what is the idea of wisdom expressed in ecclesiastes?

Answer 1

The work emphatically proclaims all the actions of man to be inherently "futile" and/or "meaningless," as the lives of both wise and foolish men end in death. While the teacher clearly promotes wisdom for the enjoyment of an earthly life, he is unable to ascribe eternal meaning to it. In light of this perceived senselessness, the teacher suggests that one should enjoy the simple pleasures of daily life, such as eating, drinking, and taking enjoyment in one's work, which are gifts from the hand of God. Ultimately the author concludes that his search for meaning to this life points to the fact that humankind's paramount duty is to "Fear God and keep his commandments (12:13)."
