“Once you believe that there is a final answer to human ills. If there is just a final answer then no sacrifice is too great for it. Even if you have to kill people for it. This is the one end, permanent, bliss, happiness, for mankind. Surely, worth it.

If you believe there is a single answer to the single question- The true answer, all other answers then being false- all these answers can be put together and harmonize with each other to create the perfect universe, then there is temptation if you think you have it, to do awful things.”

Isaiah Berlin
