"Competition is the law of the jungle, but cooperation is the law of civilization"
- Peter Kropotkin (1842-1921)

UPDATE:
Thanks to some responders, found out that this “quote” is not an actual quote of Kroptkin. He actually thought the “jungle” showed cooperation as well.
A thread on how this misquote has been spread:

@rberger hi, do you have any source for this quote ? It feels a little off Kropotkine view of the world

@blickbluck Yep, you are correct now that I look into it. I should have known better to just repost a meme like that without checking.
Looks like its a common misquoting of Kropotkin.

Found this thread on the subject:

“To quote Shaun Pitt, "You probably already know this but the quote doesn't fit Kropotkin's view of 'the jungle' as he saw mutual aid [in animals and even] in the most 'simple' organisms…”
