Devil
In Osamu Dazai's No Longer Human, the Devil is not a literal entity but a recurring psychological and aesthetic concept that shapes Yozo's perception of human beings and his own artistic identity. It represents the hidden, monstrous core of human nature that Yozo both fears and is compelled to depict, standing in stark opposition to the fragile, trusting innocence he sometimes glimpses in others. The Devil is the dark double of the angel the epilogue will call him, the name for the terror that drives his life of shame.
The Devil as the Hidden Truth of Human Nature
From childhood, Yozo is haunted by the conviction that human beings conceal a monstrous true nature beneath a placid surface. He describes the face of a person raging at him as "a wild animal in its true colors, one more horrible than any lion, crocodile or dragon," and he sees anger as the moment when human nature reveals itself "in all its horror." This revelation is so terrifying that he comes close to despairing of himself, believing that this hidden ferocity might be a prerequisite for survival as a human being. The Devil, for Yozo, is the name for this inescapable, predatory reality that lurks within every person, including himself.
The Devil as Artistic Subject and Kindred Spirit
Yozo's understanding of the Devil is profoundly shaped by his encounter with art. When his schoolmate Takeichi shows him a reproduction of van Gogh's self-portrait and calls it "a picture of a ghost," Yozo is startled into a new artistic vision. He realizes that certain painters, after "repeated wounds and intimidations at the hands of the apparitions called human beings," have come to "plainly saw monsters in broad daylight, in the midst of nature" and dared to "paint pictures of devils." Yozo recognizes these artists as his future friends and declares, "I'm going to paint too. I'm going to paint pictures of ghosts and devils and horses out of hell." The Devil thus becomes the legitimate subject of his most sincere artistic ambition, the opposite of the pretty, conventional pictures he produces for others. His secret self-portraits, which he calls "ghost pictures," are so heart-rending that they stupefy even himself, and he hides them in the back of his cupboard, afraid that others will either detect his true nature or mistake his sincerity for another joke.
The Devil in Contrast to Innocence and Trust
The Devil also functions as a conceptual opposite to the qualities Yozo most admires and fears to lose. When he decides to marry Yoshiko, he is captivated by her "uncorrupted virginity," which he had previously dismissed as a sentimental illusion. He thinks of her trustfulness as "clean and pure, like a waterfall among green leaves." But after Yoshiko is violated, Yozo's faith in this purity is shattered. He comes to see her defilement not merely as a physical act but as the corruption of her immaculate trust, and he begins to doubt whether trustfulness itself might be a sin. The Devil, in this context, is the force that destroys innocence, the knowledge that makes the waterfall muddy. Yozo's own inability to trust, his "cracked and broken" capacity for faith, is the mark the Devil has left on him.
The Devil as the Source of Unending Suffering
In the final stages of his decline, Yozo's life becomes a kind of hell on earth. He becomes addicted to morphine, and his existence is a cycle of debt, shame, and desperate craving. He thinks, "I want to die. I want to die more than ever before. There's no chance now of a recovery. No matter what sort of thing I do, no matter what I do, it's sure to be a failure, just a final coating applied to my shame." He describes his state as "Inferno." The Devil is no longer an external monster or an artistic subject; it has become the very structure of his life, a relentless accumulation of humiliation and suffering from which he sees no escape. Even his final retreat to a seaside village brings no peace, only a numb acceptance that "everything passes." The Devil, in the end, is the name for the inescapable hell of being Yozo.
