Famous quotes containing the word object:
“Does our ferocity not derive from the fact that our instincts are all too interested in other people? If we attended more to ourselves and became the center, the object of our murderous inclinations, the sum of our intolerances would diminish.”
—E.M. Cioran (b. 1911)
