A Quote by Ambrose Bierce

Doubt is the father of invention. — © Ambrose Bierce
Doubt is the father of invention.
Galileo called doubt the father of invention; it is certainly the pioneer.
Not far from the invention of fire we must rank the invention of doubt.
Can that which is the greatest virtue in philosophy, doubt (called by Galileo the father of invention), be in religion what the priests term it, the greatest of sins?
You cannot show real respect to your parents by perpetuating their errors.... Do you consider that the inventor of a steel plow cast a slur upon his father who scratched the ground with a wooden one? I do not consider that an invention by the son is a slander upon the father; I regard each invention simply as an improvement; and every father should be exceedingly proud of an ingenious son. If Mr. Talmage has a son, it will be impossible for him to honor his father except by differing with him.
Necessity is not merely the father of invention; it is the father of courage.
There can be no doubt but that he who has the most materials has the greatest means of invention.
There is too much fathering going on just now and there is no doubt about it fathers are depressing. Everybody now-a-days is a father, there is father Mussolini and father Hitler and father Roosevelt and father Stalin and father Trotsky and father Blum and father Franco is just commencing now and there are ever so many more ready to be one. Fathers are depressing. England is the only country now that has not got one and so they are more cheerful there than anywhere. It is a long time now that they have not had any fathering and so their cheerfulness is increasing.
The greatest invention of the nineteenth century was the invention of the method of invention.
I have no doubt that my origin and ethnicity have strongly influenced controversy over my invention of email.
There are many different kinds of doubt. When we doubt the future, we call it worry. When doubt other people we call is suspicion. When we doubt ourselves we call it inferiority. When we doubt God we call it unbelief. When we doubt what we hear on television we call it intelligence! When we doubt everything we call it cynicism or skepticism.
If necessity is the mother of invention, conflict is its father.
Necessity may be mother of invention, but fun is the father.
If necessity is the mother of invention, discontent is the father of progress.
Like belief, doubt takes a lot of different forms, from ancient Skepticism to modern scientific empiricism, from doubt in many gods to doubt in one God, to doubt that recreates and enlivens faith and doubt that is really disbelief.
In other words, what is supposedly found is an invention whose inventor is unaware of his act of invention, who considers it as something that exists independently of him; the invention then becomes the basis of his world view and actions.
Necessity may be the mother of invention, but play is certainly the father.
