Yet for attacking that which is hard and strong nothing can surpass it. I have always felt that air was also deceptively weak. When we think of power tools, many pneumatic items would fall in that category. However, there's no logical reason why submission can't stem from weakness as much as anything else. But then it is no longer submissiveness.
Weakness propagates itself.
I think what makes a strong submissive are the same qualities that make a strong person in general. Strength comes from the confidence to deal with whatever comes at you. That strength can come from family, experience, a quick mind, determination, money, good friends. I am beginning to wonder if what makes a person submissive is perhaps somewhat inherent. However, there's no logical reason why submission can't stem from weakness as much as anything else.
