‘Nishijima Roshi used to say that every philosophy but one fell into either the category of materialism or the category of idealism. Buddhism, he said, was the only exception. This is why the Buddhist worldview is so hard to understand. Whenever we encounter a philosophy that denies the materialistic view, we tend to think of it as idealistic. It’s almost impossible not to do so.

In fact, in terms of how our thinking works it may actually be impossible to hold a worldview that is neither materialistic nor idealistic in our thoughts. Thought insists on seeing things one way or another. It can’t contain contradictory viewpoints. And yet reality itself is not limited to the categories our thoughts insist upon. 

This is why Nishijima Roshi called Buddhism a “philosophy of action.” It is a philosophy that you experience in real action in the present moment. This is why Dogen used deliberate contradictions as a way of pointing out the limitations of language and thought to ever fully explain reality.’ (from Hardcore Zen)

I don’t feel I need to get too philosophical about this, but I agree with the overall premise here, and I think that Dogen might boil it down to ‘reality itself is not limited.’
