“You can help me to keep my head cool," was the answer. "You stand for the world of common sense which will always win in the long run. When I'm inclined to run amok you'll remind me of England. You'll lower the temperature.”

Stanza 4.
The Second Jungle Book (1895), If— (1896)
Context: If you can talk with crowds and keep your virtue,
Or walk with Kings—nor lose the common touch,
If neither foes nor loving friends can hurt you,
If all men count with you, but none too much;
If you can fill the unforgiving minute
With sixty seconds' worth of distance run,
Yours is the Earth and everything that's in it,
And—which is more—you'll be a Man, my son!
