with equal instinctiveness, and with a fine perceptive flair which is superior to any reason, every animal shudders mortally at every kind of disturbance and hindrance which obstructs or could obstruct his way to that optimum (it is not his way to happiness of which I am talking, but his way to power, to action, the most powerful action, and in point of fact in many cases his way to unhappiness).
animalia orok, halaber era instintuzkoan, eta "arrazoi ororen gainetik dagoen" usaimen-fintasunez, izulaborria sentitzen du optimumerako bidean tartejarriko zaizkion edo jar lekizkiokeen nahaste eta eragozpen guztien aurrean (-mintzo naizena ez da "zorion"erako bere bideaz, baizik botererako, ekintzarako, egite ahaltsuenerako bideaz, eta, egitez, kasurik gehienetan, zorigaitzerako bere bideaz).
