Courage is never to let your actions be influenced by your fears.
If power corrupts, the reverse is also true; persecution corrupts the victims though perhaps in subtler and more tragic ways.
Interpretation
What this quote means
Both power and persecution can lead to corruption, particularly affecting those who suffer from persecution in profound ways.
Arthur Koestler's quote suggests that while the abuse of power can corrupt individuals and institutions, the experience of persecution can also lead to a form of corruption in its victims. This corruption may manifest in subtle yet tragic alterations to the victims' sense of self, morality, and worldview, implying that suffering and oppression can have lasting psychological effects that alter a person's character and behavior.

Not only is the past of a person with no memory inaccessible; his ability to think about the future is imperilled. Time travel, then, is ultimately - and paradoxically - an exercise in remembering. And without that capacity it simply cannot exist.
Churchgoers feel righteous, responsible, and obedient to God's will. They view anyone unlike themselves as devoid of values, and therefore unworthy of God's love.

The various modes of worship, which prevailed in the Roman world, were all considered by the people, as equally true; by the philosopher, as equally false; and by the magistrate, as equally useful. And thus toleration produced not only mutual indulgence, but even religious concord.
