I disagree. I'm an extremely rational and logical person, who must be convinced of everything through solid evidence before I accept it as real. Yet I find wonder in the world all around me. The world contains plenty of material that captures the imagination.
Yes, but as you say, the material captures the imagination, not your sense of logic or rationality. An appeal to a sense of wonder is not an appeal to rational examination, or logical deduction. It is an appeal to the more emotive parts of your being. Your soul if you like.
