Know How To Forget

Know how to forget!

But could It teach it?

Easiest of Art, they say

When one learn how

Dull hearts have died

In the acquisition

Is common, though, now

I went to school

But was not wiser

Globe did not teach it 

Nor Logarithm show

"How to forget"!

Say some Philosopher!

Ah, to be erudite 

Enough to know!

Is it in Book?

So, I could buy it

Is it like Planet?

Telescopes would know

If it be invention

It must have Patent.

Rabbi of the wise Book

Don't you know?

[Emily Dickinson]
