日本語訳お願いします。 ⑧The aggressive part of human nature is not only a necessary safeguard against savage attack. ⑨It is also the basis of intellectual achievement, of the attainment of independence, and even of the proper pride which enables a man to hold his head high among his fellows. ⑩Without the aggressive, active side of his nature, man would be even less able than he is to direct the course of his life or to influence the world around him. ⑪In fact, it is obvious that man could never have attained his present dominance, nor even have survived as a species, unless he possessed a large amount of inborn aggressiveness.
