what does という mean here


> 人間とは月のような存在だ。他人には満月を見せていて、人 **という** 光にあたって誰もが輝いて見えているが、その裏側は黒く、暗いものだ

is 人という光 a contract form of "人というのは、光" or it means "light called humman"?




This 人という光 means "light called human" or "light that is human". The sentence
says that every human has an external-facing side that looks bright like a
full moon because it's "illuminated by (the light called) other people".

> 他人には満月を見せていて、人という光にあたって誰もが輝いて見えている
>
> They show the "full moon" (side of themselves) to others; everyone looks
> bright, illuminated by the light called people.
