Don't imagine that you'll discover {the truth} by accumulating more knowledge. Knowledge creates doubt, and doubt makes you ravenous for more knowledge. You can't get full eating this way.
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.
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.
Satisfy yourself beyond all doubt that you are qualified for the course to which you now aspire.....and try to achieve something in your own land before you venture on a strange one.
The majority of mankind is lazyminded, incurious, absorbed in vanities, and tepid in emotion, and is therefore incapable of either much doubt or much faith.
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.
If I had any doubts at all about the justice of my dislike for Shakespeare, that doubt vanished completely. What a crude, immoral,vulgar, and senseless work Hamlet is. The whole thing is based on pagan vengeance; the only aim is to gather together as many effects as possible; there is no rhyme or reason about it.
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.
I went over the heads of the things a man reckons desirable. No doubt invisibility made it possible to get them, but it made it impossible to enjoy them when they are got.
Suspicions that the mind, of itself, gathers, are but buzzes; but suspicions that are artificially nourished and put into men's heads by the tales and whisperings of others, have stings.
