Does Aikido genuinely have a ethical and philosophical tradition, do aikido people genuinely believe in or work toward an Art of Peace? Probably not.
I think Aikido has both an ethical and philosophical tradition. I also think Aikido has a martial tradition and that the ethical, philosophical and martial traditions are not mutually exclusive. Working one's Aikido toward any specific goal is a personal choice that each practitioner continually refines as the years of practice mount up. So why not a martial art of peace?
