" Thought—he told himself quietly—is a weapon one uses in order to act. No action was possible. Thought is the tool by which one makes a choice. No choice was left to him. Thought sets one’s purpose and the way to reach it. In the matter of his life being torn piece by piece out of him, he was to have no voice, no purpose, no way, no defense. "

― Ayn Rand , Atlas Shrugged
