The subtle and deadly change of heart that might occur in you would be involved with the realization that a civilization is not destroyed by wicked people; it is not necessary that people be wicked but only that they be spineless.
“There exists, for everyone, a sentence — a series of words — that has the power to destroy you. Another sentence exists, another series of words, that could heal you. If you’re lucky you will get the second, but you can be certain of getting the first.”
Philip K. Dick
