Self-preservation, nature's first great law, all the creatures, except man, doth awe.
Andrew MarvellMeanwhile the mind, from pleasure less, Withdraws into its happiness; The mind, that ocean where each kind Does straight its own resemblance find; Yet it creates, transcending these, Far other worlds, and other seas; Annihilating all that's made To a green thought in a green glade ... Such was that happy garden-state.
