The title "Ecclesiastes" is a transliteration of the Greek translation of the Hebrew term Kohelet (or Qohelet), which means "he who gathers", but which is traditionally translated as "teacher" or "preacher" in English translations of the Bible, the pseudonym used by the author of the book and is from the tradition of mythical Middle Eastern autobiographies, in which a character, describing himself as a king, relates his experiences and draws lessons from them, usually self-critical.
He proclaims that all of a man's actions are inherently "hevel", a term meaning "vain" or "futile", as both wise and foolish end in death. Ecclesiastes clearly endorses wisdom as a means to a well-lived earthly life, for despite this lack of importance of acts, human beings must enjoy the simple pleasures of daily life, such as eating, drinking and being proud of their work, as they are gifts. God's.
