is neither the log nor the river that moves. The moving is in our thinking. For without thought nothing moves."
And the three frogs began to wrangle about what was really moving. The quarrel grew hotter and louder, but they could not agree.
Then they turned to the fourth frog, who up to this time had been listening attentively but holding his peace, and they asked his opinion.
And the fourth frog said, "Each of you is right, and none of you is wrong. The moving is in the log and the water and our thinking also."
And the three frogs became very angry, for none of them was willing to admit that his was not the whole truth, and that the other two were not wholly wrong.
Then the strange thing happened. The three frogs got together and pushed the fourth frog off the log into the river.
