are good. We don't need to make excuses for others' wrong choices. It's okay to be outraged.

Second, we need to have a clear idea of core doctrine versus what I'm going to call "interpreted doctrine", versus practices and policies. (See this talk from General Conference, and this one.) There's a broad spectrum of how directly-from-God the things we believe and do fall into. That's just the nature of living in a mortal world. If we're clear on which things came directly from God, we can hold onto those things without getting thrown off when we realize that a human leader has made a mistake. Or even an atrocity.

And third, once we have that clear distinction about church history, we need to apply it to ourselves. We need to ask ourselves, "What part of my beliefs and practices are susceptible to human weakness? Are there perspectives I have that God would like me to change, if only I'd open myself up to changing?" (See Matthew 19:20)

Sometimes it will be policies that will change. But sometimes the doctrine of the church will be added to or clarified in a way that contradicts what members of the church had come to believe. When black people received the priesthood, a lot of members rejoiced - not just for the blessings of their black brothers and sisters, but because they no longer had to make excuses for a racist policy. They were beyond ready. But other members of the church had a hard time with this. They had been immersed in all of the theological rationalization for the policy. The idea of having a black bishop went against their religious beliefs. Of course, this means these people were racist. But the point is that they sincerely believed that God wanted them to be. At least up until that day. After that day, those who had embraced the racism of the time had a choice to make. Some left the church, or stayed but harbored racism. And others opened their minds and hearts and received a witness from God that white people aren't actually superior. Those people changed, and they're better people now.


I want to point out one more concept that I think is in flux in the church today - in culture, if not in doctrine. This bit will involve a lot of speculation - this comes from me, not the church, and I could be wrong in either direction. But it's something that I think about.

It has to do with how we approach homosexuality. Now, the church is pretty clear on the law of chastity - no sexual intimacy except between married people, and marriage is between a man and a woman (because the essence of marriage is creating an eternal family). Most people and cultures in the world today don't believe in or support that standard. We can live with that. We don't walk around glaring at our heterosexual neighbors and thinking of them as unclean. And we should not do that with homosexual people either. The church certainly does not advocate looking down on other people based on who they're attracted to. But in the culture among church members, there is a stigma attached to being gay.

Growing up, I feel like I was raised with a relatively open-minded view of people. Racism always seemed and felt evil. But gay people? I have to admit that I felt an "ick" factor attached to that idea. Like, the idea of two dudes kissing still feels wrong to me - although I think this has more to do with bias than it does with morality. Not all of this bias comes from church - this is in the whole world. But let's examine the church bit.

Let's say you have two teenagers, a boy and a girl. The boy asks the girl on a date. They see a movie and eat food, and the boy pays. They hold hands. At the end of the night he kisses her on the cheek, and then they part ways. Nobody would call that a violation of chastity. Why? Because it's not sexual. It's just feelings, and social interaction. But if you change that story and replace the girl with a boy, all of a sudden you've got a problem. If these are BYU students instead of teenagers, you have an Honor Code violation. Why? If the law of chastity is about sexuality, and sexuality is only okay between a married couple, and romantic behavior is okay outside of marriage, then why are we concerned with non-sexual behavior between two men or two women? Why do we even care?

Of course, the perceived problem is that romantic behavior between people of the same gender "gives expression" to feelings that could lead people to break the law of chastity or to make other decisions that will stop eternal progression. That feels super weak to me. For one thing, two dudes on a date are no more likely to break the law of chastity than a heterosexual couple. The hormones are the same; it's just who they're targeting that's different. And if you're not attracted to the opposite gender, then you're not going to get married to them, so a same-gender relationship isn't competing with a potential opposite-gender one. (I mean if you're bisexual, then maybe it is, but that feels like a technicality that doesn't really sway the argument here.)

So the conclusion that I draw is that we should chill out and get off the backs of gay people. We should try really hard to stop feeling that "ick" factor, and acknowledge that it comes from the societal messaging we were raised with, not from God.

"But, But…" that biased voice in my head says, "how does being gay fit into the Plan of Salvation? What happens in the Celestial Kingdom?" To be honest, I do not know the answer to this. Growing up, my impression was that being gay was a birth defect, so it would be "cured" in the resurrection. That is an awfully insulting position to take. That doesn’t make it untrue, but then there isn't any scriptural evidence to back it up, either. Perhaps Brigham Young might have said that gay people are the way they are because of some spiritual deficiency, like he felt about black people. Of course that is even more insulting, and it feels deeply wrong on a spiritual level. I'd have a hard time even respecting someone who claimed that. The only other answer I can think of is that there's a celestial path for gay people, but it hasn't been revealed yet. Why not? Well maybe it's because the church isn't ready for that revelation. Because we have too much bigotry in the membership. Again. Still.

And if that's the case, then we are just like the members back in 1978 before President Kimball removed the restriction on the priesthood. We have a choice. We can hold onto the traditions of the past and be total jerks to our neighbors, damaging the image of the church and causing our descendants to be ashamed of us. Or we can be ready. We can move past the biases we've been fed and do a better job of thinking of everybody as equals. Neighbors. You know, the way Jesus Christ commands us to treat everybody.
