There are many highly respectable motives which may lead men to prosecute research, but three which are much more important than the rest: intellectual curiosity, professional pride, and finally, ambition, desire for reputation, and the position, even the power or the money, which it brings ... if (anyone) were to tell me that the driving force in his work had been the desire to benefit humanity, then I should not believe him (nor should I think the better of him if I did). - G. H. Hardy (A Mathematician's Apology)
