Chew the cud of politics. [ Swift ]

Some wits can digest before others can chew. [ Proverb ]

Read and take your nourishment in at your eyes; shut up your mouth and chew the cud of understanding. [ Congreve ]

Learn a man's limitations. If you make him bite off more than he can chew, don't get mad at him if he has to spit it out. [ George Horace Lorimer ]

Because half a dozen grasshoppers under a fern make the field ring with their importunate chink, whilst thousands of great cattle, reposing beneath the shadow of the British oak, chew the cud and are silent, pray do not imagine that those who make the noise are the only inhabitants of the field. [ Burke ]

They that have read about everything are thought to understand everything too; but it is not always so. Reading furnishes the mind only with the materials of knowledge; it is thinking that makes what we read ours. We are of the ruminating kind, and it is not enough to cram ourselves with a great load of collections, - we must I chew them over again. [ Channing ]
