I cannot believe – and I say this with all the emphasis of which I am capable – that there can ever be any good excuse for refusing to face the evidence in favour of something unwelcome. It is not by delusion, however exalted, that mankind can prosper, but only by unswerving courage in the pursuit of truth.
Many people would claim that the boundary conditions are not part of physics but belong to metaphysics or religion. They would claim that nature had complete freedom to start the universe off any way it wanted. That may be so, but it could also have made it evolve in a completely arbitrary and random manner. Yet all the evidence is that it evolves in a regular way according to certain laws. It would therefore seem reasonable to suppose that there are also laws governing the boundary conditions.
It was true that there was no such person as Comrade Oglivy, but a few lines of print and a couple of faked photographs would soon bring him into existence... Comrade Oglivy, who had never existed in the present, now existed in the past, and when once the act of forgery was forgotten, he would exist just as authentically, and upon the same evidence, as Charlemagne or Julius Caesar.
If an opinion contrary to your own makes you angry, that is a sign that you are subconsciously aware of having no good reason for thinking as you do.... Whenever you find yourself getting angry about a difference of opinion, be on your guard; you will probably find, on examination, that your belief is going beyond what the evidence warrants.
I do not mean to say we are bound to follow implicitly in whatever our fathers did. To do so, would be to discard all the lights of current experience — to reject all progress — all improvement. What I do say is, that if we would supplant the opinions and policy of our fathers in any case, we should do so upon evidence so conclusive, and argument so clear, that even their great authority, fairly considered and weighed, cannot stand; and most surely not in a case whereof we ourselves declare they understood the question better than we.
The truth is that, promoting science isn't just about providing resources, it's about protecting free and open inquiry. It's about ensuring that facts and evidence are never twisted or obscured by politics or ideology. It's about listening to what our scientists have to say, even when it's inconvenient, especially when it's inconvenient. Because the highest purpose of science is the search for knowledge, truth and a greater understanding of the world around us. That will be my goal as President of the United States, and I could not have a better team to guide me in this work.
The fundamentalists deny that evolution has taken place; they deny that the earth and the universe as a whole are more than a few thousand years old, and so on. There is ample scientific evidence that the fundamentalists are wrong in these matters, and that their notions of cosmogony have about as much basis in fact as the Tooth Fairy has.
One of our fan-coloring biographers, who paints small men as very great, inquired of me lately with real affection too, whether he might consider as authentic, the change of my religion much spoken of in some circles. Now this supposed that they knew what had been my religion before, taking for it the word of their priests, whom I certainly never made the confidants of my creed. My answer was "say nothing of my religion. It is known to my God and myself alone. Its evidence before the world is to be sought in my life; if that has been honest and dutiful to society, the religion which has regulated it cannot be a bad one."
There is good evidence that the art of shooting with bows and arrows has not been handed down from any common progenitor of mankind, yet the stone arrow-heads, brought from the most distant parts of the world and manufactured at the most remote periods, are, as Nilsson has shewn, almost identical; and this fact can only be accounted for by the various races having similar inventive or mental powers.
But how can we in good conscience justify war before we've tested a diplomatic agreement that achieves our objectives; that has been agreed to by Iran; that is supported by the rest of the world; and that preserves our options if the deal falls short? How could we justify that to our troops? How could we justify that to the world or to future generations? In the end, that should be a lesson that we've learned from over a decade of war. On the front end, ask tough questions. Subject our own assumptions to evidence and analysis. Resist the conventional wisdom and the drumbeat of war. Worry less about being labeled weak; worry more about getting it right.
When organizations are unable to make new strategies — when people evade the work of choosing among different paths in the future — then you get vague mom-and-apple-pie goals everyone can agree on. Such goals are direct evidence of leadership's insufficient will or political power to make or enforce hard choices.
I don't know what it is about fecundity that so appalls. I suppose it is the teeming evidence that birth and growth, which we value, are ubiquitous and blind, that life itself is so astonishingly cheap, that nature is as careless as it is bountiful, and that with extravagance goes a crushing waste that will one day include our own cheap lives.
It has come to be a legend, and I believe with more foundation of fact than most legends, that Howard University was the outgrowth of the inspiration of a prayer meeting. I hope it is true, and I shall choose to believe it, for it makes of this scene and this occasion a new testimony that prayers are answered. Here has been established a great university, a sort of educational laboratory for the production of intellectual and spiritual leadership among a people whose history, if you will examine it as it deserves, is one of the striking evidences of a soundness of our civilization.
