Metaphysics is the branch of philosophy that deals with the first beginnings of reality - abstract principles such as time, identity, being, space - and of course; magic. When we look into the metaphysics of magic, we are essentially searching for the properties of magic, how and why magic is what it is.
Many scholars and wizarding philosophers have attempted to define the parameters of magic and what constitutes as magic, but the goal in our treatise is far more meaningful than that. We wish to explore the essential fabric of magical being, and analyse it under a close eye. There is debate within the wizarding philosophical community, as to whether magic is an art or a science. The older school of thought believed magic to be an art form; with any magical agent being (for the sake of analogy) and artist. Now, as one knows, art is skill, and it requires some natural predisposition for the artist to consider herself one. In laymans terms, artists are born, not made. This, for the philosophers translated into magic. However, as years went on, a recent study presented the case that magic was more of a science - there was a precision to it, it had an alteration to the fabric of reality as we know it - a truly compelling argument. Both arguments however, discredited each other; which is where the flaw in defining magic occurs. I posit, that magic is both an art, and a science.
Let us look deep into the roots of magic, as a concept. The sheer nature of it resembles some sort of force; in physics, a force is something that causes a change in the motion of an object. Arguably, magic is a supernatural force that causes changes within the fabric of reality. I would argue that it does so in the simplest, yet most complex ways. For example; if an agent was to cast a bluebells flame spell, she would essentially be warping the fabric of reality around her to create this flame, which, acting as real flames would, emits heat, and can be felt, seen, smelt or even heard. This, in essence provides us with enough evidence that there is an element of science within magic. However, science is defined as the study of the laws that govern the natural and physical world: so by definition it is reductive to note magic as a form of science; which is where the concept of magic as an art form comes into play.
If we look at any art form; we can see that all of them require a certain talent, that can not be replicated through practice. It can be refined, and smoothed with practice, but an artist generally has the natural ability to transfer her emotion and talent into a canvas. The analogy works the same with magic. The agent is able to harness her emotion, and use it to create a supernatural force; magic. Look at the wideley esteemed patronus charm; it is the caster's emotion of her happiest memory, manifesting itself into a magical force. What can be seen here is an amalgamation of both scientific structure and raw, emotional prowess working together to create an alteration within the fabric of reality as we know it.
With that being said, we have one last metaphysical question on the nature of magic - where did it come from, and how did it spread? The answer, I'm firmly convinced, can be observed through simple biology - genetics. It occurs to me that magic is just like any other biologically inherited trait. For example, if one has blonde hair, we may make the assumption that at least one, if not both of her parents are carriers of the blue-eyed allele. We can argue that magic spreads similarly, except it is a dominant allele within our chromosomes - two magical agents will produce a magical child. Similarly, the child of one magical agent and one nonmagical agent will also inherit her magical parent's ability. But like all genetics, mutations occur and hence we see nonmagical offspring from magical parents, and vice versa. Thus showing the origin and spread of magic.
