It's murder to doubt yourself in life. It took until I was 45 to get to that point. As hard as it is in your work, it's harder in your life. But it can be done.
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.
I am, and have been for years, a confirmed anti-vaccinationist...I have not the least doubt in my mind that vaccination is a filthy process that is harmful in the end.
When in doubt, tell the truth. That maxim I did invent, but never expected it to be applied to me. I did say, "When you are in doubt," but when I am in doubt myself I use more sagacity.
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.
What doubt can you have of the Creator when you behold His creation?... Who has decked the heavenly firmament with its stars? Who has clothed the earth in its beauty? How could it be without the creator?
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 believe that the starting point of faith is some doubt, not bein' so full of yourself and so confident that you are right and that God speaks only to us and doesn't speak to others, that God only cares about us and doesn't care about others.
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.
