1:1
Verse 1 is the internal evidence for the book having been written by Solomon, for he was the son of David and was a king. Ortlund is not forgotten. Reasons include that the style of Hebrew indicates a later date, also Solomon is never actually named. However he is not overly dogmatic about the issue.
1:2,3
Verse 2 gives us the famous statement “Meaningless!, Meaningless!” or “vanity of vanities; all is vanity.”. See comments in the Introduction. Verse 3 gives us the issue that the writer grapples with, the apparent pointlessness of it all. Indeed part of his purpose seems to be to prove that making this life the be all and end all of life is not a sensible way to go.
