"Hayek spoke of the 'fatal conceit' that leads people to believe that 'man is able to shape the world around him according to his wishes'. This brings disaster in its wake, because of the law of unintended consequences. Things never turn out as we expect them to. By the time we realize it, it is often too late to repair the damage. Religious restraints, he believed, represent the rules that work over time. The proof lies in the fact that they, and the civilizations to which they gave rise, have survived. The 'extended order' (his term for modern society) is preserved not by conscious planning but by respecting institutions and traditions, 'many of which men tend to dislike, whose significance they usually fail to understand, whose validity they cannot prove'."
- Jonathan Sacks
