While the phrase “survival of the fittest” conjures up images of cutthroat competition and everyone fighting for themselves, the reality is that it’s the most clever and cooperative live on — both in the animal kingdom and the human world. The development of vaccines and people cooperating by wearing masks and staying home are pursuits more likely to conquer Covid-19 than immune systems alone. That’s why jakuniku-kyoushoku, or the law of the jungle, can represent cooperation as well as competition — the former is, after all, a successful survival strategy that has gotten us this far.
Meaning: The weak are meat; the strong do eat, the law of the jungle, it’s a dog-eat-dog world, the weakest goes to the wall, survival of the fittest, the stronger prey upon the weaker.
Literal translation and kanji breakdown: In order, 弱肉強食 reads “weak meat, strong food”, which arranges neatly to mean “the flesh of the weak is the food of the strong”.
Jakuniku-kyoushoku: The Origins
The expression, or at least a rough version of it, is attributed to an 8th century Tang dynasty poet, prose writer and government official, Han Yu. He’s considered one of the eight major writers of the Tang and Song dynasties and was a champion of clear, concise prose. He penned a version of “the flesh of the weak is the food of the strong” in a text known as “Preface to seeing off the Buddhist master Wenchang”, which, given his disgust for Buddhism and its followers, may have been more of a threat than a motivational speech.
