An enemy always represents a weakness. This might be fear of physical pain, but it could also be a premature sense of victory or the desire to abandon the fight because it is no longer worthwhile.
We must dress according to the dictates of fashion, make love whether we feel like it or not, kill in the name of our country, wish time away so that retirement comes more quickly, elect politicians, complain about the cost of living, change our hairstyle, criticize anyone who's different, go to a religious service and beg forgiveness for our sins and puff ourselves up with pride because we know the truth and despise the other tribe who worships a false god.
Only children believe they're capable of everything. They're trusting and fearless; they believe in their own power and get exactly what they want. When children grow up, they start to realize that they're not as powerful as they thought and that they need other people in order survive. Then the child begins to love and to hope his love will be requited; and as life goes on, he develops an ever-greater need to be loved in return, even if that means having to give up his power. We all end up where we are now: Grown-ups doing everything we can to be accepted and loved.
