The one thing that unifies men in a given age is not their individual philosophies but the dominant problem that these philosophies are designed to solve.
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 BarzunThe truth is, when all is said and done, one does not teach a subject, one teaches a student how to learn it.
