Why did Wilhelm Ostwald support the international peace movement?

Wilhelm Ostwald supported the international peace movement because he viewed war as a significant waste of "social energy."

Guided by his philosophy of "energetics," which he expanded to include sociology and ethics, Ostwald adopted the personal imperative: "Do not squander energy—utilize it!" Because he held strong utilitarian views regarding science, he believed that any obstacle to scientific progress constituted a squandering of this social energy. Consequently, he committed himself to the international peace movement—alongside other efforts like the standardization of scientific documentation and the promotion of a universal language—because he considered war to be a destructive force that squandered human and societal potential.1
