To Begin With
To start let me point out that we live in a world where magick just doesn't work, no matter what some would like. But there was a time when magick was thought to work, a lot of people tried using it, and work was done to put it on a scientific basis.
In fact a lot of the early scientific work consisted of people experimenting with magick in its various form to learn how and why it worked. Only to learn that it didn't, and couldn't. Or, when it seemed to work to learn just what was going on. From these experiments we got such sciences as chemistry from alchemy and astronomy from astrology.
For the Thing is
That in all honesty science is not a thing, it is a set of techniques, a set of procedures designed for the purpose of discovery and investigation. Combustion is a matter of rapid oxidation, not will. Metabolism involves the physical, not the arcane.
And as with science the laws of magick are not prescriptive, they are descriptive. The Law of Similarity applies because that which is like another will affect it. Nothing moral involved. You get right down to it, science can be applied to magick so long as magick does work in the setting. In a fantasy setting that is the case. That means that magick can be understood. That it can be taught, can be learnt, and can be modified. That our understanding of magick, as with our understanding of science, can be improved and what had once been assumed of magick can be falsified. If that makes a wizard sound like a scientist, that's because he is. A bachelor of magick knows everything, a master of magick knows nothing, and to a doctor of magick neither does anybody else.
So know you have some of my thinking on magick and we can continue with our series.
