Solomon and Worldly Pleasure

Solomon had thoroughly experienced all avenues of pleasure, all avenues of sensuality, all avenues of wealth, honor, folly, and the pursuit of knowledge. He also sinned in giving way to every excess of life which his position made possible and comes to the realization of the uselessness of it all. He concludes that the result of his efforts have been made him empty and that there is nothing new under the sun, but all is part of the endless, frustrating circularity. His attitude was spoken in the recurring phrase, "vanity of vanities, all is vanity, saith the preacher." In Ecclesiastes, the world is convicted of its vanity by one who has drunk of every spring.
