The poetic impulse is ...

The poetic impulse is distinct from ideas about things or feelings about things, though it may use these. It's more like a desire to separate a piece of one's experience & set it up on its own, an isolated object never to trouble you again, at least not for a bit. In the absence of this impulse nothing stirs.
 Philip Larkin

Quotes from the same author

Many modern novels have a beginning, a muddle and an end.
 Philip Larkin
My mother, who hates thunderstorms, Holds up each summer day and shakes It out suspiciously, lest swarms Of grape-dark clouds are lurking there.
 Philip Larkin
Novels are about other people and poems are about yourself.
 Philip Larkin
Slowly light strengthens, and the room takes shape. It stands plain as a wardrobe, what we know, Have always known, know that we can't escape, Yet can't accept. One side will have to go. Meanwhile telephones crouch, getting ready to ring In locked-up offices, and all the uncaring Intricate rented world begins to rouse. The sky is white as clay, with no sun. Work has to be done. Postmen like doctors go from house to house.
 Philip Larkin
Spring, of all seasons most gratuitous, Is fold of untaught flower, is race of water, Is earth's most multiple, excited daughter; And those she has least use for see her best, Their paths grown craven and circuitous, Their visions mountain-clear, their needs immodest.
 Philip Larkin
