I like his saying much better than the old Roman adage, but the Roman version is (no surprise) much more popular in our world. Do a Google search for each, in quotes and you see that one version appears on the internet 3.7 million times, while the other a paltry 23 thousand and change.
There is also a considerable disparity between "fight fire with fire" and "fight fire with water", though not so great in amplitude.
