Magic Systems

In the earlier days of fantasy, magic was often a given nebulous force that accompanied the story. As the years have progressed, people have conjured up increasingly diverse scenarios and put new sets of constraints on their magic. From this there has arisen some sort of rift in the fantasy community between those who prefer a softer or a harder magic system.

Definition of Magic
I think it’s important that we first define magic. To me, magic is anything that is not possible within the bounds of the reader’s physics. Some people who prefer a soft approach to magic will say that anything that takes a more systematic, scientific approach disqualifies it from being magic. I say that whether or not it’s considered magic by the characters in the book is irrelevant to whether or not it’s magical to the reader. Because all of us live in the same world with the same physics, I think it’s safe to talk about the things outside of our laws under the umbrella term “magic”.

A Call for Mystique
Another argument I see a lot is that magic must have an air of mystique, a sense of wonder, a shroud of mystery. These people are conflating their preference with definitional limitation. That would be the same as saying magic must involve mental exertion, runes, ingredients, demons, handheld conduits, flashing lights, dead gods, temperature changes, incantations, exhaustion, sacrifices, or any other number of requirements. Certainly someone can have favorites, but personal penchants do not nullify all other options.

The Basis of Fantasy
The basis of fantasy and all good speculative fiction is that it poses a question and then explores the answers. The question is almost always in the form of, “How would humans react if they were put into a situation where [blank]?” (Possibilities for the blank: the gods interacted with men, dragons roamed the earth, there were other sapient species, certain people could control the weather?)

We live in a world that has figured out electricity and magnetism, wireless data transmission, nuclear power, space travel, DNA modification, vaccines, and endless other marvels. In a world where magic was relatively widespread, it would require great suspension of disbelief to pretend that that world’s humans hadn’t made any investigations into the nature, limits, and uses of that magic.

Now, there are possibilities of regressions, dark ages, and that their discoveries haven’t advanced very far yet. Maybe a god is keeping them from learning too much. Maybe they’re religious and kill anyone who uses magic outside the prescribed methods. Maybe they live in an extremely harsh environment and don’t have any extra time to devote to study. Maybe magic is only available to very few people. There are many good reasons why the world wouldn’t know very much about the limits of their magic. But human ingenuity, curiosity, and persistence are powerful forces, and I believe that wherever possible, they will have made at least some investigations into the strange powers at play in their world.

The Limitations of Constraints
I believe that constraints inspire more creativity than sheer freedom does. You see it in music when a composer decides, for example, to create something in a whole tone scale, never use the key’s base chord in the progression, write in 5/4, or use at least one augmented chord per measure. Working within limitations allows you to push the boundaries; when working with pure freedom there are no boundaries to push.

I hope the above explains why I lean more toward the hard magic end of the spectrum. Let’s take Sanderson’s Mistborn, specifically the steel push and the iron pull. At its core, these two powers are nothing more than telekinesis. However, the constraints that Sanderson places on them turns them into so much more. These include

• Must be a misting (born with the ability to burn a metal in your stomach)
• Must have your metal in your stomach; once out, so are your powers
• Can only push/pull on metals
• Can only push/pull in a straight, radial line from your center of mass
• Every push/pull reacts with a proportionate pull/push on you

So Sanderson took a very common power, telekinesis, put constraints on it, and turned it into something that’s far more interesting. Battles and puzzles require more creativity. I find that often when the magic is less defined I wonder why a particular magical solution wasn’t applied earlier than it was, or why it wasn’t applied again at a later point.

That being said, some people prefer a less systematic approach, just as some people prefer not to listen to music in 5/4 or music that has an augmented chord in every measure. Both opinions are right for those that hold them.

Conclusion
Both hard and soft magic systems are valid, even if you prefer one over the other. I have read, enjoyed, and written both kinds. However, I typically get more enjoyment out of hard systems, so I tend to use those in my bigger series so I can flex my creativity against the constraints.
