"The law of the survival of the fittest led inevitably to the survival and predominance of the men who were effective in war and who loved it because they were effective"
About this Quote
The bite is in the coupling of competence and desire. Root isn’t just worried about “men effective in war”; he’s worried about the psychological feedback loop that turns effectiveness into appetite. Loving war “because they were effective” suggests addiction, not ideology: success produces pleasure, pleasure produces repetition, repetition produces political power. That’s the subtext of “predominance” - the warriors don’t merely survive; they rise to leadership, set norms, and tilt institutions toward the conditions that validate them.
Context matters. Root, a lawyer-statesman of the Progressive Era who helped professionalize the U.S. military and advocated international arbitration, was steeped in debates about empire, preparedness, and the first waves of globalized conflict. His warning reads like an argument for constraining incentives: if you want fewer war-lovers in charge, you can’t let war be the fastest route to glory, authority, or social permission. The sentence is a critique of cultures that mistake martial success for civic fitness - and then act surprised when the most practiced fighters start writing the rules.
