“Visions may be moral, political, economic, religious, or social. In these or other realms, we sacrifice for our visions and sometimes, if need be, face ruin rather than betray them. Where visions conflict irreconcilably, whole societies may be torn apart. Conflicts of interests dominate the short run, but conflicts of visions dominate history. We will do almost anything for our visions, except think about them.” Thomas Sowell, A Conflict of Visions: Ideological Origins of Political Struggles, xii.
