More quotes by Augustus De Morgan
The moving power of mathematical invention is not reasoning but imagination.
Augustus De Morgan
All existing things upon this earth, which have knowledge of their own existence, possess, some in one degree and some in another, the power of thought, accompanied by perception, which is the awakening of thought by the effects of external objects upon the senses.
Augustus De Morgan
Every science that has thriven has thriven upon its own symbols: logic, the only science which is admitted to have made no improvements in century after century, is the only one which has grown no symbols.
Augustus De Morgan
Common integration is only the memory of differentiation... The different artifices by which integration is effected, are changes, not from the known to the unknown, but from forms in which memory does not serve us to those in which it does.
Augustus De Morgan
But the gambling reasoner is incorrigible: if he would but take to squaring the circle, what a load of misery would be saved.
Augustus De Morgan
The sacred writings excepted, no Greek has been so much read and so variously translated as Euclid.
Augustus De Morgan
I did not hear what you said, but I absolutely disagree with you.
Augustus De Morgan
I don't quite hear what you say, but I beg to differ entirely with you.
Augustus De Morgan
Imagine a person with a gift of ridicule [He might say] First that a negative quantity has no logarithm secondly that a negative quantity has no square root thirdly that the first non-existent is to the second as the circumference of a circle is to the diameter.
Augustus De Morgan
My opinion of mankind is founded upon the mournful fact that, so far as I can see, they find within themselves the means of believing in a thousand times as much as there is to believe in.
Augustus De Morgan
As to writing another book on geometry [to replace Euclid] the middle ages would have as soon thought of composing another New Testament.
Augustus De Morgan
Wrong hypotheses, rightly worked from, have produced more useful results than unguided observations.
Augustus De Morgan
Great fleas have little fleas upon their backs to bite 'em, And little fleas have lesser fleas, and so ad infinitum, And the great fleas themselves, in turn, have greater fleas to go on, While these again have greater still, and greater still, and so on.
Augustus De Morgan
