In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion.
It should be borne in mind that there is nothing more difficult to arrange, more doubtful of success, and more dangerous to carry through than initiating changes. The innovator makes enemies of all those who prospered under the old order, and only lukewarm support is forthcoming from those who would prosper under the new. Their support is lukewarm ... partly because men are generally incredulous, never really trusting new things unless they have tested them by experience.
The nearer a conception comes towards finality, the nearer does the dynamic relation, out of which this concept has arisen, draw to a close. To know is to lose.
Here's the truth: even if countries like the United States curb our emissions, if growing countries like India - with soaring energy needs - don't also embrace cleaner fuels, then we don't stand a chance against climate change.
Repeal the Missouri Compromise - repeal all compromises - repeal the Declaration of Independence - repeal all past history, you still can not repeal human nature. It still will be the abundance of man's heart, that slavery extension is wrong; and out of the abundance of his heart, his mouth will continue to speak.
[My advice] will one day be found
With other relics of 'a former world,'
When this world shall be former, underground,
Thrown topsy-turvy, twisted, crisped, and curled,
Baked, fried or burnt, turned inside-out, or drowned,
Like all the worlds before, which have been hurled
First out of, and then back again to Chaos,
The Superstratum which will overlay us.
What, then, is the true Gospel of consistency? Change. Who is the really consistent man? The man who changes. Since change is the law of his being, he cannot be consistent if he stick in a rut.
