Jean Louis Armand de Quatrefages de Bréau, Popular Science Monthly (1873)
“ I mean the silk-worm. Its history is full of serious instruction. It teaches us not to despise a being because, at first, it seems useless; it proves that creatures, in appearance the most humble, may play a part of great importance to the world; it shows us that the most useful things are often slow to attract public attention, but that sooner or later their day of justice arrives. It teaches us, consequently, not to despair when valuable ideas or practical inventions are not at first welcomed as they should be, for, though their triumph is delayed, it is not less sure. ”
