Three Stages of Twilight - Michael O'Connor - Bog

There are three stages of twilight which all start after sunset and end before sunrise. The differences are a matter of degree. The truth is that there are three conceptions as to what constitutes truth: agreement of a thought and reality; eventual verification; and consistency of thought with itself. The differences are also a matter of degree. What happens when it begins to get dark is a range of a thing in time space, and how it is remembered is a matter of interpretation.
