“Thus Winter falls,
A heavy gloom oppressive o’er the world
Through Nature shedding influence malign,
And rouses up the seeds of dark disease.
The soul of man dies in him, loathing life,
And black with more than melancholy views.”
—James Thomson (1700–1748)
“Perspective, as its inventor remarked, is a beautiful thing. What horrors of damp huts, where human beings languish, may not become picturesque through aerial distance! What hymning of cancerous vices may we not languish over as sublimest art in the safe remoteness of a strange language and artificial phrase! Yet we keep a repugnance to rheumatism and other painful effects when presented in our personal experience.”
—George Eliot [Mary Ann (or Marian)
