Can anyone tell me what this quote would fall under in terms of literary elements?

I am currently doing my homework and I came upon this quote in my book. I know it is some sort of literary element but I am at a lost as to what it is. Does anyone know what it is? It might even be more than just one but I am not sure.
Heres the quote “Each station should be like a beacon on the road towards better things, a centre for trade of course, but also for humanizing, improving, instructing.”
