"The entire way we teach magic is structured around control," Severus tells him, sat back in his seat. He considers a cigarette. "Using wands and incantations. We can all use magic without it, instinctively, but that raw power is unpredictable and destructive. Training people to use magic only deliberately through deliberate methods is important."

And.. Severus doesn't totally agree with it, which is why he rarely does those things. Sometimes it's very difficult and sometimes he needs to cave to silly wand motions and verbal spells, but he remains affronted about having to. It's one of the reasons he was drawn to potions so much. "Ethics and all that--" he shrugs, picking up the coffin nail box. "We've just been through a war. Societal values was one of the sticking points. I don't know if I have an answer about it."
