"In ancient Greece,
Socrates was reputed to hold knowledge in high esteem. One day an
acquaintance met the great philosopher and said, 'Socrates, do you know
what I just heard about your friend?'

'Hold on a minute,'
Socrates replied. 'Before telling me anything I'd like you to pass a
little test. It's called the Triple Filter Test.'

'Triple filter?'

'That's
right,' Socrates continued. 'Before you talk to me about my friend, it
might be a good idea to take a moment and filter what you're going to
say. The first filter is Truth. Have you made absolutely sure that what
you are about to tell me is true?'

'No,' the man said, 'actually I just heard about it and...'

'All right,' said Socrates. 'So you don't really know if it's true or not.

Now let's try the second filter, the filter of Goodness. Is what you are about to tell me about my friend something good?'

'No, on the contrary...'

So,'
Socrates continued, 'you want to tell me something bad about him, but
you're not certain it's true. You may still pass the test though,
because there's one filter left: the filter of Usefulness. Is what you
want to tell about my friend going to be useful to me?'

'No, not really.'

'Well,' concluded Socrates, 'if what you want to tell me is neither true nor good nor even useful, why tell it to me at all?'

This is why Socrates was a great philosopher and held in such high esteem.

Greeks could not undersand his spiritualdimension. and he was poisioned to death.

Krito asked Socrates before dying ‘” how can we bury you?’.  Socrates replied ,” Krito, you must first catch me the real ‘Me” before asking this question”.  "
