But science works for evil as well as for good; and both Gauss and lesser mathematicians may be justified in rejoicing that there is one science at any rate, and that their own, whose very remoteness from ordinary human activities should keep it gentle and clean.”” [G.H. Hardy](https://sms4smile.com/quotes/author/g-h-hardy-2/) ## About This Quote This interpretation was drafted with AI assistance. It is one reading of the quote, not the author's own explanation.
