Life is made up of a series of judgments on insufficient data, and if we waited to run down all our doubts, it would flow past us.

Sufficient to today are the duties of today. Don’t waste life in doubts and fears; spend yourself on the work before you, well assured that the right performance of this hour’s duties will be the best preparation for the hours and ages that will follow it.
Ralph Waldo Emerson (1803-1882) American essayist, lecturer, poet
“Immortality,” Letters and Social Aims (1876)

Brute force plays a much larger part in the government of the world than it did before 1914, and what is especially alarming, force tends increasingly to fall into the hands of those who are enemies of civilization. The danger is profound and terrible; it cannot be waved aside with easy optimism. The fundamental cause of the trouble is that in the modern world the stupid are cocksure while the intelligent are full of doubt.
Bertrand Russell (1872-1970) English mathematician and philosopher
“The Triumph of Stupidity,” New York American (1933-05-10)
(Source)
Often paraphrased, "The trouble with the world is that the stupid are cocksure, and the intelligent are full of doubt." See also Yeats and Bukowski.

Doubt is not a pleasant condition, but certainty is an absurd one.
[Le doute n’est pas une condition agréable, mais la certitude est absurde.]

In all affairs — love, religion, politics or business — it’s a healthy idea, now and then, to hang a question mark on the things you have long taken for granted.
Bertrand Russell (1872-1970) English mathematician and philosopher
(Attributed)
Widely attributed to Russell, but not found in any of his online published works or cited to any source.
There are numerous variations on this quote, e.g.,
In all affairs it's a healthy idea now and then to hang a question mark on the things you have taken for granted.
And mixes and matches between those two.
Earliest references of long-form quotation I could find:I also found in Alexander Chittick, Social Evolution, "The Evolution of Capital and Labor" (1919), regarding the plight of laborers:
- Readers Digest, "Quotable Quotes" filler (1940-08)
- Forbes, "Thoughts on the Business of Life" (1950-02-01)
They should be taught [...] to take nothing for granted in love, religion, politics, or business.
The combination of taking for granted and the same list of four affair topics seems more than coincidence. Was Chittick riffing off of an unfound Russell comment? Did someone attribute a variation of Chittick's passage to Russell? The answer is unclear.
We know accurately only when we know little, with knowledge doubt increases.

In my opinion, any faith that cannot withstand a little shaking isn’t constructed too well to begin with. Jesus built his church on a rock, not on swampland.

Those who believe that they believe in God, but without passion in their hearts, without anguish in mind, without uncertainty, without doubt, without an element of despair even in their consolation, believe only in the God idea, not in God Himself.
[Los que sin pasión de ánimo, sin congoja, sin incertidumbre, sin duda, sin la desesperación en el consuelo, creen creer en Dios, no creen sino en la idea de Dios, más no en Dios mismo.]

Alt. trans. [tr. Kerrigan (1972)]: "Whoever believes he believes in God, but believes without passion, without anguish, without uncertainty, without doubt, without despair-in-consolation, believes only in the God-Idea, not in God Himself."
Original Spanish.
In Unamuno's earlier, unpublished work Treatise on the Love of God [Tratado del amor de Dios], ch. 3 "What is Faith?" (1905-08) [tr. Orringer], he used this same phrase and surrounding text: "Those without passion in their soul, without anguish, without uncertainty, without doubt, without despair in consolation, think they believe in God; they believe only in the idea of God, but not in God Himself."
Shake off all the fears and servile prejudices under which weak minds are servilely crouched. Fix reason firmly in her seat, and call to her tribunal every fact, every opinion. Question with boldness even the existence of a god; because, if there be one, he must more approve the homage of reason, than that of blindfolded fear.
Thomas Jefferson (1743-1826) American political philosopher, polymath, statesman, US President (1801-09)
