The difficulty of confuting this assertion, arises merely from its generality and comprehension; to overthrow it by a detail of distinct facts, requires a wider survey of the world than human eyes can take; the progress of reformation is gradual and silent, as the extension of evening shadows; we know that they were short at noon, and are long at sunset, but our senses were not able to discern their increase: we know of every civil nation, that it was once savage, and how was it reclaimed but by precept and admonition?
Mankind are universally corrupt, but corrupt in different degrees; as they are universally ignorant, yet with greater or less irradiations of knowledge. How has knowledge or virtue been increased and preserved in one place beyond another, but by diligent inculcation and rational enforcement?
Books of morality are daily written, yet its influence is still little in the world; so the ground is annually ploughed, and yet multitudes are in want of bread. But, surely, neither the labours of the moralist nor of the husbandman are vain: let them for a while neglect their tasks, and their usefulness will be known; the wickedness that is now frequent will become universal, the bread that is now scarce would wholly fail.
The power, indeed, of every individual is small, and the consequence of his endeavours imperceptible, in a general prospect of the world. Providence has given no man ability to do much, that something might be left for every man to do. The business of life is carried on by a general co-operation; in which the part of any single man can be no more distinguished, than the effect of a particular drop when the meadows are floated by a summer shower: yet every drop increases the inundation, and every hand adds to the happiness or misery of mankind.
That a writer, however zealous or eloquent, seldom works a visible effect upon cities or nations, will readily be granted. The book which is read most, is read by few, compared with those that read it not; and of those few, the greater part peruse it with dispositions that very little favour their own improvement.
It is difficult to enumerate the several motives which procure to books the honour of perusal: spite, vanity, and curiosity, hope and fear, love and hatred, every passion which incites to any other action, serves at one time or other to stimulate a reader.
