“Only those are happy who never think or, rather, who only think about life's bare necessities, and to think about such things means not to think at all. True thinking resembles a demon who muddies the spring of life or a sickness which corrupts its roots. To think all the time, to raise questions, to doubt your own destiny, to feel the weariness of living, to be worn out to the point of exhaustion by thoughts and life, to leave behind you, as symbols of your life's drama, a trail of smoke and blood — all this means you are so unhappy that reflection and thinking appear as a curse causing a violent revulsion in you.”

Letter to Anne, Countess of Ossory, (16 August 1776)
A favourite saying of Walpole's, it is repeated in other of his letters, and might be derived from a similar statement attributed to Jean de La Bruyère, though unsourced: "Life is a tragedy for those who feel, and a comedy for those who think". An earlier form occurs in another published letter:
I have often said, and oftener think, that this world is a comedy to those that think, a tragedy to those that feel — a solution of why Democritus laughed and Heraclitus wept.
Letter to Sir Horace Mann (31 December 1769)
Variant: The world is a comedy to those that think; a tragedy to those that feel.
