The field of biography is a tricky one, fraught with many perils, the chief of which is falling in love with your subject. The other is coming off as an absolute idiot, either by failing to explain what was going on, by explaining too much, or by explaining in such a fashion as to make your readers doubt your sanity, your literacy, or your mastery of contemporary English.
I am sorry to say that this passage, from Eric Metaxas's Amazing Grace: William Wilberforce and the Heroic Campaign to End Slavery fulfils almost all of them. Since I fear, Gentle Readers, that you will not have any idea of Mr. Metaxas's subject based on what he wrote, allow the Amateur Historian to explain that Mr. Metaxas is describing a carriage ride in the Alps taken by William Wilberforce, he of the great mind and moral character, but diminutive stature, and Isaac Milner, an intellectual and physical giant elected to the Royal Society as an undergraduate at Cambridge. This is copied verbatim.
"The extraordinary felicity of this scene, of these incandescent minds meeting on this subject of eternal things, sailing in their horse-drawn coach through the mountains, seems like something out of a fairy tale, one in which a gnome and a giant on a journey in a sphere of glass and silver discover the Well at the World's End, and drinking a draught therefrom learn the secret meaning at the heart of the universe."
... a gnome? That's just mean.
