David Herbert Lawrence (11 September 1885 – 2 March 1930) was an English writer and poet. His collected works represent, among other things, an extended reflection upon the dehumanising effects of modernity and industrialisation. Some of the issues Lawrence explores are sexuality, emotional health, vitality, spontaneity, and instinct.

Sometimes snakes can't slough. They can't burst their old skin. Then they go sick and die inside the old skin, and nobody ever sees the new pattern. It needs a real desperate recklessness to burst your old skin at last. You simply don't care what happens to you, if you rip yourself in two, so long as you do get out.
