Although Solomon’s search was undertaken very seriously, he did not exclude areas which are normally associated with a light and frivolous lifestyle. As a deliberate policy, he chose to explore mirth: the pursuit of pleasure for its own sake.
Disregarding the eternal nature of the soul and its great worth, the pleasure seeker treats himself as if he could be entirely satisfied with trifles of this world. But they leave so many questions unanswered and even as man enjoys these insubstantial things, they impress upon him that his needs are far greater and that there is a large part of him that remains unsatisfied. In trying to find happiness in these things, he reduces himself to the level of an animal without an eternal soul and this is most painful for him. Is he really prepared to sacrifice his higher being in the interests of gaining some short-lived enjoyment, and what will happen to him when this brief life is over and the flow of pleasure ceases? The thought weighs heavily upon him and he finds that what at first sight seems designed to give pleasure only increases a sense of futility at the transient nature of his life. This also is vanity.
