Lol how dare you answer the question without 'a' or 'b' Brysing. Next you'll explain how magick isn't black or white. For shame.
D, it's an interesting topic, but magick isn't as simple as 'a' or 'b', 'black' or 'white', 'high' or 'low'. Magick can be defined many different ways. I see magick as a science, and in ancient times our ancestors who knew chamomile could cure a cold was called a witch and the tea became a health potion. Today, you can buy chamomile tea at any cafe and most who use chamomile instead of cough syrup is typically seen as 'hippies' or 'new age'.
Magick is also nature as well as energy. Someone could see the change of seasons as 'magickal' and those who cast spells know you much focus energy to cast a spell correctly.
As Time goes on and more advances in science happen, magick does not go away, it changes, our perspective and understanding grows. Perhaps science can tap into the energy casters use, or we discover weather spells are somehow possible, you never know. As it stands science comes from magick [I've read many scientists and doctors are pagan] so magick will never fade away.
