Bolesław Prus,
On Discoveries and Inventions
“ Likewise, we shall say that a naturalist has made a discovery if he has found a hitherto unknown plant, animal, or stone. But if someone builds a harvester, a clock, a sewing machine – if he obtains paints from coal, if he makes a steel different from that which exists today – then this person makes an invention, that is, makes a thing previously unknown, which nature itself could not make and maintain. History, the study of what has happened among people in the past, teaches us that discoveries and inventions have not sprung into existence full-blown, but have appeared gradually. ”
