The opposite of love is not hate, it's indifference. The opposite of art is not ugliness, it's indifference. The opposite of faith is not heresy, it's indifference. And the opposite of life is not death, it's indifference.
—Elie Wiesel
The universe seems neither benign nor hostile, merely indifferent to the concerns of such puny creatures as we are.
—Carl Sagan in Cosmos
Time is not your friend. It doesn't care if you live fast or die slow, if you are or if you aren't. It was here before you arrived and it will go on after you leave. Time doesn't care who wins or who loses, if your life span is full or empty, honorable or shameful. Time is indifferent.
—Laura Wiess in Leftovers
The absolute yearning of one human body for another particular one and its indifference to substitutes is one of life's major mysteries.
—Iris Murdoch
Throughout history it has been the inaction of those who could have acted, the indifference of those who should have known better, the silence of the voice of justice when it mattered most, that have made it possible for evil to triumph.
—Haile Selassie
