Not the poem which we have read , but that to which we return , with the greatest pleasure, possesses the genuine power, and claims the name of essential poetry .
Those who consider the inessential to be essential
And see the essential as inessential
Don't reach the essential,
Living in the field of wrong intention
Wit and puns aren't just décor in the mind; they're essential signs that the mind knows it's on, recognizes its own software, can spot the bugs in its own program.
