“I speak without exaggeration when I say that I have constructed 3,000 different theories in connection with the electric light, each one of them reasonable and apparently likely to be true. Yet only in two cases did my experiments prove the truth of my theory. My chief difficulty was in constructing the carbon filament... Every quarter of the globe was ransacked by my agents, and all sorts of the queerest materials used, until finally the shred of bamboo, now utilized by us, was settled upon.”

“Economists can never be free of from difficulties unless they will distinguish between a theory and the application of a theory.”

“Psychology should be the chief basic science upon which the practices of education depend. It should have supplied education with the information it needs concerning the processes of understanding, learning, and thinking, among other things. One of the difficulties has been that such theory as has been developed has been based primarily upon studies of behavior of rats and pigeons. As someone has said, some of the theory thus developed has been an insult even to the rat.”

“Yet the widespread planetary theories, advanced by Ptolemy and most other astronomers, although consistent with the numerical data, seemed likewise to present no small difficulty. For these theories were not adequate unless they also conceived certain equalizing circles, which made the planet appear to move at all times with uniform velocity neither on its deferent sphere nor about its own epicycle's center.”

“It is easier taking the beaten path than making our way over bogs and precipices. The great difficulty in philosophy is to come to every question with a mind fresh and unshackled by former theories, though strengthened by exercise and information.”

“I have a name for people who went to the extreme efficient market theory-which is "bonkers". It was an intellectually consistent theory that enabled them to do pretty mathematics. So I understand its seductiveness to people with large mathematical gifts. It just had a difficulty in that the fundamental assumption did not tie properly to reality.”

“Evolution ... is really two theories, the vague theory and the precise theory. The vague theory has been abundantly proved.... The precise theory has never been proved at all. However, like relativity, it is accepted on faith.... On getting down to actual details, difficulties begin.”

“We were an ill-matched pair, my husband and I, from the very outset; he, with very high ideas of a husband's authority and a wife's submission, holding strongly to the 'master-in-my-own-house theory,' thinking much of the details of home arrangements, precise, methodical, easily angered and with difficulty appeased.”
