Submission to a weak man is discipline. Submission to a strong man is only servility.

Context

“(as Carlyle fancied) obeying the strongest and wisest man. On the contrary, the military spirit means, if anything, obeying the weakest and stupidest man, obeying him merely because he is a man, and not a thousand men. Submission to a weak man is discipline. Submission to a strong man is only servility. Now it can be easily shown that the thing we call aristocracy in Europe is not in its origin and spirit an aristocracy at all. It is not a system of spiritual degrees and distinctions like, for example, the caste system of India, or even like the old Greek distinction between free men and slaves.” source
