Am I fascinated with consumer technology or fascinated by it? What about a book, an object, or a philosophical idea?


With: If the object of the fascination is something that can be held, handled, or manipulated (Rubik's cube for example), then someone can be fascinated "with" it.

I was fascinated with his car.

By: If - for example - someone is reading an interesting article, they may be fascinated "by" it.

I was fascinated by her voice.

  • What about a philosophical idea? This is a "thing", but not something you can hold. Or "consumer technology"? This is a class of things, so which does it fit in?

  • I'll use by with both of them. They're ideas or concepts rather than being physical things. I checked Oxford, Webster and Longman. All were using examples using "by".

    What about Japan? Can I be both fascinated with Japan and fascinated by Japan because it's a thing and a whole bunch of ideas?
