No method nor discipline can supersede the necessity of being forever on the alert. What is a course of history, or philosophy, or poetry, or the most admirable routine of life, compared with the discipline of looking always at what is to be seen? Will you be a reader, a student merely, or a seer?
—Henry David Thoreau, Walden, chapter four, 1854.
To see what is in front of one’s nose needs a constant struggle.
—George Orwell, “In Front of Your Nose,” London’s Tribune, 1946.
