What is objectionable, what is dangerous, about extremists is not that they are extreme, but that they are intolerant. The evil is not what they say about their cause, but what they say about their opponents. There are those who look at things the way they are, and ask why... I dream of things that never were, and ask why not? Only those who dare to fail greatly can ever achieve greatly. I dream of things that never were, and ask why not? It is from numberless diverse acts of courage and belief that human history is shaped. Each time a man stands up for an ideal, or acts to improve the lot of others, or strikes out against injustice, he sends forth a tiny ripple of hope, and crossing each other from a million different centers of energy and daring, those ripples build a current that can sweep down the mightiest walls of oppression and resistance. |
