Howard Zinn, Changing minds, one at a time, 2005: "We were not born critical of existing society. There was a moment in our lives (or a month, or a year) when certain facts appeared before us, startled us, and then caused us to question beliefs that were strongly fixed in our consciousness — embedded there by years of family prejudices, orthodox schooling, imbibing of newspapers, radio, and television. This would seem to lead to a simple conclusion: that we all have an enormous responsibility to bring to the attention of others information they do not have, which has the potential of causing them to rethink long-held ideas."
