“Now I have entered the year without words.
I note the queer entrance and the exact voltage.”
—Anne Sexton (19281974)
“Private property is held sacred in all good governments, and particularly in our own. Yet shall the fear of invading it prevent a general from marching his army over a cornfield or burning a house which protects the enemy? A thousand other instances might be cited to show that laws must sometimes be silent when necessity speaks.”
