We must assume our existence as broadly as we in any way can; everything, even the unheard - of, must be possible in it. This is at bottom the only courage that is demanded of us: to have courage for the most strange, the most inexplicable.
When we're in a human body, we don't care about universal collapse - instead, we care only about a meeting of the eyes, a glimpse of bare flesh, the caressing tones of a loved voice, joy, love, light, the orientation of a house plant, the shade of a paint stroke, the arrangement of hair.
