I would suspect the claim is using a specific understanding of "break". Obviously you can break a human mind with a bullet or a chisel through the eye socket, but there are certain types of breakage that are not possible without much more nuanced understanding of how the mind functions. In general, I think the idea is that when we learn to create a type of thing, we also learn a great deal about new ways to destroy it.
