Objective Reality

Greetings!

I am new to this site so I am not sure I am using it properly. If it is allowed, I would like to post a request to help me find a source.

At a lecture I heard the following quote, “There is no such thing as objective reality, just imaginary moments that become real.” This is a quote of what the lecturer said, although he may have been paraphrasing. The lecturer credited the quote to a philosopher, but did not name the philospher. The impression left by the lecturer was that the philosopher was from the 20th century.
As a physicist, I am extremely curious about what the philosopher was asserting. It is very hard to agree or disagree with, or to even interpret, a one sentence statement, but it is intriguing.
Does any member or visitor to this website have any idea who the philosopher was that put forth the above assertion? I would like to read some of his or her works, but cannot find a way to begin.
