Frankly, I think the people who are saying they think purely without words are full of shit. But that's just me.
The example of food Trollwhisperer provided above is true, and I'm sure there are many other instances of thinking with "feelings". But don't tell me, someone who speaks several languages doesn't have words going through their minds when they're working through their thoughts. That's absurd.
In my personal opinion, that would only be true if you were living by yourself on an island your whole life. If anything, the formation of words and languages helped develop cognitive abilities throughout history. Ever heard of constructivism in education? The idea of constructivism is pretty big in schools these days and it's basically the concept of how we build on past knowledge to increase our learning skills ... mainly thinking.
