The voice of America has no undertones or overtones in it. It repeats its optimistic catchwords in a tireless monologue that has the slightly metallic sound of a gramophone.
— Vance Palmer

Every civilization when it loses its inner vision and its cleaner energy, falls into a new sort of sordidness, more vast and more stupendous than the old savage sort. An Augean stable of metallic filth.
D. H. Lawrence metallic quote

Lying is not only excusable; it is not only innocent; it is, above all, necessary and unavoidable. Without the ameliorations that it offers, life would become a mere syllogism and hence too metallic to be borne.
— H. L. Mencken

Something of vengeance I had tasted for the first time; as aromatic wine it seemed, on swallowing, warm and racy: its after-flavour, metallic and corroding, gave me a sensation as if I had been poisoned.
— Charlotte Bronte

Woman is the future of man. That means that the world which was once formed in man's image will now be transformed to the image of woman. The more technical and mechanical, cold and metallic it becomes, the more it will need the kind of warmth that only the woman can give it. If we want to save the world, we must adapt to the woman, let ourselves be led by the woman, let ourselves be penetrated by the Ewigweiblich, the eternally feminine!
— metallic quotation by Milan Kundera
