In any assembly the simplest way to stop transacting business and split the ranks is to appeal to a principle.
Jacques BarzunOne great aim of revision is to cut out. In the exuberance of composition it is natural to throw in - as one does in speaking - a number of small words that add nothing to meaning but keep up the flow and rhythm of thought. In writing, not only does this surplusage not add to meaning, it subtracts from it. Read and revise, reread and revise, keeping reading and revising until your text seems adequate to your thought.
Jacques BarzunIn ordinary speech the words perception and sensation tend to be used interchangeably, but the psychologist distinguishes. Sensations are the items of consciousness--a color, a weight, a texture--that we tend to think of as simple and single. Perceptions are complex affairs that embrace sensation together with other, associated or revived contents of the mind, including emotions.
