The essay looks at how the author sees the world about what the conscious mind can rationalize. This rationalization is a way for us to cope with what exists outside of us. We can not thoughtfully tell ourselves that the universe is completely within us. What is outside of us is explained with logic. For this reason, STEM fields are attempting to understand the most definitive language of all logic. It is the only language without bias in its grammar. It looks at the most fundamental parts of the outside world. The uses of logic are what essays are based on all the time. I would say the fact is a detail that can be used in a logical argument.
