Ecclesiastes 1:11 - Matthew Poole's English Annotations on the Holy Bible

There is no remembrance of former things: this seems to be added to prevent this objection, There are many new inventions and enjoyments unknown to former ages. To this he answers, This objection is grounded only upon our ignorance of ancient times and things, which is very great, and which if we did exactly know or remember, we should easily find parallels to all present occurrences in former ages. The latter clause tends both to illustrate and confirm the former. The sense is, There are many thousands of remarkable speeches and actions done in this and the following ages, which neither are, nor ever will be, put into the public records or histories, and consequently they must unavoidably be forgotten and lost unto succeeding ages; and therefore it is just and reasonable to believe the same concerning former ages, seeing the same causes are most likely to produce the same effects.
