Famous quotes containing the words tests, latent and/or tuberculosis:
“It is not the literal past that rules us, save, possibly, in a biological sense. It is images of the past.... Each new historical era mirrors itself in the picture and active mythology of its past or of a past borrowed from other cultures. It tests its sense of identity, of regress or new achievement against that past.”
—George Steiner (b. 1929)
“The latent causes of faction are thus sown in the nature of man.”
—James Madison (1751–1836)
“With sighs more lunar than bronchial,
Howbeit eluding fallopian diagnosis,
She simpers into the tribal library and reads
That Keats died of tuberculosis . . .”
—Allen Tate (1899–1979)
