"Mmm," Childermass tones, which could be a confirmation of the other man's words, or it could be a simple acknowledgment that he said them. It's hard to tell with him, really. He leans back against the side of the building where he stands, taking in the other man and the conviction with which he's made such a statement. It suggests that this is personal, although for what reason Childermass cannot say for certain. Not yet, anyway.

"Perhaps so," Childermass replies after a moment. "Although is not such an experience also defined as learning?" He raises an eyebrow. "And if knowledge were harm, there would be far more stupid people in the world, I think. Or far more damaged, for that." He shrugs again. "It is all in the matter of one's perception. Of course, you being a Guardian yourself," he says, revealing he knows exactly who it is that he is talking to, "I have no doubt what perception it is that you have on the matter. Sir."
