“America, we cannot turn back. Not with so much work to be done. Not with so many children to educate, and so many veterans to care for. Not with an economy to fix and cities to rebuild and farms to save. Not with so many families to protect and so many lives to mend. America, we cannot turn back. We cannot walk alone. At this moment, in this election, we must pledge once more to march into the future. Let us keep that promise - that American promise - and in the words of Scripture hold firmly, without wavering, to the hope that we confess.”

“There is no agreement on the extent to which metabolism could develop independently of a genetic material. In my opinion, there is no basis in known chemistry for the belief that long sequences of reactions can organize spontaneously -- and every reason to believe that they cannot. The problem of achieving sufficient specificity, whether in aqueous solution or on the surface of a mineral, is so severe that the chance of closing a cycle of reactions as complex as the reverse citric acid cycle, for example, is negligible.”
