Context

“The depth and tenderness of his wild affections: the quantity of sympathy he had with things,—the quantity of insight he would yet get into the heart of things, the mastery he would yet get over things: this was his hypochondria. The man's misery, as man's misery always does, came of his greatness. Samuel Johnson too is that kind of man. Sorrow-stricken, half-distracted; the wide element of mournful black enveloping him,—wide as the world. It is the character of a prophetic man; a man with his whole soul seeing, and struggling to see.” source
