The old adage, “ all work and no play makes Jack a dull boy,” emphasizes the generally accepted view that there is a great gulf fixed between work and play. Amongst certain groups of individuals idleness is still looked upon as bliss, work is still regarded as a necessary curse. Yet when we consider the fundamentals we find that there is no such hard-and-fast distinction. Rather it is certain forms of work, undertaken mechanically with no clear idea of the end in view—in other words, drudgery— which should be regarded as an antithesis to play. Work which involves self-expression, whether it be the picture of the artist, the finished garment of the needlewoman, the well-cooked dinner of the chef, the expert lesson of the teacher, carries with it that feeling of intense enjoyment of power and of achievement which we associate with play.
