Famous quotes containing the words optical and/or companions:
“The convent, which belongs to the West as it does to the East, to antiquity as it does to the present time, to Buddhism and Muhammadanism as it does to Christianity, is one of the optical devices whereby man gains a glimpse of infinity.”
—Victor Hugo (1802–1885)
“Dear fellow-artist, why so free
With every sort of company,
With every Jack and Jill?
Choose your companions from the best;
Who draws a bucket with the rest
Soon topples down the hill.”
—William Butler Yeats (1865–1939)
