Philip Zimbardo... In contrast to the "banality of evil," which posits that ordinary people can be responsible for the most despicable acts of cruelty and degradation of their fellows, I posit the "banality of heroism," which unfurls the banner of the heroic Everyman and Everywoman who heed the call to service to humanity when their time comes to act. When that bell rings, they will know that it rings for them. It sounds a call to uphold what is best in human nature that rises above the powerful pressures of Situation and System as the profound assertion of human dignity opposing evil.
