Incredibly eloquent writing by C.S. Lewis on money and power.
The motives of anyone who desires power over others needs to be questioned. Corruption is not "out there", the seed and the weakness is in all of us, in all moments, but it is possible to guard against its expression. My favorite example of defending against this is the fictional character Maximus in the movie Gladiator. When asked to become emperor of Rome, he is troubled because he dreams of returning home to his wife and child.
