In Science then the greatest discoverer only differs in degree from his laborious imitator and pupil; but he differs specifically from him whom Nature has gifted for beautiful Art. And in this there is no depreciation of those great men to whom the human race owes so much gratitude, as compared with nature’s favourites in respect of the talent for beautiful art. For in the fact that the former talent is directed to the ever-advancing greater perfection of knowledge and every advantage depending on it, and at the same time to the imparting this same knowledge to others — in this it has a great superiority over [the talent of] those who deserve the honour of being called geniuses. For art stands still at a certain point; a boundary is set to it beyond which it cannot go, which presumably has been reached long ago and cannot be extended further.
