I know so many good people who are anxious to increase happiness, but only on their own conditions; they feel that they estimate exactly what the quantity and quality of joy ought to be, and they treat the joy which they do not themselves feel as an offence against truth. It is from these beliefs, I have often thought, that much of the unhappiness of family circles arises, the elders not realising how the world moves on, how new ideas come to the front, how the old hopes fade or are transmuted. They see their children liking different thoughts, different occupations, new books, new pleasures; and instead of trying to enter into these things, to believe in their innocence and their naturalness, they try to crush and thwart them, with the result that the boys and girls just hide their feelings and desires, and if they are not shamed out of them, which sometimes happens, they hold them secretly and half sullenly, and plan how to escape as soon as they can from the tender and anxious constraint into a real world of their own. And the saddest part of all is that the younger generation learn no experience thus; but when they form a circle of their own and the same expansion happens, they do as their parents did, saying to themselves, "My parents lost my confidence by insisting on what was not really important; but _my_ objections are reasonable and justifiable, and my children must trust me to know what is right." We must realise then that elasticity and sympathy are the first of duties, and that if we embark upon the crusade of joy, we must do it expecting to find many kinds of joy at work in the world, and some which we cannot understand. We may of course mistrust destructive joy, the joy of selfish pleasure, rough combativeness, foolish wastefulness, ugly riot--all the joys that are evidently dogged by sorrow and pain; but if we see any joy that leads to self-restraint and energy and usefulness and activity, we must recognise it as divine. We may have then our private fancies, our happy pursuits, our sweet delights; we may practise them, sure that the best proof of their energy is that they obviously and plainly increase and multiply our own happiness. But if we direct others at all, it must be as a signpost, pointing to a parting of roads and making the choice clear, and not as a policeman enforcing the majesty of our self-invented laws. Everything that helps us, invigorates us, comforts us, sustains us, gives us life, is right for us; of that we need never be in any doubt, provided always that our delight is not won at the expense of others; and we must allow and encourage exactly the same liberty in others to choose their own rest, their own pleasure, their own refreshment. What would one think of a host, whose one object was to make his guests eat and drink and do exactly what he himself enjoyed? And yet that is precisely what many of the most conscientious people are doing all day long, in other regions of the soul and mind.
