“Any writer of any worth at all hopes to play only a pocket-torch of light — and rarely, through genius, a sudden flambeau — into the bloody yet beautiful labyrinth of human experience, of being.”

Three Times Three (1936)

The Principles of Success in Literature (1865)
Context: Genius is rarely able to give any account of its own processes. But those who have had ample opportunities of intimately knowing the growth of works in the minds of artists, will bear me out in saying that a vivid memory supplies the elements from a thousand different sources, most of which are quite beyond the power of localisation, the experience of yesterday being strangely intermingled with the dim suggestions of early years, the tones heard in childhood sounding through the diapason of sorrowing maturity; and all these kaleidoscopic fragments are recomposed into images that seem to have a corresponding reality of their own.

Context: You can never be too cautious in your prognosis, in the view of the great uncertainty of the course of any disease not long watched, and the many unexpected turns it may take.
I think I am not the first to utter the following caution : —
Beware how you take away hope from any human being. Nothing is clearer than that the merciful Creator intends to blind most people as they pass down into the dark valley. Without very good reasons, temporal or spiritual, we should not interfere with his kind arrangements. It is the height of cruelty and the extreme of impertinence to tell your patient he must die, except you are sure that he wishes to know it, or that there is some particular cause for his knowing it. I should be especially unwilling to tell a child that it could not recover; if the theologians think it necessary, let them take the responsibility. God leads it by the hand to the edge of the precipice in happy unconsciousness, and I would not open its eyes to what he wisely conceals.

"Kingdom of Fear" (12 September 2001)
2000s
Context: The towers are gone now, reduced to bloody rubble, along with all hopes for Peace in Our Time, in the United States or any other country. Make no mistake about it: We are At War now — with somebody — and we will stay At War with that mysterious Enemy for the rest of our lives.
