"Knowledge & half-knowledge" 



Four frogs sat upon a log that lay floating on the edge of a river. Suddenly the log was caught
by the current and 
swept slowly down the stream. The frogs were delighted and absorbed, for never before had
they sailed. 
At length the first frog spoke, and said, "This is indeed a most marvellous log. It moves as if
alive. No such log was ever known before." 

Then the second frog spoke, and said, "Nay, my friend, the log is like other logs, and does not
move. It is the river 
that is walking to the sea, and carries us and the log with it." 

And the third frog spoke, and said, "It 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 a strange thing happened. The three frogs got together and pushed the fourth frog off the
log into the river.
