"Fools rush in where angels fear to tread"
is true enough, and well enough expressed to bear frequent quotation, but it is not a "fragment of elder wisdom." It is merely Pope's excellent way of saying that foolish people will interfere in delicate matters in which wise people would never think of meddling. Here, again, the language is not particularly simple as in proverbs, and this will help us to remember that quotations are not proverbs. There is, however, a quotation from a poem by Patrick A. Chalmers, a present-day poet, which has become as common as a proverb:—
"What's lost upon the roundabouts
We pulls up on the swings."
The fact that this is expressed simply and even ungrammatically does not, of course, turn it into a proverb.
Though many of the proverbs which are repeated in nearly all the languages of the world are without date, we know the times when a few of them were first quoted. In Greek writings we already find the half-true proverb, "Rolling stones gather no moss;" and, "There's many a slip 'twixt the cup and the lip," which warned the Greeks, as it still warns us, of the uncertainty of human things. We can never be sure of anything until it has actually happened. In Latin writings we find almost the same idea expressed in the familiar proverb, "A bird in hand is worth two in the bush"—a fact which no one will deny.
St. Jerome, who translated the Bible from Greek into Latin in the fourth century and wrote many wise books besides, quotes two proverbs which we know well: "It is not wise to look a gift horse in the mouth," and, "Liars must have good memories." The first again deals, like so many of the early proverbs, with the knowledge of animals. A person who knows about horses can tell from the state of their mouths much about their age, health, and general value. But, the proverb warns us, it is neither gracious nor wise to examine too closely what is given to us freely. It may not be quite to our liking, but after all it is a present.
The proverb, "Liars must have good memories," means, of course, that people who tell lies are liable to forget just what tale they have told on any particular occasion, and may easily contradict themselves, and so show that they have been untruthful. It is necessary, then, for such a person, unless he wishes to be found out, to remember exactly what lies he has told.
Many proverbs have remained in the English language, not so much for the wisdom they contain as for the way in which they express it. Some are in the form of a rhyme—as, "Birds of a feather flock together," and "East and west, home is best." These are always favourites.
Others catch the ear because of their alliteration; that is to say, two or three of their words begin with the same letter. Examples of this are: "Look before you leap." The proverb "A stitch in time saves nine" has something of both these attractions, though it is not exactly a rhyme. Other examples of alliteration in proverbs are: "Delays are dangerous," "Speech is silvern, silence is golden."
A few proverbs are witty as well as wise, and these are, perhaps, the best of all, since they do not, as a rule, exasperate the people to whom they are quoted, as many proverbs are apt to do. Usually these witty proverbs are metaphors.
