What is the origin of the phrase in light of?

Dictionary states that both of the phrases “in light of” and “in the light of” have been used since the late 1600s. The third variant, “in view of,” has been used since roughly the year 1800. Etymonline also confirms this. They state that the usage of light meaning “some consideration which puts something in a certain view” has been used since the 1680s. 

While both of these websites states when the term initially came into popularity, neither can pinpoint exactly where the phrase was first used or what the etymology of the phrase was. It has a slight relation to the phrase “to shed light on.” If someone sheds light on something, that means that they are providing information about it. This goes along with the metaphor that in the light means in a place where there is knowledge and information. Thus, “in light of” or “in the light of” something came to mean because of the knowledge or information gained about a certain thing, person or event.

Hi Mark,

Unfortunately in light of the plagiarism we discovered during last week’s exam, I have no choice but to fail you in this course and report you to the dean of students. Cheating is not something we take lightly here, and we have a zero-tolerance policy. You will be hearing from the dean.
