For, were it not good that evil things should also exist, the omnipotent God would almost certainly not allow evil to be, since beyond doubt it is just as easy for Him not to allow what He does not will, as for Him to do what He will.
Truth is more of a stranger than fiction. When in doubt, tell the truth. If you tell the truth, you don't have to remember anything. Most writers regard the truth as their most valuable possession, and therefore are economical in its use.
In relating the circumstances which have led to my confinement within this refuge for the demented, I am aware that my present position will create a natural doubt of the authenticity of my narrative.
A man was meant to be doubtful about himself, but undoubting about the truth; this has been reversed. Nowadays the part of a man that a man does assert is exactly the part he ought not to assert - himself. The part he doubts is exactly the part he ought not to doubt - the Divine Reason.
Should doubt knock at your doorway, just say to those skeptical, disturbing, rebellious thoughts: "I propose to stay with my faith, with the faith of my people."
We cannot know what faith is if we have never had it, and we cannot obtain it as long as we deny it. Faith and doubt cannot exist in the same mind at the same time, for one will dispel the other.
I know that there are those who disagree with the overwhelming scientific evidence on climate change. But here's the thing -- even if you doubt the evidence, providing incentives for energy-efficien cy and clean energy are the right thing to do for our future -- because the nation that leads the clean energy economy will be the nation that leads the global economy. And America must be that nation.
