Long before writing and books were in common use, proverbs were the principal means of imparting instruction. In modern times there is not so much need to apply these old sayings as a means of educating the people, but they are rightly considered as "The texts of common life". Earl Russell very aptly described a proverb as "The wisdom of many and the wit of one." We value proverbs chiefly as moral maxims teaching some practical lesson set forth in concise, pithy sentences, which are fixed in the memory without effort, and retained without being burdensome.
From the Preface to "Dictionary of English Proverbs and Proverbial Phrases" [1880]
Proverbs in English for the most part form the basis of this collection. They are arranged according to their import and affinity, and under each of them are grouped translations of their principal equivalents in other languages. By this means are formed natural families of proverbs, the several members of which acquire increased significance from the light they reflect on each other. At the same time, a source of lively interest is opened for the reader, who is thus enabled to observe the manifold diversities of form which the same thought assumes, as expressed in different times and by many languages; to trace the unity in variety which pervades the oldest and most universal monuments of opinion and sentiment among mankind; and to verify for himself the truth of Lord Bacon's well-known remark, that "the genius, wit, and spirit of a nation are discovered in its proverbs".
Touching as they do upon so wide a range of human concerns, proverbs are necessarily associated with written literature. Sometimes they are created by it; much oftener they are woven into its texture. Personal anecdotes turn upon them in many instances; and not unfrequently they have figured in national history, or have helped to preserve the memory of events, manners, usages, and ideas, some of which have left little other record of their existence.
