As we celebrate American Independence Day, the 4th of July, we are duly reminded of the deep passions that made such a difference in protecting the God-given rights to life, liberty, and the pursuit of happiness. Ignorance and lethargy remain hostile to these precious rights. That is why vigilance is always necessary. We may sing about "the land of the free and the home of the brave" – but in a deeper sense America is the land of the free because of the brave. And that essential bravery takes passion.
