『The World as Will and Representation』要約

Arthur Schopenhauer’s *The World as Will and Representation* (1818; expanded 1844) argues that the world we experience is fundamentally idea or representation, structured by the forms of space, time, and causality that belong to the knowing subject. This follows Kant’s distinction between appearance and thing-in-itself, but Schopenhauer identifies the thing-in-itself as will: a blind, striving, insatiable force that objectifies itself in all phenomena. The human body provides the key, since we know it both as representation and, inwardly, as will. The book’s distinctive framework unfolds in four parts. The first examines representation and the principle of sufficient reason. The second focuses on the will as the inner essence of nature, from inorganic forces to plants, animals, and human striving. The third treats the Platonic Ideas and aesthetic experience, especially music and the visual arts, as temporary escape from willing. The fourth addresses ethics, suffering, and the denial of the will, culminating in asceticism and resignation. Schopenhauer claims that life is dominated by endless desire and boredom, so satisfaction is fleeting. His pessimism, theory of the will, and idea of will-less contemplation influenced Nietzsche, Wagner, Freud, and later existential thought. The work remains a foundational text of German idealism’s aftermath and philosophical pessimism.
