When, therefore, we speak of genius we do not mean an absolute thing which some men have and others have not, but a small scale-turning overweight of a something which we all have but which we cannot either define or apprehend—the quantum which we all have being allowed to go without saying.

Context

“They will also hold that, important as the physical world obviously is, the spiritual world, of which we know little beyond its bare existence, is more important still. Genius i Genius is akin both to madness and inspiration and, as every one is both more or less inspired and more or less mad, every one has more or less genius. When, therefore, we speak of genius we do not mean an absolute thing which some men have and others have not, but a small scale-turning overweight of a something which we all have but which we cannot either define or apprehend—the quantum which we all have being allowed to go without saying. This small excess weight has been defined as a supreme capacity for taking trouble, but he who thus defined it can hardly claim genius in respect of his own definition—his capacity for taking trouble does not seem to have been abnormal.” source
