We have, even using 10 times the energy, same results. Remember, Republicans want to starve children and Christians want to keep them ignorant by challenging Darwininianism.
Ideas and purported truths are at the foundation of all and these precede and rule all action. There is no one alive who doesn't think they are following and living some version of the truth. False ideas are ruinous, evidence communism under which some 100 million people were killed directly or indirectly at the hands of communist rulers in the 20th Century. If people believe they are lumps of consciousless material and that death is the end, they will behave one way (like Bill Clinton, for example). If they've done the hard work to know better (and I know this is a values-charged statement), behavior changes radically. And it's as hard to know truth as it is to live it, especially in America today with all its distractions. But we all seek truth, however misdirected our efforts. The "saving grace" in all this is that truth is real and has a resonance all its own, so, ultimately, it will prevail. And this little sermon is, needless-to-say, IMHO . . .
